i would be so grateful if you could explain exactly how the OPC DA server performs when enabling it in the workstationST:
- In the OPC DA server tab, does the "Client Driven variable" means the variable of the workstation which are held by the OPC?
- does it copy directly the EGD data?
- if a variable is shared from an other device through the OPC, it would be copied directly in the EGD?
- how data is provided to other OPC clients or external servers?
Thanks in advance.
