Publication 1790-SG001B-EN-P - March 2009 Chapter 3: Specify a CompactBlock I/O System 33 In addition, CompactBlock I/O modules on the DeviceNet network have these features: • Input Filtering • Idle and Fault Mode Selection • DeviceLogix Functionality • Optional I/O Assemblies Input Filtering Input filtering limits the effect of voltage transients caused by contact bounce and/or electrical noise. If not filtered, voltage transients could produce false data. To configure an input filter, an input signal delay is set to turn off-to-on or on-to-off for nominal amounts of time. The mode and filter time is set through RSNetworx for DeviceNet software, or a similar configuration tool. Idle and Fault Mode Selection When the PLC, SLC, or PC-based programmable controller is in Program mode, the DeviceNet scanner puts the CompactBlock module in an idle state. If the DeviceNet scanner drops off the network, the module goes to a fault state. In both idle and fault states, the module resets its outputs by default. You can use RSNetworx for DeviceNet software or a similar configuration tool to change the default and set the module to save the last received outputs. Hold Last State (HLS) Fault HLS State Use Fault Value 0 Fault Apply 0 To Output Value 1 Apply 1 To Output Fault state can be set to HLS or use fault value. The fault value can be set to 0 or 1. The same logic applies for idle conditions. 42455 Publication 1790-SG001B-EN-P - March 2009 34 Chapter 3: Specify a CompactBlock I/O System DeviceLogix Functionality The CompactBlock I/O family also offers modules that have DeviceLogix capability, a local logic that provides you with the ability to control outputs and manage status information locally, within the device.DeviceLogix capability is configured through a function block editor that is accessed through RSNetW orx for DeviceNet software. This editor lets you create local logic by using boolean operators, such as AND and OR, set and reset latches, as well as a variety of timers and counters. User support for the editor can be found in the DeviceLogix Ladder Editor User Manual, publication ACIG-UM002, and online help. CompactBlock products that support DeviceLogix technology have some device-specific capabilities and capacities, which are identified in this table. Capability/Capacity CompactBlock I/O Modules Function blocks supported • Boolean - AND, OR, XOR, NOT, NAND, NOR, XNOR • Latches - RSL and SRL • Timers - PUL, OND, and OFD • Counters - UPC and UPD Number of function blocks 48 included in a configuration, max Function block processing time 1 ms/24 blocks 2 ms/48 blocks Network input bits 32 Network output bits 8 Available status bits • Explicit message connection • Polled connection • Change-of-state/cyclic connection • Network fault • Minor module fault • Polled connection fault • Polled connection idle • Change-of-state/cyclic connection fault Logic status indication • Logic disabled - none • Logic enabled - solid green • Local forces are applied and local logic is enabled - flashing green Optional I/O Assemblies The DeviceLogix-capable versions of CompactBlock I/O modules give you the ability to choose how much data the modules produce or consume over the DeviceNet network. Two new parameters have been added to the EDS files that let you select the amount of data that will be transmitted or received. Publication 1790-SG001B-EN-P - March 2009 Chapter 3: Specify a CompactBlock I/O System 35 Produced I/O Assembly These three options are for Produced Data: • Default assembly - Produces the device’s input data and any fault/status data the device has. • Input only assembly - Produces only the state of the device’s inputs. This lets those who do not make use of the Diagnostic bits reduce their network traffic. • DeviceLogix assembly - Produces all of the standard information from the Default assembly plus the data that is available as a result of invoking DeviceLogix technology. These new DeviceLogix data are available: – Logic Enabled bit - This bit is high when the DeviceLogix configuration is running on a device and has been enabled. This can be used, for example, in the PLC program or on a DeviceNet MMI to indicate the presence of local logic control. – Network Output bits - These bits are used in the DeviceLogix configuration to send information back over the network. For example, the output of any function block can be connected to a network output bit. – Hardware Output bits - The DeviceLogix configuration lets you locally control the state of hardware outputs. Therefore these bits are produced by the device so that the state of the outputs can be sent back to the network master. If an output in the device is not under DeviceLogix control, its status is still controlled by the normal consumed data. Please refer to the CompactBlock I/O for DeviceNet Technical Data, publication, 1791D-TD001. The assemblies for CompactBlock I/O devices are listed in the publication, in the sections that contain specific module information. Consumed I/O Assembly DeviceLogix technology provides the device the ability to consume data from the DeviceNet master other than the normal state of the hardware outputs. This data is called Network Input Bits. Up to 32 of these bits can be consumed by the device. Five options exist for the variable amount of consumed data: 0, 1, 2, 3, or 4 bytes. A standard 16-output CompactBlock I/O module, for instance, consumes 16 bits (2 bytes). With DeviceLogix technology, you can choose to consume an additional 2 bytes of Network Inputs. If a hardware output is controlled by local logic, its state is no longer consumed and that bit becomes available to be used as a Network Input. For more on this concept, please refer to the DeviceLogix Ladder Editor User Manual, publication ACIG-UM002.

