Dear colleagues, I would like to ask you what are the limitations for OPC UA, I mean how many OPC UA clients can I connect to PLCnext?
Hi Luis, The number of concurrent OPC UA client sessions (not clients) is limited to the number specified by the “MaxSessionCount” parameter in this configuration file on the PLC: /etc/plcnext/device/Services/OpcUA/opcua.settings We are planning to update the OPC UA server documention in the Info Center in the coming months with this (and more) information. ~ Martin.
