Servus, I'm using OPAUA Interface for my first Program, but there are some problems with communication when i write int and float format variables in my PLCs. In Figure 3 and 4 I try to write INT values to "robotArmSuccess" but in OPC Server the corresponding values are not changed. Then I read Demo of OPCUA and modify my Program with the function WriteNodeValue(NodeId, value) , it did not work in PLC Server, according to figure 1 and 2 . Could you please give me some Guidance for this situation?
