[KRABB]AC500 HA programming
Please check if OPC server is mandatory for AC500 HA redundancy.
Is HA-Libarary 2.4 installed on PC or included in Codesys?
If the library is in Codesys then I think OPC server is not mandatory, doesn,t it?

CoDeSys OPC server for AC500-HA is required when you want to feed the OPC data to SCADA system. The CoDeSys OPC Server allow you create a topic name that alias with both AC500 CPU and automatic switching base on the status of the AC500 CPU.
The latest AC500-HA library (version 2.4.3) is bundle with Automation Builder 1.2.4. This library is the aids to make the redundancy.
If you dion't have and SCADA or MES on top of AC500-HA, then CoDeSys OPC Server is not require.
