>> 560 reports a fault as well?
SI 236 shows error "6", that's mean that I have: CANbus Warning error Poor transmission quality due to faulty wiring, or if the cable length exceeds recommendations.
&
One or more networked units cannot be read. If this bit is ON, check SI 238, SI 240-243.

>> Com init settings definitely OK? Baud rate definitely the same?
Yes. My DIP switches are 0 1 1, so my gateway is set also as 20 Kb
Earthing OK?
Yes. It is.
Polarity correct?
I think so.
V- is grey one, V+ is a black one.
Electrically checked all connections are ok?
Yes, they are.
Tried altering the Turck address to one either side of what it is meant to be via the DIPs in case they have some strange numbering quirk?
If You ask if I tried different gateway IDs - yes, I tried to connect devices using different adresses, but nothing happened.
I also tried to run it on lowest rate, but also there happened nothing.
Additional informations:
- I tried to put extra resistor between H & L at PLC but nothing happened. (Btw. CANbus network termination resistor is in V560 standard kit contents, so it shouldn't be neccesarry I think. Or maybe i have to turn it on manually?
- I also tried to make as short cables as possible. Nothing happened Thank You for your help, I appreciate it a lot, but maybe You have any idea of another solutions? Cheers, Rzasior.
