Hi! I need to connect remote OPC server "B&R AR OPC Server DA2.04 AE1.03"
Developer write "you can read variable Winder State, Line Out"
I connect to that OPC server and find more than 9000 variables.
But I don't find variables Winder State and Line Out.
For my question developer send next table:

ItemName Value Name

GLOB_OPCWinderValues[1].pdo_2.value[1] Winder state

And write "we see client (Matricon OPC Explorer) can read ItemName via OPC but show only values".
This may depend on the settings of client's computer.

My question:
Can Matricon OPC Explorer read "Value Name" of ItemName?
If yes how to make it?

Hi,

Thanks for reaching out to us.

Ia m sorry but we are not sure why you are not able to see Winder State and Line Out item in OPC Explorer. OPC Explorer is the client and exposes all the items present in address space of the server so you need to get in touch with the Server Vendor to know why the items are not visible in client.

Also, OPC Explorer shows VQT i.e. Value, Quality and Timestamp for any item. I am not sure what are you referring as Value Name. Is it some item/tag or some attribute? Are you able to see this attribute in any other client?

ItemName is GLOB_OPCWinderValues[1].pdo_2.value[1] but ValueName is Winder state. I can see itemnames but I can't see valuenames. I think ValueName is description of item.
I don't know which OPC client can see description of item.
I have to prove with your help that matricon OPC Explorer can't see attribute the description of item.
