AC500 HA redundancy and HMI CP650
Hello Gents,
After migration from CONTROL BUILDER to AUTOMATION BUILDER v1.2.4 the writing discrete commands from CP650 don't work. CODESYS ETH protocol is used for exhanging data between two PLC (HA redundancy) and one HMI CP650.
As per manual for AC500_High_Availability_User_Manual_V240 (CS31 limitations) the writing commands from HMI is not reccomended by ABB -
Could somebody explain - Will remote commands writing in revision of HA library 2.3 or not?
As I understood the Modbus TCP/IP is more preferable for exchanging data with HMI.
May be somebody have a example og logic and configuration for MOdbus TCP/IP?
