Hi,

When using the TLM2/3 Controller from Berger Lahr, we assume you have selected the eds file and configured it correctly in the PLC Configurator.

When the Beckhoff I/O module appears on the CANopen network it will produce a bootup message and during this time the TLM2/3 will be searching for the object 1000:0 (Idx:Sidx). If the slave answers to this object 1000 correctly then the TLM2/3 will initialise the slave correctly.

Often it can be the case that the response is not coded correctly in the eds file and so this prevents the TLM2/3 from initialising the slave.

I encourage you to use a CAN analyser (if you can) to look at what's happening OTW (On the Wire) which is preventing the TLM2/3 from successfully initialising the slave device.

I haven't used that module but I know all the basics have to be covered:

Hope this helps

Hello Guys,

I am really struggling to get a Berger-Lahr TLM controller to even see my Beckhoff remote I/O module over CANOpen. I know the bus is working as when I disconnect this unit and connect my Festo CPV-10 valve terminal it works like a dream.

I guess the question is has anyone used the BK5120 CAN bus coupler successfully. As a qwerk I am using an analogue input and four encoder inputs and no outputs...

Any thoughts????
