It would be nice to add this to the wiki
maybe here:
wiki.linuxcnc.org/cgi-bin/emcinfo.pl?ClassicLadderExamples
What slaves devices are you using?

Maybe you can figure out how to connect CL as a TCP slave as well.
Its possible but not tried on EMC

Hello Chris....
At the moment I'm using two different slaves but same manufacturer (Schneider Electric) the first one is named Zelio (it is a smart relay)
and the second one is named TWIDO (it is a small class full feature PLC very flexible and scalable).
The Modbus TCP/IP seems to work fine and in this way it very easy to add a lot of Analog and Digital I/Os to be used by ClassicLadder PLC task (and connected woth EMC2).
For the Wiki use I need to know how to implement the information into, so please can you help me ?
About the Modbus Slave functinality I will test this soon and I will give to you the feedback.
As a Modbus Slave ClassicLadder will only be passive into a Modbus network (because Modbus is not a multimaster network class).
This means an external master manage the Read and Write functionalities.

look here for steps to add to wiki:
wiki.linuxcnc.org/cgi-bin/emcinfo.pl?BasicSteps
Yes to test classicladder as a slave you must have two compoters running classicladder (one as master) or have some other master.
I hope you can figure this out.
is this similar to your plc?:
cgi.ebay.com/TELEMECANIQUE-TWIDO-STARTER...?hash=item4cee833b72

Yes it is Chris.
The plc that you show is the modular one (there is also a compact version that is what I'm using) and you can find out more information about it on internet at the official website
of Schneider Electric for TWIDO TAKE A LOOK . By default the built in communication port can be used also as a Modbus over serial line . TWIDO can have a second communication port (very cheap) and attacched to this is possible to use a gateway Ethernet-->serial line (named Twidoport) and communicate with Modbus TCP/IP.
The code for the gateway is 499TWD01100.
Anyway for the application of EMC2 and CL+Modbus TCP/IP I think that every hardware device that is Modbus TCP/IP compliance can be used.

Hello Chris....
At the moment I'm very busy so I need to wait a couple of weeks , because I want to test also the Modbus TCP/IP slave mode.
I've already the material and the software tools to test it ...... but the time.
So please be patient and I will do the job.
I check every day the messages on the forum to be up to date about the arguments that the users discuss.

Sorry for my English.
I have siemens material (S7-200, S7-1200, S7-300) and Schneider can do some tests.

Hello to forum,
where the stalled project.
Give us more details.
How do I connect EMC-CL with modbus to plc simulator on www.plcsimulator.org?
I ask for concrete examples.

I used a usb to serial adapter on the windows side.
to connect to the EMC computer I used a special cable.
I believe it was a serial lap-link cable. Used for connectting two computers together using the serial port.
This cable had four female connectors on it, because it could except either the db25 or db 9 connectors.
As for TCP , I never could figure it out. But someone else did.
