Twido CPU Model: TWDLMDA40DTK

Ok first, I have Three (3) TWDLMDA40DTK PLC CPU. I'm planning to have a master and two (2) slaves. Can someone save me from here... I'm having a hard time establishing communication between these three CPU's.

Second, does anybody know how to fabricate its communication cable the 8 pin mini din cable?

Thanks in advance!!! Hope someone help me...

What connection are you using, RS485, Ethernet etc ?

The documentation for the Twido programming cable has a RS485 pinout for the 8-pin mini-DIN port you're talking about. I'm not sure how much that'd help you though.

take a look for twido help file for com_macro build in functions.

You can use rs232/485 or ethenet (ethernet modbus master only if twido have build in ethernet port)

its better have 2nd com port on plc, so you can also debug program same time. You can use programming port also for rs485 modbus, but then you can't communicate same time than program.

p.s TWDLMDA40DTK have only programming port, so it's recomended to buy additional communication port for PLC's. (NOZ485T)

I am using RS485.
