TM4C Ethernet Interface

Hello Manoj,

A very generic question. Do note that for PLC to read data from a TM4C microcontroller there needs to be a compatible software running on the TM4C device.

Hi Amit,

Thanks for your response. Can you briefly explain the procedure how one can read data in TM4C from Generic PLC via Ethernet Interface or let share literature about it.

Thanks in Advance

Hello Manoj,

Which "specific" PLC are you referring to?

Regards
Amit

Hi Amit,

Mitsuibshi L series PLC of model MELSEC-L02CPU-P

Regards
Manoj

Hello Manoj,

Unfortunately, we do not have the full "functional" protocol details on this PLC and quite some others. The ethernet implementation must come from the manufacturer.

Amit

Hi Amit,

if you have procedure for any other PLC, Please share. it will be easy for me to discuss with Mitsubishi PLC vendor and understand how to establish communication.

Manoj

Hello Manoj,

Apologies again, but I do not have a documentation for the same. I can check around with my co-workers.

I would be surprised if such an implementation exists. Most PLC-internal protocols are proprietary, and Closed Source.

Field bus resources, OTOH, are often freely available (Modbus TCP being one example).

Hello f.m.

I have seen PLC controllers specifying a target software, but as you said there is a lot of propitiatory information.

Amit
