The POINT I/O module (B) snaps into the base. The removable terminal block (C) also snaps into the base and provides the wiring and terminations for field-side connections, as well as system power for the backplane. POINT I/O has 4 major components: • I/O modules provide the field interface and system-interface circuitry • Communication interface modules provide the network-interface circuitry • Terminal base units provide the wiring and signal termination for field-side connections and system power for the backplane • Power distribution modules provide the expandability of the POINT I/O system and the flexibility to mix a variety of signal types 1734 POINT I/O modules offer 1 to 8 points per module. The I/O modules are interfaced to a network through a communication interface, which includes a built-in power supply that converts incoming 24V DC power to 5V DC backplane power. Each type of communication interface (Network Adaptor) supports a maximum of 13 to 17 I/O modules, with a maximum of 10 A field power. The I/O modules receive power from the power supply through the backplane. With an external power supply, you can expand a POINT I/O assembly up to a maximum of 63 I/O modules or 504 channels. 1734D Series POINTBlock I/O provides a DeviceNet communication interface with up to 16 integrated I/O points in a single module. You can add up to 13 POINT I/O modules to a POINTBlock I/O assembly, for a maximum of 120 channels per assembly.

NetLinx Open Network Architecture is the Rockwell Automation NetLinx Open Network strategy of using open networking technology for seamless, top-floor Architecture to shop-floor integration. The NetLinx-based networks – DeviceNet, ControlNet, and EtherNet/IP – all use the Common Industrial Protocol (CIP), so they speak a common language and share a universal set of communication services. NetLinx architecture, part of the Integrated Architecture platform, seamlessly integrates all the components in an automation system from a few devices on one network to multiple devices on multiple networks including access to the Internet – helping you to improve flexibility, reduce installation costs, and increase productivity. • The EtherNet/IP network is an open industrial-networking standard that supports implicit and explicit messaging and uses commercial, off-the-shelf Ethernet equipment and physical media. • The ControlNet network allows intelligent, high-speed control devices to share the information required for supervisory control, work-cell coordination, operator interface, remote device configuration, programming, and troubleshooting. 9Publication 1734-SG001D-EN-P - September 2010 10 Select POINT I/O Communication Interfaces • The DeviceNet network offers low-cost, high-speed access to plant-floor data from a broad range of plant-floor devices and a significant reduction in wiring.