DeviceNet Communication The distributed I/O module (CompactBlock LDX I/O or CompactBlock I/O) acts as a slave in a master/slave environment. I/O data is exchanged with the master through a polled, cyclic, or change-of-state connection. This selection is made in the DeviceNet scanner module's configuration. Polled When configured as a polled device, a master initiates communication by sending its polled I/O message to the distributed I/O module. Cyclic When using cyclic operation, the master sends data only to the distributed I/O module and receives only data from the module at a preconfigured time interval. Change-of-state When the distributed I/O module is configured for change-of-state, the master sends output data only when: • the user's control program wants to update the module's output. • the time period for communication has expired. 41 Publication 1790-SG001B-EN-P - March 2009 42 Chapter 4: Network Specifications The distributed I/O module's input data is sent to the master only when: • an input changes. • the time period for communication has expired. With change-of-state, the master does not have to request input data from the slave. It is sent automatically when data changes. In addition, an adjustable "heartbeat" is produced periodically by the distributed I/O module to let the consuming device know that the module connection is alive and ready to communicate. Software and EDS File Requirements CompactBlock LDX I/O and CompactBlock I/O modules require RSNetWorx for DeviceNet software, version 3.0 or later. We recommend the use of RSNetworx for DeviceNet software, version 7.0 or later. Additionally, current functions of CompactBlock LDX I/O modules require current, modular EDS files for RSNetWorx for DeviceNet software. These files are easy to install and are available online at http://www.ab.com/networks/eds/. EDS files for modules with matching catalog numbers (for D-shell and terminal block versions) are the same. On the website or in RSNetWorx for DeviceNet software, you can see only one catalog number listed for both versions. Power Supply Requirements The DeviceNet network supplies power to the CompactBlock I/O base and expansion modules. Inputs and outputs are powered by an external 24V dc source that is independent of the network. Publication 1790-SG001B-EN-P - March 2009 Chapter 4: Network Specifications 43 CompactBlock LDX I/O and CompactBlock I/O modules are PROFIBUS DP Network compatible with any PROFIBUS DP scanner. PROFIBUS DP Communication Optimized for high speed and inexpensive installation, the PROFIBUS DP network (decentralized periphery) is designed especially for communication between programmable controllers (PLCs) and distributed I/O at the device level. Data exchange is mainly cyclic with field devices such as I/O, valves, drives, and measuring transducers. The primary controller (master) reads the input information from the field devices (slaves) and sends the output information back to the slaves. The communication functions required for this are highlighted in this table and are defined by the PROFIBUS standard. Basic PROFIBUS DP Functions Bus access • Token passing procedure between masters and master-slave procedure between master and slaves • Mono-master or multi-master system possible • Master and slave devices, maximum 126 stations on one bus Communication • Peer-to-peer (user data communication) or multicast (control commands) • Cyclic master-slave user data communication Operating states • Operate - cyclic transmission of input and output data • Clear - inputs are read, outputs remain in secure state • Stop - diagnostics and parameterization, no user data transmission Synchronization • Control commands allow the synchronization of inputs and outputs • Sync mode - outputs are synchronized • Freeze mode - inputs are synchronized Functions • Cyclic user-data transfer between DP master and slave • Dynamic activation or deactivation of individual slaves • Checking the configuration of the slaves • Powerful diagnostic functions, three hierarchical levels of diagnostic messages • Synchronization of inputs and/or outputs • Address assignment for slaves optionally possible via the bus • Maximum of 244 bytes input and output data possible for each slave Publication 1790-SG001B-EN-P - March 2009 44 Chapter 4: Network Specifications Basic PROFIBUS DP Functions (Continued) Protective • All messages are transmitted at a hamming distance of HD=4 functions • Watchdog control of DP slave detects failure of the assigned master • Access protection for inputs/outputs of slaves • Monitoring of user data communication with adjustable monitoring timer in the master Device types • DP master Class 2 (DPM2), for example engineering or diagnostics tool • DP master Class 1 (DPM1), for example central programmable controllers such as PLC, SLC, PC • DP slave, for example devices with binary or analog inputs/outputs, drives, valves Data communication is monitored on both the master and slave sides. Speed The PROFIBUS DP network requires about 1 ms at 12 Mbps to transmit 512 bits of input data and 512 bits of output data to 32 stations. Diagnostics Diagnostic messages are transmitted over the network and collected at the master and are classified into these three types: • Station-related - Status of the device (for example, low voltage or over temperature, depending on the device). • Module-related - Indicates if any of the connected I/O modules report errors. More detailed information of the error can be found by evaluating the channel-related diagnostic message. • Channel-related - Provides information on channel errors of the I/O modules and expands on the module-related diagnostics. System Configuration and Device Types The PROFIBUS DP network consists of mono-master or multi-master systems. This allows flexibility during system configuration. A maximum of 126 master or slave devices can connect to one network. System configuration specifications define: • the number of stations. • assignment of station addresses to the I/O addresses. • data consistency of