Publication 17476.14 - March 1996 Chapter 1 Quick Start for Experienced Users This chapter helps you to get started using the 1747-APB module; a DP slave (adapter) that can be used with any PROFIBUS DP master. We base the procedures here on the assumption that you understand the PROFIBUS network and DP protocol. You also must have a basic understanding of programmable controller products. Because it is a start-up guide for experienced users, this chapter does not contain detailed explanations about the procedures listed. It does, however, reference other chapters in this book where you can get more information. If you have any questions, or are unfamiliar with the terms used or concepts presented in the procedural steps, always read the referenced chapters before trying to apply the information. This chapter: • tells you what tools and equipment you need • lists preliminary considerations • describes how to configure the 1747-APB module • explains how to install and wire the 1747-APB and I/O modules • describes connection of the PROFIBUS DP network • lists the information needed for configuring the DP master for communication with the 1747-APB module • discusses system power-up procedures Required Tools and You must supply the following equipment to connect your Equipment 1747-APB module to a PROFIBUS DP network (see chapter 3 for more information): • a 9 pin D-sub connector • network connection equipment For Line Type A (baud rates up to 1.5M bit/s): shielded twisted pair cable (We recommend Belden PROFIBUS cable, 3079A.) For Line Type B (baud rates up to 500k bit/s): drop cables, T-junction connectors, and bus segment cables (We recommend Sprecher + Schuh equipment.) • termination blocks, if the devices on the end of the network do not have built-in terminating resistors (We recommend Sprecher + Schuh, Catalog Number PCE-0, Part Number 87.890.284-01.)

Topics include: • introduction to PROFIBUS DP • communication between DP masters and DP slaves • PROFIBUS DP products available from Allen-Bradley Introduction to PROFIBUS DP is the performance-optimized version of PROFIBUS DP PROFIBUS. It is a remote I/O protocol designed for high-speed data transmission between automation systems and distributed peripherals, such as remote I/O chassis or operator interface panels. PROFIBUS DP is most useful for time-critical communication. There are two main devices on the PROFIBUS DP network: the DP master(s) and DP slave(s). The DP master acts as a requester of data from the DP slaves. A DP master of controller type (Class 1) may also act as a responder to requests made from a DP master of management type (Class 2). The DP slaves act only as responders to a DP master, implementing a defined set of functions. These functions are: • data exchange • check configuration • set parameters • read diagnostics • get configuration � • global control • read output • read input ` • set slave address � Only Clear Data is supported by the 1747APB module. ` Not supported by the 1747APB module. Communication Between The PROFIBUS DP network uses the polling principle for DP Masters and DP Slaves communication, in which the DP master sends and requests information, and the DP slave sends back a response. This is a cyclic exchange of information that occurs independently from the actual update of the database by the DP master and DP slave application. Publication 17476.14 - March 1996 2–2 PROFIBUS DP Overview Before data exchange begins, each device on the network must have a unique station number assigned to it. (See chapter 6 for information on setting the 1747-APB module’s station number.) How Data is Exchanged on the Network To exchange I/O data with the DP slaves on the network, the DP master must have sets of parameter and configuration data for each DP slave. This data contains all the information necessary to define the DP slave. In addition, the DP master’s parameter data includes bus parameters and an address assignment table. Data is exchanged over predefined Source and Destination Service Access Points (SSAPs and DSAPs). The maximum size of data that can be exchanged is 244 bytes. Defining the DP Slave Data The structure of the DP slave configuration data can be divided into a maximum of 64 logical modules, (however, the 1747-APB module supports 30 due to physical slot limitations), each with as many as 16 words of input and or output data. The configuration also specifies whether the data is sent in bytes or words. When communication begins, the DP master sends the DP slave parameter data and information on what it expects is the DP slave’s configuration data. Upon receipt, the DP slave compares this information to its actual configuration. If the master’s information does not exactly match the slave’s actual configuration, a fault occurs. (See chapter 4 for specific information on defining data for the 1747-APB module.)

Equipment Needed for Line Type A Cables You must use a shielded twisted pair cable for your connections. Off-the-shelf cables can be used to connect your adapter to a PROFIBUS DP network; however, we recommend using Belden PROFIBUS cable, 3079A (for baud rates up to1.5M bits/s). Termination Blocks Termination blocks are only needed if the devices or connectors on the end of the network do not have built-in terminating resistors. Connector Connect your adapter to the PROFIBUS DP network by attaching a bus connector to the socket 9 pin D-Sub connector on the front of the module. We recommend using any of the following Siemens connectors: Catalog Numbers 6ES7 972-0BA00-0XA0, 6ES5 762-2AA12, or 6ES7 193-9AA00-0XA0.