It emerged due to the high demand for using the Ethernet network for control applications. The EtherNet/IP network uses off-the-shelf Ethernet communication chips and physical media. The EtherNet/IP network provides excellent drive and I/O control performance along with HMI information processing and many commercial technologies. EtherNet/IP Network Considerations Adapter Considerations 1734-AENT A total of 63 POINT I/O modules can be assembled on a single 1734-AENTR EtherNet/IP node. Expansion power supplies may be used to provide additional POINTBus backplane current. Refer to the User Manual to determine the ratings for direct and rack connections allowed. The 1734-AENT/1734-AENTR adapter supports direct- and rack-optimized connections. A direct connection is a real-time data transfer link between the controller and whatever module occupies the slot that the configuration data references. Direct-connection messaging occurs at a cyclic rate specified by the requested packet interval (RPI) during configuration. A rack-optimized connection is a grouping of data from more than one I/O module into a single block of data sent over a single connection at the same data rate. Rack-optimized connections reduce the total number of connections needed to transfer data when using many I/O modules in a system. Assume a system contains 8 digital I/O modules interfaced to a 1734-AENT/1734-AENTR adapter. If you used direct connections to transfer data to each of these modules, you need 8 connections — one to each of the 8 I/O modules. If you use a rack-optimized connection to transfer the Publication 1734-SG001D-EN-P - September 2010 12 Select POINT I/O Communication Interfaces data, you need only a single connection — the connection to the 1734-AENT/1734-AENTR adapter. 1 34 5 2 EtherNet/IP 12121345 45102 1734-AENT/1734-AENTR 1734-AENT/1734-AENTR Technical Specifications 1734-AENT/1734-AENTR Input Voltage, Nom. 24V DC Input Voltage Range 10…28.8V DC Field Side Power Requirements 400 mA @ 24V DC (+20% = 28.8V DC) Inrush Current 6 A for 10 ms POINTBus current (mA) 800 (1734-AENTR) 1000 (1734-AENT) Power Consumption at 24V 4.5 W Power dissipation, max. 2.8 W @ 28.8V Input Overvoltage Protection Reverse polarity protected Interruption Output voltage will stay within specifications when input drops out for 10 ms at 10V with max load. The ControlNet network is an open, state-of-the-art control network ControlNet Network that meets the demands of real-time, high-throughput applications. The ControlNet network uses the proven Common Industrial Protocol (CIP) to combine the functionality of an I/O network and a peer-to-peer network providing high-speed performance for both functions. The ControlNet network gives you deterministic, repeatable Publication 1734-SG001D-EN-P - September 2010 Select POINT I/O Communication Interfaces 13 transfers of all mission-critical control data in addition to supporting transfers of non-time-critical data. ControlNet Network Considerations Adapter Considerations 1734-ACNR A total of 63 POINT I/O modules can be assembled on a single ControlNet node. Expansion power supplies may be used to provide additional POINTBus backplane current. Up to 25 direct connections and 5 rack connections are allowed. The 1734-ACNR ControlNet adapter provides high-speed transfer of time critical data between controllers and I/O devices. It manages data transfers between controllers on the ControlNet network and POINT I/O modules plugged into the POINTBus backplane. The ControlNet network allows the exchange of messages between ControlNet products compliant with the ControlNet International specification. The 1734-ACNR adapter features include a variety of control system solutions, local communication network access through the network access port (NAP), and redundant media. It requires Series C POINT I/O modules or later. The 1734-ACNR adapter requires a typical 24V DC power supply with a maximum of 10.2 W of power. It provides a maximum backplane current of 1.0 A at 5V DC. Backplane current can be extended beyond 1.0 A with a 1734-EP24DC backplane extension power supply. The 1734-EP24DC can supply up to an additional 1.3 A of backplane current. Multiple 1734-EP24DC power supplies can be used to reach the maximum limit of 63 POINT I/O modules if 25 or fewer of these modules are analog or specialty modules. The adapter supports 25 direct and 5 rack I/O connections to the POINT I/O modules. From a single 1734-ACNR adapter, multiple controllers establish I/O connections, up to a maximum of 5 rack I/O connections per adapter. Direct connections must be used with analog and specialty modules. Multiple rack connections permit multiple controllers to connect to I/O over a single 1734-ACNR adapter. The number of connections that can be supported on a network depends on the ControlNet parameters (NUT, RPI, and API) and the POINT I/O configuration by itself (number and types of I/O modules). The following example shows a single POINT I/O ControlNet adapter with 5 connections and 8 I/O modules. The POINT I/O modules are monitored by the 5 controllers on the ControlNet network. The POINT I/O modules in: • slots 1, 3, and 5 are controlled by the first controller. • slots 2 and 4 by the second controller. • slot 6 by the third controller. • slot 7 by the fourth controller.

When developing an application, the amount of data used by an individual connection must also include a small amount of overhead (I/O bytes per connection). The following formula tracks the amount of available scheduled transmit data. Available Memory = 586 - [(Number of connections * 10) + Sum of all connection sizes] In the following example, the system uses a 1734-ACNR adapter with five 1734-232ASC modules.

