AXC F 2152 as a OPC UA Client calling method

MAMMAM
in PLCnext Technology & PLCnext Controls

Hello,

i'm using a AXC F 2152 controller as a OPC UA client reading some values from an external OPC UA Server. On this one we have not only variables but some methods as well. Is there any possibility to call a method on the OPC UA Server from the PLC used as a client?


Thanks and regards

Marco

    Hello, according to the "Profile and facets" section on this page of the Info Center:

    https://plcnext.help/te/Communication_interfaces/OPC_UA/OPC_UA_client.htm

    ... the OPC UA Client does not currently support the Method Client Facet, so I am afraid that the answer is no (sorry).

    Thanks for the answer Martin.

    Other question,

    do you know if is it on "road plan" to improve the client? For example to call methods or also be able to read string variables?

    Thanks and regards

    Hi Marco, there are two questions there:

    1. Plans to add features like Method calls to the OPC UA Client in the PLCnext Runtime.

    Yes, there is a list of features that are planned to be added to the OPC UA Client, but unfortunately it's not possible to say if or when any of those features will be added to the PLCnext Runtime, apart from anything that appears in the "Roadmap" section of the Info Center.

    2. Plans to allow String variables to be selected in PLCnext Engineer.

    This is an artificial restriction that has been imposed by PLCnext Engineer, and is not a limitation of the PLCnext Runtime. This has been reported in the past, so I will ask someone from the PLCnext Engineer support team to give an update on any plans to remove this restriction.
