Dear List members
I am looking for information on Modbus Plus protocol. I have checked the modbus.org site for the same but could not get details on the following points. The modbus.org website site does not give any information of Modbus Plus.
1) Is Modbus Plus protocol an open protocol? (To my understanding Modbus ASCII/ RTU & TCP are open protocols while Modbus Plus is Schneider Automations proprietary protocol. Is this true?)
2) What physical layer does this protocol work on?
3) Where can I find technical information necessary for driver development? Whom should I contact to get the protocol details? (If this not a proprietary protocol?)
4) Can I put a device supporting Modbus RTU protocol (supporting serial communication) to Modbus Plus network? How?
Thanking you in anticipation.