The DeviceNet network is an open low-level network that provides DeviceNet Network connections between simple industrial devices (such as sensors and actuators) and higher-level devices (such as PLC controllers and computers). The DeviceNet network uses the proven Common Industrial Protocol (CIP) to provide the control, configure, and data collection capabilities for industrial devices. The POINT I/O family offers four interfaces for connecting to the DeviceNet network. DeviceNet Network Considerations Adapter Consideration 1734-ADNAll POINT I/O modules count as a single node on the main network. A total of 63 POINT I/O modules can be assembled on a single DeviceNet node. Behaves as a slave device on the main network and a master on the POINTBus backplane. RSNetWorx for DeviceNet software is needed for configuration of the 1734-ADN adapter on the main network and the POINTBus backplane Expansion power supplies may be used to provide additional POINTBus backplane current. Publication 1734-SG001D-EN-P - September 2010 16 Select POINT I/O Communication Interfaces DeviceNet Network Considerations Adapter Consideration 1734-ADNXActs like a 1734-ADN adapter , with additional capabilities. All POINT I/O modules, and some third-party field devices, count as a single node on the main network. Has a second, Phoenix-style connector that extends the subnet off the module, so that any DeviceNet-capable device could be connected to a subnet and scanned by the 1734-ADNX adapter. Network on the second connector is electrically isolated from the main network and can be used to extend (1) the total DeviceNet trunk line distance. Node numbers of the devices on the POINTBus backp lane and subnet would not count against the 63 slave nodes allowed on the main network. Devices on the subnet and the main network need to be connected at different communication rates or use different sampling methods (for example, change-of-state or polled). Data from these devices would be included in the data being sent to/from the 1734-ADNX adapter on the main network. POINT I/O expansion power supplies are permitted and may be required to add more modules. 1734D POINTBlock Each POINT I/O module on the main network counts as a separate node. Series Appears to the main network as a 1734-PDN communication interface with a single, 16-point module attached. Any of the I/O modules may be attached in the same manner they are added to a 1734-PDN communication interface. Total POINTBus backplane current of I/O modules cannot exceed 1.0 A. Expansion power supplies may not be used. 1734-PDNEach POINT I/O module on the main network counts as a separate node. Electrically connects the main network to the I/O modules, which are connected on the POINTBus backplane. No configuration to the 1734-PDN communication interface necessary since it is transparent to the main network. Total POINTBus backplane current of I/O modules cannot exceed 1.3 A. Expansion power supplies may not be used. (1) For example: with thick round media at 125 Kbps, you could run a maximum of 500 m (1640 ft) to a 1734-ADNX adapter on the main network. You could then wire an additional 500 m (1640 ft) of cable on the subnet connector and double the distance of the network. Remember that this subnet needs terminating resistors and a 24V DC power connection, the same as any other DeviceNet network. It is important that the total amount of data coming from the subnet does not exceed the data capability of either the 1734-ADN or 1734-ADNX adapter. • 250 bytes (248 data + 2 bytes command info) for output data (used as either COS, cyclic, or poll) • 250 bytes (248 data + 2 bytes status info) for polled input data • 250 bytes (248 data + 2 bytes status info) for COS/cyclic input data • 8 bytes (6 data + 2 status info) for strobe input data The data coming through the 1734 adapter combined with the other data from the main network cannot exceed the data capability of the Publication 1734-SG001D-EN-P - September 2010 Select POINT I/O Communication Interfaces 17 main network master scanner. If this occurs, you will need multiple master scanners on the main network and the I/O modules on the subnet will need to be split between multiple 1734-ADN or 1734-ADNX adapters. With the 1734-PDN communication interface, the multiple masters on the main network will be able to communicate to separate groups of modules on its subnet through the same 1734-PDN communication interface, so no additional adapter would be necessary. About the 1734D Series The 1734D POINTBlock series is a set of DIN-rail mounted products with an integrated DeviceNet communication interface, various combinations of onboard I/O points, removable terminations, and a POINTBus expansion port. The DeviceNet interface presents the integrated I/O as a single DeviceNet node while expansion I/O modules will appear as separate nodes. The 1734D series includes a nonisolated DeviceNet communication interface. The 24V DC from the DeviceNet connection powers a nonisolated DC/DC converter that generates +5V DC. This +5V DC powers the 1734D series electronics and connects to the POINTBus port to power the expansion I/O electronics.

