Could anyone tell me if there is card that sits in the rack of a 115u (944) siemens PLC, that will enable comms over a MODBUS+ network. What is
available on the market and how to it. Help very much appreciated. Thanks.

Hi
It's the CP-523. This has only one connection.
The CP-525 has 2, however I don't know if it works in the 115U.
About the modbus+:

im=0&nodeID0=4000129&siteid=cs&jumpto=64

Is a link to the support site. I has a example for modbus. I don't have experience with modbus but the manual:

"http://www4.ad.siemens.de/csinfo/livelink.exe/fetch/1109143/cp523en.pdf?func=doc.Fetch&nodeid=1118059":http://www4.ad.siemens.de/csinfo/livelink.exe/fetch/1109143/cp523en.pdf?func=doc.Fetch&nodeid=1118059

might help.
At least a start,
zan

You need an appropriate CP module and the loadable function blocks for MODBUS.

See your Siemens rep. or the website "http://ad.siemens.com":http://ad.siemens.com
