GE Fanuc IC693PBM200

The GE Fanuc IC693PBM200 is a Master module designed for PROFIBUS DP networks, compatible with any Series 90-30 baseplate slot, with the exception of slot 1 in modular CPU baseplates. This Master module facilitates the bidirectional exchange of I/O data between an IC693 PLC and a PROFIBUS DP network. Key features include Synchronization and Freeze modes, alongside LED indicators for both the PROFIBUS-compliant communication and system status. Firmware updates can be executed via the service port. The module accommodates standard data rates and can connect to up to 125 DP slaves, supporting a maximum of 244 bytes of input and output data per slave. Configuration of the IC693PBM200 requires ME Logic Developer PLC programming software, version 3.0 or later. In the context of migrating from the HE693PBM101 PROFIBUS Master Module, users should note that the IC693PBM200's default slave status area is 128 points—double that of the HE693PBM101’s 64 points—which may necessitate adjustments based on prior usage. Furthermore, in contrast to the HE693PBM101, the IC693PBM200 operates in Clear Mode whenever the PLC is not actively scanning its I/O. The arrangement of slave status bits also differs between the two modules, with the HE693PBM101 following the configuration order and the IC693PBM200 adhering to bus address order. Additionally, there is a maximum data exchange limit between the CPU and the IC693PBM200 of 3,972 bytes for both input and output data, ensuring efficient management of communication within the system.