Connect data signal pins on both ends (Signal+, Pin #3 and Signal–, Pin #8). 3. Connect data ground pins on both sides. The data ground pin (Pin 5 of the PROFIBUS DP connector) is also connected by an R/C filter to 1746 I/O chassis ground. Publication 17476.14 - March 1996 3–6 Connecting to the PROFIBUS DP Network 4. The cable connector hood is connected to chassis ground directly through the adapter cover. For compliance with the European Electromagnetic Compatibility (EMC) directives, also connect the cable shield to metal shroud of connectors on both sides: this will connect the cable shield directly to local chassis ground at all points on the PROFIBUS DP network, thus bypassing the adapter R/C filter. Important: For improved noise immunity in networks featuring long distances, an alternate wiring may be preferred to avoid dc and low frequency ground loops. In such cases, connect the cable shield directly to local chassis ground (via the cable connector hood) at only one point on the PROFIBUS DP network. 5. Terminate the PROFIBUS cable at both ends of the network. If your adapter is located at one of the ends, you must terminate at the PROFIBUS DP connector or T-junction.

This chapter explains the information required. The following topics are presented: • entering DP slave data using the device data base • entering configuration data • entering parameter data For information on defining the bus parameters and the location of � I/O data within the DP master data tables, see your DP master’s user manual. Entering Slave Data Using For ease of configuring your master, a disk containing an electronic the Device Data Base device data base is shipped with each 1747-APB module. If your PROFIBUS master’s configuration software has the capability to read this *.gsd file (DP standard Device Data Base file), the software will automatically extract from this file all the configuration and parameter bytes needed to configure your master for the 1747-APB module. Otherwise you will probably need to manually enter this information into the software. (See your configuration software’s user manual for more information.) See appendix B for an example Device Data Base file. Publication 1747�6.14 - March 1996 4–2 Configuring the PROFIBUS DP Master Entering Configuration Upon communication startup, the master’s I/O configuration data is sent to the 1747-APB module, for the module to compare with its Data own I/O configuration data. It contains the range of input and output areas as well as information on data consistency. On a PROFIBUS DP network, the I/O data exchanged between the PROFIBUS DP master and a DP slave is encapsulated into logical modules. One logical module can contain up to 16 words maximum of inputs, outputs, or combined inputs/outputs. The total I/O data exchanged between a PROFIBUS DP master and a DP slave device comprises a set of logical modules, described in configuration data. For the 1747-APB module, each slot of the adapter chassis or expansion chassis corresponds to one logical module. An understanding of the physical layout of the chassis will help you define the logical modules. Understanding Slot Numbering The 1747-APB module is capable of controlling 1 to 30 physical I/O modules (within the restraints of the PROFIBUS data limits), each of which resides in a chassis slot. When expansion chassis are used, the 1747-APB module treats all of the I/O modules as if they are installed in a single chassis. (For more information on adapter chassis and expansion chassis, see chapter 10.) The adapter chassis and expansion chassis slots are numbered from 0–30. Slots numbered 31 and above cannot be used. The 1747-APB module must reside in slot 0, as shown below. Important: Installing modules in slots 31 and above causes a 1747-APB module error.

Important: With the 1747-APB, you cannot assign more than one physical module to a logical module, and vice versa. If attempted, a 1747-APB configuration error occurs. Creating the Configuration Data Important: The configuration data in the master must exactly match the physical configuration of the adapter chassis; otherwise the initialization process of the adapter module will fault, and no I/O communication will occur. Each logical module is described with a DP identifier byte, containing information on the type and point size of the physical module residing in a slot. Important: If a slot is empty, a corresponding logical module must still be included as part of the configuration data. (See page 4–5 for an example.) The following table lists the physical modules that the 1747-APB module supports, along with the corresponding DP identifier bytes that describe the logical modules. The table also provides the I/O type, number of words, and data consistency for each module in case your master’s configuration software requires you to manually enter this information.

