Overview of the IC693PCM301

The GE IC693PCM301 is a Programmable Coprocessor Module designed to extend the processing capabilities of the Series 90-30 PLC. It provides the necessary hardware support for running applications that are not native to the Series 90-30 controller, such as those written in Basic Programming Language (BAS). This makes it ideal for applications in Supervisory Control and Data Acquisition (SCADA) systems, where custom executable files are needed.

The module features a 25-pin D-shell port, effectively integrating Port 1 and Port 2 for communication. This port supports Modbus RTU and GE Fanuc CCM protocols, enabling data exchange with external devices like programming terminals, CRTs, bar code readers, scales, and Remote Terminal Units (RTUs).

The IC693PCM301 also offers a convenient restart pushbutton, allowing for module initialization without rebooting the entire rack or requiring software interventions. The module’s LED indicators, including Module OK, US1, and US2, provide real-time status updates for monitoring its performance.

Key Benefits

Extended Processing Power: Runs non-native applications like BAS for SCADA systems.
Flexible Communication: Supports Modbus RTU and CCM protocols for seamless data exchange.
Memory Expansion: 192 Kbytes of memory, with 47 Kbytes dedicated to Megabasic applications.
Efficient Setup: Easy integration into the Series 90-30 PLC system, with no need for external racks or software restart.
Battery Backup: Equipped with a lithium battery to preserve memory and prevent data loss.

The IC693PCM301 is an essential addition to the Series 90-30 PLC family, enabling more complex automation tasks and better integration with other industrial devices. Its simple installation, powerful memory capabilities, and flexible communication protocols make it a valuable solution for a wide range of industrial applications.
