Posted 16 Sep 2009 (edited) Here is what I am trying to do: I am trying to connect a CPX772 to wonderware through serial port 1 through GESNP (on the wonderware side). I have configured all places to setup the serial ports on the pc to match the configuration on the plc. I am able to connect to the plc with LM90, but I am unable to connect with GESNP. The cable pinout I am using is IC693CBL316A. It has a DB9 on the pc end and an RJ11 on the plc. Does anyone have any idea as to why this doesn't work? A little side note: I am not going to upgrade away from LM90, this system will not be there that long anyway. This system communicates TCP primary, this is for a backup in case of a network failure.

Posted 18 Sep 2009 (edited) I suggest that you verify the SNP ID, with wonderwhere you will need to use an SNP ID, LM90 does not need one. Also I think that each port on the 90-70 can be assigned its own ID. Are you using the RJ-11 or the 15pin-D port with LM90?

Posted 18 Sep 2009 I have entered an SNP ID for the cpu overall, I have not for each interface. If I do it for each interface, it will require a processor stop and download. I am using the RJ11. Share this post Link to post Share on other sites
Posted 18 Sep 2009 Okay then, you know that the cable works and what the Baud, Parity, Stop bits are, if WanderWhere still is lost, I would bet that the SNP ID is wrong or missing in WanderWhere. Share this post Link to post Share on other sites
