Customer Questions and Answers

• Question:  What is an IC693CMM302?  Answer:  The IC693CMM302 is an Enhanced Genius Communications module. This model gives you advanced data communications. A series of IC693CMM302's can be interconnected on the Series 90-30 PLC structure.
• Question:  What rack size can I use for the IC693CMM302?  Answer:  You can use any standard Series 90-30 CPU rack, I/O rack, or remote I/O rack.
• Question:  How many Genius Communications Modules can be installed in a Series 90-30 PLC?  Answer:  In a Series 90-30 PLC, 2 or more GCM+ modules can be installed. Each GCM+ has its own Genius bus, which can serve up to 31 additional devices. (That means a Series 90-30 PLC equipped with 2 GCM+ modules can exchange global data with as many as 62 other Genius devices automatically.)
• Question:  Besides basic global data exchange, what other applications can the IC693CMM302 be used for?  Answer:  The IC693CMM302 can be used for the following: data monitoring by a personal or industrial computer, monitoring data from I/O blocks, communication among devices on the bus, and emulating remote I/O for the Series 90-30 by allowing another device on the bus to read input data and control output data in a Series 90-30 PLC. (For configuration of these uses please see our datasheet user-manual.)
• Question:  What is the difference between a GCM+ and a GCM?  Answer:  The GCM is an earlier, less powerful version of the GCM+. Both types of modules can be used on the same bus, but they cannot be installed in the same PLC. These two types of modules can exchange global data with each other. 
• Question:  What does the error message REF ER indicate?  Answer:  The IC693CMM302's error message REF ER may indicate either the reference address assigned to that SBA exceeds the reference limit for the PLC or the SBA message offset (plus the length of the reference assigned to the SBA) exceeds 128 bytes.
• Question:  What does the error message REF ADJ indicate?  Answer:  The IC693CMM302's error message REF ADJ may indicate that references have been adjusted (rounded) down to a byte boundary or, for discrete references, the reference length for the SBA has been rounded up to a byte boundary.
• Question:  What does the error message GCM ERR indicate?  Answer:  The IC693CMM302's error message GCM ERR may indicate that too many GCM+ modules have been configured (the limit is 3) or you have tried to configure a GCM+ module and a GCM module in the same PLC. (The GCM+ cannot be installed in the same PLC as a GCM module.)
• Question:  What do the error messages IOM ERR, I/O ERR, and DAT ERR indicate?  Answer:  IOM ERR may indicate that the GCM+ module is not available. I/O ERR may indicate that you have assigned reference addresses that overlap references already assigned. And DAT ERR may indicate a parameter (such as the Series Six reference address) is out of bounds.
•  Question:  If IC693CMM302 error messages will not go away, what is my next step?  Answer:  If IC693CMM302's error messages will not go away, please visit our repair page.