the I/O data. Publication 1790-SG001B-EN-P - March 2009 Chapter 4: Network Specifications 45 • format of the diagnostic messages. • bus parameters. Publication 1790-SG001B-EN-P - March 2009 46 Chapter 4: Network Specifications Each PROFIBUS DP system consists of these three different types of devices: • DP Master Class 1 (DPM1) - This is a central controller that cyclically exchanges information with the distributed stations (slaves) in a defined message cycle. This device is typically the PLC. • DP Master Class 2 (DPM2) - This is a configuration or operating device used for commissioning, maintenance, or diagnostics. It also evaluates measured values and parameters and requests device status. This device is typically the scanner or adapter. • Slave - This is a peripheral I/O field device such as an HMI, drive, relay, or sensor. Depending on the type, the slave device collects input information and sends output information to the peripherals. The maximum amount of input and output information is 244 bytes of input and 244 bytes of output. Mono-master systems contain only one PLC on the network. The field devices are decentrally linked to the PLC via the transmission medium. These systems offer the shortest communication time. Multi-master systems contain several PLCs on one network. These systems can be configured either with independent subsystems each consisting of one DPM1 master and its assigned slaves, or with additional configuration and diagnostic devices. Input and output information of the slaves can be read by all masters, however only one master can write-access the outputs. Operating Modes and System Status In addition to the cyclic data exchange that is executed automatically by the master, the master can send control commands to a single slave, a group of slaves, or all slaves simultaneously. These control commands are transmitted as multicast commands and permit use of Sync and Freeze modes for event-controlled synchronization of the slaves. Sync/Freeze The slave begins Sync mode when it receives a sync command from the assigned master. The output channels of all I/O modules are then frozen in their current state. During subsequent user-data transmission, the output data is stored in the scanner, but the output states remain unchanged. The stored output data is not sent to the Publication 1790-SG001B-EN-P - March 2009 Chapter 4: Network Specifications 47 outputs until the sync command is received. Sync mode is concluded with the unsync command. Publication 1790-SG001B-EN-P - March 2009 48 Chapter 4: Network Specifications Similarly, a freeze control command causes the adapter to assume Freeze mode. In this operating mode, the states of the input channels of all I/O modules are frozen at the current value. Input data is not updated again until the master sends the next freeze command. Freezemode is concluded with the unfreeze command. General system behavior is determined by the operating status of the master. These are the three main states: • Stop - No data transmission occurs between the master and the slaves. • Operate - The master is in the data transfer phase. In cyclic data communication, inputs of the slaves are read and output information is written to the slaves. • Clear - The master reads the information of the slaves and sets the outputs to an idle state. The system reaction to an error during the data transfer phase of the master (suchas slave failure) is determinedby theauto clear configuration parameter. If this parameter is set to true, the master switches the outputs of all assigned slaves to fail-safe state as soon as a slave is no longer ready for user data transmission. The master then changes to the clear state. If this parameter is false, the master remains in operate state even when a fault occurs with the user specifying the proper system reaction. Cyclic Data Transmission Data transmission betweenthe master and its slaves isexe cutedautomatically by the master in a defined, recurring order. When configuring the network, the user defines the assignment of a slave to the master. At this time, the user also defines which slaves are to be included or excluded from the cyclic user data communication. This transmission of data is divided into three categories: • parameterization • configuration • data transfer Before a slave enters the data transfer phase, it is checked in the parameterizationa nd configuration phasesto determine whether the planned configuration matches the actual device configuration. During this check, the device type, format and length information and the number of inputs and outputs must agree. These checks offer reliable protection against parameterization errors. Inad dition to the userdat atransfer Publication 1790-SG001B-EN-P - March 2009 Chapter 4: Network Specifications 49 which is executedautomatically bythe master, new parameterizationdata can be sent to the slaves at the user’s request. Configuration and GSD File Requirements You can configure CompactBlock I/O modules using GSD files and any PROFIBUS DP configuration package. The GSD files are available online at: www.ab.com/networks/gsd/ Base Module to Expansion Interface The base module is linked to the expansion module with an 8-bit parallel bus, control lines, Vcc and ground connections, a reset/initialization line, and an expansion presence line. The 8-bit bus is multiplexed so that 16 bits of data (1 for each I/O point) can be transmitted/received with two transfers. The reset/initialization line is used during initialization of the module. The presence line is used for the detection of an expansion module at power up and for a period of each data transfer. Module ID is read over this bus at power up. 1791P modules supply expansion power via expansion bus as follows: Expansion power voltage 5V dc Expansion power current 100 mA Power the Module An external power supply for the PROFIBUS network is required for CompactBlock I/O and CompactBlock LDX I/O base modules. Inputs and outputs are powered by an external 24V dc source which is independent of the network.