Adapter – Any physical device that is a slave on the PROFIBUS DP network. The 1747-APB module is an adapter. Baud Rate – The speed of communication between devices on a network. All devices must communicate at the same baud rate. Calculated Watts – The amount of heat generated by those points energized on an I/O module. Chassis – A hardware assembly that houses the 1747-APB module, a power supply, and I/O modules. Discrete I/O Module – An I/O module used to sense or control two-state (ON/OFF) devices. CSA – Canadian Standards Agency. DIN – German Normalization Agency. DP – Decentralized Periphery. A German/European standard (DIN 19245, Part 3) that specifies a simplified user interface with PROFIBUS link layer services and protocol, for use with decentralized peripherals. Expansion Chassis – A hardware assembly that connects to a chassis using a 1747-C9 (91.4 cm [36 in]) or 1747-C7 (15.2 cm [6 in]) cable. It houses a power supply and I/O modules. Input Device – A device, such as a push button or a switch, that supplies signals through input circuits to a programmable controller. I/O – Inputs and Outputs I/O Module – Any 1746 or 1747 I/O module that is supported by the 1747-APB module. LED – Light-emitting Diode. Logical Module – Features up to 16 words maximum of inputs, outputs, or combined inputs/outputs. The I/O data exchanged between a PROFIBUS DP master and a slave device comprises a set of logical modules. Maximum Watts – The maximum amount of heat that the module generates with field power present. Publication 17476.14 - March 1996 G–2 Glossary Minimum Load Current – The lowest amount of current at which the output is designed to operate. Operating at or below this value is not reliable. Minimum Watts – The amount of heat dissipation that can occur when there is no field power present. Module Slot – Also called slot. A location in a chassis or expansion chassis for installing a module. Each module slides into a module slot that lines up with a backplane connector. Network – A series of stations (nodes) connected by some type of communication medium. A network may be made up of a single link or multiple links. Node – Also called station. An address or software location on the network. Nominal Input Current – The current at nominal input voltage. Off-State Current – For input circuits, the maximum amount of leakage current allowed from an input device in its Off-state. Off-State Leakage – For output circuits, the maximum amount of (leakage) current that may flow when the output circuit is in its Off-state. Off-State Voltage (max) – The maximum input voltage level detected as an Off condition by the input module. On-State Voltage Drop – The voltage developed across the output driver circuit during the On state at maximum load current. Operating Voltage – For inputs, the voltage range needed for the input to be in the On state. For outputs, the allowable range of user-supplied voltage. Output Device – A device, such as a pilot light or a motor starter coil, that is energized by the programmable controller. Physical Module – Any 1746 or 1747 I/O module that is supported by the 1747-APB module. Points per Common – The number of input or output points connected to a single return (common) or supply (vcc). PROFIBUS – PROcess FIeld BUS. A German standard (DIN 19245/Part 1, 2, and 3) that specifies a fieldbus for communications at the process level. Publication 17476.14 - March 1996 Glossary G–3 Protocol – The “language” or packaging of information that is transmitted across a network. RTB – Removable Terminal Block. Signal Delay – For inputs, the response time required to transmit the circuit status from the field wiring to the digital logic. For outputs, the time required to transmit the circuit status from digital logic to the output wiring. Sinking – A term used to describe current flow between an I/O device and SLC I/O circuit — typically, a sinking device or circuit provides a path to ground, low, or negative side of power supply. Sinking/Sourcing – Describes a current signal flow relationship between field input and output devices in a control system and their power supply. Sourcing I/O modules supply (or source) current to sinking field devices. Sinking I/O modules receive (or sink) current from sourcing field devices. Slot – Also called module slot. A location in a chassis or expansion chassis for installing a module. Each module slides into a slot that lines up with a backplane connector. Sourcing – A term used to describe current flow between an I/O device and SLC I/O circuit — typically, a sourcing device or circuit provides a path to the source, high, or positive side of power supply. Specialty I/O Module – An I/O module other than a discrete I/O module (e.g., an analog module). See page 10–23 for a list of specialty I/O modules supported by the 1747-APB module. Station – Also called node. An address or software location on the network. Surge Current Per Point – The maximum amplitude and duration (pulse) of current allowed for a given period of time and temperature. Surge Suppressor – A device used to absorb voltage transients created by energizing an inductive load to reduce electrical noise or to protect the output circuit. For example, an R-C network, MOV (metal oxide varistor) or diode. Watts Per Point – The maximum heat dissipation that can occur in each field wiring point when energized.
