Where are you initiating the COMM_REQ?

If issuing in the Series 90-70 then GFK-0582D chapter lists CCM secondary error codes reported in the high byte of the CCM Status Word after the execution of a CCM COMMREQ. These codes also appear in the low byte of CCM Diagnostic Status Word (DSW) 1. Neither 58 nor 90 appear in this list.

If porting the Series 90-70 application to the RX3i then the COMM_REQ probably needs modifying. GFK-2460G lists the CCM functions supported by the IC695CMM002/4 modules. Not all commands are supported.

I am assuming that the 90-70 side you are using IC697CMM711 as CCM protocol master, RX3i side IC695CMM002/004 as CCM slave， in the RX3i side, there is a tab "PortData_CCM_Salve1", you have to assign Ref Length for CCM slave

In reply to Jimmy Lee:

Yes, to clarify, RX3i CMM module can only be a CCM slave. Conversion to another form of communciations, such as EGD over Ethernet for peer-to-peer, is recommended.