Analog and temperature input modules support the following configurable parameters and diagnostics: • open-wire detection with LED and electronic reporting • four-alarm and annunciation set-points: low alarm; high alarm; low/low alarm; high/high alarm calibration mode detection and electronic reporting • under-range detection and electronic reporting • over-range detection and electronic reporting • channel signal range and on-board scaling (scaling to any 16-bit integer under-/over-range alarms) • filter type (notch for A/D, or first-order low-pass digital filter) • temperature scale (Celcius, Fahrenheit, Kelvin, Rankine, or custom) • channel update rate (step response plus 0…10,000 ms filter setting) Choose analog or temperature I/O modules when you need: • On-board scaling eliminates the need to scale the data in the controller, preserving controller processing time and power for more important tasks, such as I/O control, communications, or other user-driven functions. • Over- and under-range detections and indications eliminate the need to test values in the control program, saving valuable processing power of the controller. • Ability to individually configure each channel of the output module to hold its last value or assume a user-defined value on a fault condition. • Ability to individually enable and disable channels improves module performance. • Selectable input filters lets you select from several different filter frequencies for each channel that best meets the performance needs of your application based on environmental limitations • Selectable response to broken input sensor feature provides feedback to the controller that a field device is not connected or operating properly. This lets you specify corrective action based on the bit or channel condition. • The modules share a high accuracy rating of ±0.1% of full-scale accuracy at 25 °C (77 °F).

Publication 1734-SG001D-EN-P - September 2010 30 Select POINT I/O Modules Temperature Input Modules POINT I/O temperature modules can detect and communicate these electronic conditions: Over-range alarm • The channel over-range alarm is set if the input is greater than the maximum temperature (thermocouple or RTD range dependent), millivolt (+75V) or resistance (600 Ω) range value, or above the maximum range of the thermocouple or RTD. • The cold-junction compensator has its own over-range alarm. If the CJC temperature goes above 70 °C (158 °F), the over-range alarm is set. Under-range alarm • The channel under-range alarm is set if the input is less than the minimum temperature (thermocouple or RTD range dependent), millivolt (-75 mV) or resistance (10 Ω) range value, or below the minimum range of the thermocouple or RTD. • The cold-junction compensator has its own under-range alarm. If the CJC temperature goes below 0 °C (32 °F), the under-range alarm is set. Level alarm • When the channel input goes below a low alarm or above a (low-low, low, high, high alarm, a bit is set in the data table. All alarm status bits high-high) can be read individually or by reading the channel status byte (bits 2…5 for channel 0; bits 10…13 for channel 1). • Each channel alarm can be configured individually. Open-wire alarm • The module has the ability to check for a broken or detached wire. In any mode, if a broken/detached lead is detected, the data value is forced to maximum and the over-range alarm is set. Once the alarm is issued, it remains active as long as the input signal is faulted. Cold-junction Compensation (1734-IT2I only) When using thermocouples, cold-junction compensation is required at the termination of the thermocouple wire. Cold-junction can be accomplished in three ways: • Enter an estimated temperature • Use a 1734-TBCJC mounting base (recommended) • Use external cold-junction compensators Entering an estimated temperature is the least accurate way for cold-junction compensation. Using external compensators is the most expensive way, while using the 1734-TBCJC provides the easiest and most accurate method. An open cold-junction compensator causes the input point to the maximum temperature value for the selected input type. This causes an alarm to be set. Once the alarm is issued, it remains active as long as the input signal is faulted (above maximum). Publication 1734-SG001D-EN-P - September 2010 Select POINT I/O Modules 31 Set the cold-junction enable bit on the 1734-IT2I module to enable or disable the cold-junction linearization. If enabled, the proper cold-junction compensation value is applied to the selected thermocouple. If disabled, the data (CJ temperature) is still available but is not applied to the input. If the 1734-TBCJC is not available, this parameter should be set to disabled. A cold-junction value can be added using the cold-junction offset parameter.

