canbus and siemens s7-1200

[oferyosef]

hi
is it possible to use v350 with canbus v100-17-can or v100-s-can communicating to siemens s7-1200 ?
i need the siemens s7-1200 read few tags from the unitronics v350 via canbus
i use the other ports to read data from other instruments.

is there any example ?

thanks

I Googled "S7-1200 Protocols" and found it supports CANOPen.  So the answer to your question is yes.  But I personally can't tell you how.

Search the forum for CANOpen posts for some ideas on how to make it work.

thanks

the card v100-17-can can be use to communicate to s7-1200 ? or it only connect to other unitronics plc ?

The V350 PLC together with the expansion card v100-17-can supports the standard CANopen protocol, some Unitronics PLC to PLC protocol ect.

In general, the PLC provides for the implementation of CANopen network management - i.e. starting network devices, managing their status, transmitting PDOs, receiving RPDOs and sending SDOs. That is, it is assumed that the PLC is actually the master of the network. I can claim that these actions are successfully performed by the PLC, I have implemented and tested it.

However, I did not conduct experiments with the connection of the CANopen network to another PLC - in your case Simatic 1200, which in my opinion also involves work with external devices for which it should actually also be a master.

Theoretically, master-to-master work is possible, but its implementation can be difficult without appropriate experience and additional equipment.
