  • Page 19: Power Distribution Modules

    2.2.3 Electronics Modules (Standard Product Line) The standard electronics modules contain the I/O-functions of the BL20 modules (power distribution modules, digital and analog input/output modules, and technology modules). They are plugged onto the base modules and are not directly connected to the wiring and can be plugged or pulled when the station is being commissioned or for maintenance purposes, without having to disconnect the field wiring from the base modules.

  • Page 20: Eco Electronics Modules

    ECO Electronics Modules New ECONOMY modules with a high signal density and exceptionally low channel price expand the BL20 I/O bus terminal system. Depending on type, up to 16 digital inputs and outputs can be connected on only 13 mm. This high connection density considerably reduces the mounting width required for typical applications.

  • Page 26: System Overview

    PROFIBUS-DP (Decentral Periphery) is designed for data transfer between the control and the input/ output level. TURCK BL20 stations support PROFIBUS-DP. PROFIBUS-DP is the speed-optimized PROFIBUS version, specially designed for communication between automation devices and decentralized peripheral devices. PROFIBUS-DP is suited to replace cost-intensive parallel signal transmission via digital and analogue sensors and actuators.

  • Page 28: Transmission Rate/Cycle Times

    Note Premoulded PROFIBUS-DP cables simplify network installation, shorten set-up times and reduce wiring errors. TURCK offers an extensive and varied product spectrum for this purpose. The ordering information on the available cable types can be taken from the respective product catalogue.

  • Page 29: Diagnostic Functions

    Channel-related diagnostics Here the error cause of a single input/output bit, i.e. relating to a single channel, is indicated. Example: "Short-circuit at output 2" The PROFIBUS slaves of the BL20 series support the diagnostic functions of PROFIBUS-DP. The evaluation of the diagnostic data via the control depends on the support of the master. Note Further information on diagnostics can be taken from the device descriptions of the master interfaces of the various manufacturers.

    PROFIBUS-DP is based on DIN 19 245 Parts 1 and 3, and has been integrated into the European fieldbus standard EN 50 170. Note The BL20 gateway can only be used as slave on PROFIBUS-DP. The gateway has no master functionality. All manufacturers of control systems offer plug-in network cards for their PLCs, to which BL20 gateways can easily be connected if they are meeting the PROFIBUS-DP standards.

Typical sources of interference are, for example, parallel-routed signal cables, contactors and electrostatic discharges. D301106 1211 - BL20-ECO PROFIBUS-DP 10-1...

Least Significant Bit Mass All interconnected inactive components that do not take on a dangerous touch potential in the case of a fault. 10-3 D301106 1211 - BL20-ECO PROFIBUS-DP...
  • Page 174 Mode of operation in which a station acting as a master controls the communication between other stations in a bus system. Module bus The module bus is the internal bus in a BL20 station. The BL20 modules communicate with the gateway via the module bus which is independent of the fieldbus. Most Significant Bit Multi-master mode Operating mode in which all stations in a system communicate with equal rights via the bus.
