4 Overview CompactBlock I/O for PROFIBUS DP
System Compatibility CompactBlock I/O modules are compatible with any PROFIBUS DP scanner.
CompactBlock I/Oon PROFIBUS DP
Optimized for high speed and inexpensive installation, PROFIBUS DP (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 the following table and are defined by the PROFIBUS standard.
Basic DP Functions
Data communication is monitored on both the master and slave sides.
Speed
PROFIBUS DP requires about 1 msec at 12 Mbit/sec to transmit 512 bits of input data and 512 bits of output data to 32 stations.
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, 3 hierarchical levels of diagnostic messages• Synchronization of input and/or outputs• Address assignment for slaves optionally possible via the bus• Maximum of 244 bytes input and output data possible for each slave
Protective Functions
• All messages are transmitted at a hamming distance of HD=4• 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), e.g., engineering or diagnostics tool• DP master Class 1 (DPM1), e.g., central programmable controllers such as
PLC, SLC, PC• DP slave e.g., devices with binary or analog inputs/outputs, drives, valves
Publication 1791P-TD001B-EP - October 2002
CompactBlock I/O for PROFIBUS DP Overview 5
Diagnostics
Diagnostic messages are transmitted over the network and collected at the master and are classified into 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 Devices Types
PROFIBUS DP 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• format of the diagnostic messages• bus parametersEach PROFIBUS DP system consists of three different types of devices:
DP Master Class 1 (DPM1) - this is a central controller which 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 request 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.This system 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.

6 Overview CompactBlock I/O for PROFIBUS DP
Operating Modes and System Status
Sync/Freeze
In addition to the cyclic data exchange which is executed automatically by the master, the master can send control commands to a single slave, a group of slaves or all slave simultaneously.These control commands are transmitted as multicast commands and permit use of sync and freeze modes for event-controlled synchronization of the slaves.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 outputs until the sync command is received. Sync mode is concluded with the unsync command.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. Freeze is concluded with the unfreeze command.General system behavior is determined by the operating status of the master. The three main states are:• 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 (such as slave failure) is determined by the auto 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 between the master and its slaves is executed automatically 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.
Publication 1791P-TD001B-EP - October 2002
CompactBlock I/O for PROFIBUS DP Overview 7
This transmission of data is divided into three categories:• parameterization• configuration• data transferBefore a slave enters the data transfer phase, it is checked in the parameterization and configuration phases to 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. In addition to the user data transfer which is executed automatically by the master, new parameterization data can be sent to the slaves at the user’s request.

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:
