Integrating OPC Servers into 800xA
428 3BDS011222-510 B
Service Group
• Adapter Identity field:
The ProgID for the Adapter to be used by the Service Providers in this group.
Normally, no need to change.
• Allow Parallel Redundancy check box:
When this alternative is checked, parallel redundancy is allowed for this Service
Group. Parallel redundancy is only used when an OPC DA client requests it
explicitly. If this alternative is unchecked, fail-over redundancy will always be used
regardless of what the OPC DA client requests. The recommendation is to allow
parallel redundancy, unless there are other controller specific recommendations.
• Process Object Locking check box:
The Process Object Locking check box is used for enabling or disabling the
process object lock functionality locally for a service group. Disabling process
object locking for a service group is used for connectivities that do not use the
standard 800xA process object locking function. The recommendation is to leave
the check box as it was when opening the Special Configuration tab.
