Faceplate for 3rd party OPC Data
We want to create a faceplate for 3rd party opc data (e.g. PID Loop), i.e we have created PID Object type in Object Structure and add 'OPC Control Connection' as shown attachement '1', Then we added this object in Function Structure. and connected the Property of object with OPC variable in OPC tab. But when we subscribed for live data, we found 'Additem error' as shown in second attachement.
I tried my best, but cannot solved this problem.
Please suggest me.

Possibly you didn't connect this object type in the Control Structure.
Open Control structure find your object under OPC /r PLC control network and check the connection status.
I recommend you to test for live values, in control structure first.
in that way you can verify if everything is ok with your OPC conection.
then if you have good results you can go the object type structure and create your faceplate.

En.. Why did you create PID object for 3rd party OPC in the AC 800M/C Connect control type group? Of course you get AddItem error...

Deploy aspect can be found in PLC Generic Control network (Control Struture). But only PLC Connect object types can be deployed.