The three main functional blocks are the customer digital I/O interface, the counter ASIC, and the microprocessor. The counter modules accept feedback from: • Encoders (either single-ended or differential) • Pulse generators • Mechanical limit switches • Frequencies up to 1 MHz A filter is available with four settings: 50 Hz, 500 Hz, 5 kHz, 50 kHz. The filter can be turned off to achieve the fastest counting rate. The modules return the count or frequency in the form of a 24-bit binary number (0…16,777,215) expressed in a 32-bit word. Each counter has a user-selectable preset and rollover value associated with it. The counter modules operate in the following modes. • Counter mode — read incoming single-phase pulses, return a binary count. • Encoder mode — read incoming two-phase quadrature pulses, return a binary count. • Period/rate mode — count internal clocks during the on period, return a frequency (1734-VHSC24 and 1734-VHSC5 outputs are updated only at the end of the period). • Continuous/rate mode — count internal clocks during the on period, return a frequency (1734-VHSC24 and 1734-VHSC5 outputs are updated continuously during this period). • Rate measurement mode — read pulses during the sample period, return a frequency. • Pulse width modulation (PWM) mode — generate a pulse width modulated signal (1734-VHSC24 and 1734-VHSC5 only). • Pulse generator mode — generates a pulse of defined width, returns width and quantity of trigger (1734-VHSC24 and 1734-VHSC5 only). The operation of the counter and encoder modes is nearly identical. The difference between the two modes is in the type of feedback (one-phase versus two-phase) for the count direction (up or down). In encoder mode, a transition is expected on B for counting to proceed in a direction. In counter mode, the Publication 1734-SG001D-EN-P - September 2010 40 Select POINT I/O Modules B input may be left at a static level.

The I/O mounting base and removable terminal block are sold together (pre-assembled) as a single unit called a Terminal Base Assembly. The pins on the 1734-TB terminal base assembly are independent of each other. The connections for the 1734-TB and 1734-TB3 are determined by the 1734 module being used.

The RTB also provides vertical access to wire and screw terminations. A separate terminal point is provided for each wire, including a shield ground terminal point for 2-point analog modules. POINT I/O Removable Terminal Base Assembly A B 45103 Each terminal base assembly includes a base (A) that mounts onto the DIN-rail and a removable terminal block (B) for I/O wiring. Once the RTB is wired properly, you never need to rewire terminations. The RTB separates independently of the I/O mounting base and I/O module to facilitate rapid installation and commissioning of the system. Each terminal is numbered on the bottom of the RTB to simplify troubleshooting during commissioning or maintenance cycles. Spare or replacement RTBs can be ordered separate from the terminal base assembly. Terminal Base Assemblies Terminal Base Description Terminal Base Replacement Assembly Screw Torque RTB Cat. No. Cat.

The 1734-EP24DC or 1734-EPAC expansion power supplies provides Expansion Power Supplies two services: • Breaks the field power distribution at the left of the power supply (1734-EP24DC or 1734-EPAC) from the field power distribution to the right of the power supply (1734-EP24DC or 1734-EPAC) • Adds an additional 1.3 A of current to the POINTBus for I/O modules to the right of the power supply (1734-EP24DC or 1734-EPAC) The expansion power unit maintains the integrity of the POINT I/O backplane by not interrupting the POINTBus data. The 1734-EP24DC expansion power unit passes 24V DC field power on the POINTBus backplane to the I/O modules to the right of it. The 1734-EPAC expansion power unit passes 120/240V AC field power on the POINTBus backplane to the I/O modules to the right of it. These units extend the backplane bus power and creates a new field voltage partition segment for driving field devices for up to 17 I/O modules. The expansion power units separate field power from I/O modules to the left of the unit, effectively providing functional and logical partitioning for: • separating field power between input and output modules. • separating field power to the analog and digital modules. • grouping modules to perform a specific task or function. You can use multiple expansion power units with the 1734-ADN, 1734-ADNX, 1734-ACNR, 1734-AENT, and 1734-APB communication adapters to assemble a full system. For instance, if you are using the Publication 1734-SG001D-EN-P - September 2010 Select a Power Supply Unit 53 1734-ADN adapter, you can use a 1734-EP24DC or 1734-EPAC expansion power unit to add additional modules. For example, if you have a 36 module system with a 1734-ADN adapter, you have to add at least two or more 1734-EP24DC or 1734-EPAC expansion power units to provide more POINTBus current for modules to the right of the supply. • 24…5V DC converter (1734-EP24DC) 120/240V AC to 5V DC converter (1734-EPAC) • 1.3 A, 5V DC output (extend backplane power) • Starts new voltage distribution • Partitioning • Dark-gray color for easy visual inspection and identification You can use the 1734-EP24DC or 1734-EPAC expansion power supply only with POINT I/O adapters.
