IC200BEM002 Network Slave Module: PROFIBUS Connectivity Guide for VersaMax PLC
Product Introduction
The IC200BEM002 functions as a PROFIBUS-DP slave communication module for the GE Fanuc VersaMax series. This network slave module allows a VersaMax PLC system to operate as a slave device on a PROFIBUS-DP network. The module reads and writes reference table data as though it were conventional bit- and word-type I/O data. Furthermore, multiple IC200BEM002 modules may reside in the same VersaMax PLC system simultaneously. The module processes up to 244 bytes of input data and transmits up to 244 bytes of output data. In addition, the firmware resides in FLASH memory and supports serial upgrades via PC connection.
Core Value
Firstly, the IC200BEM002 delivers seamless PROFIBUS-DP connectivity for VersaMax distributed I/O architectures. Secondly, its auto-detection capability for baud rates from 9.6 Kbaud to 12 Mbaud eliminates manual configuration errors. Thirdly, the module supports up to 32 stations without repeaters and expands to 125 stations with repeaters. Moreover, the compact DIN-rail design simplifies control cabinet integration. Meanwhile, LED indicators provide immediate visual feedback for power and communication status. Therefore, maintenance personnel can quickly identify fault conditions without specialized diagnostic tools.
Technical Insights
The IC200BEM002 adheres to the PROFIBUS DP-V0 slave profile. Its 9-pin D-sub connector accepts standard PROFIBUS DP cabling with characteristic impedance between 135 and 165 ohms. The module draws 460 mA from the 5V backplane bus. Besides, the station address configures through rotary switches on the faceplate, with valid addresses ranging from 0 to 125. Specifically, addresses 0 and 1 typically serve master-class devices, so slave addressing starts at 2. In addition, the module supports I/O data mapping consistent with the VersaMax I/O image.
Installation & Maintenance
Firstly, mount the IC200BEM002 on a conductive, unpainted DIN rail to ensure proper grounding. Secondly, set the PROFIBUS station address using the rotary switches before powering the system. Thirdly, connect the PROFIBUS DP cable to the 9-pin D-sub connector, maintaining correct polarity: green wire for A (+) and red or blue for B (-). Moreover, enable the built-in termination resistors via DIP switches when the module resides at a bus endpoint. Furthermore, verify that the master configuration I/O byte length matches the slave settings. During operation, monitor the OK LED for module health and the COM LED for active data exchange. For firmware updates, connect a PC to the headend device serial port and perform a serial download. Finally, inspect connections periodically and keep the module away from heat sources.
