OptoOPCServer Indirect (CONT) method unable to scan groov discrete outputs with On/Off-Time Totalizer features
Applies To:
OptoOPCServer
Versions Affected:
R10.5a to current
Symptoms:
When a groov discrete output configured with the On-Time or Off-Time Totalizer feature is added to an OPC client using the OptoOPCServer CONT scanner, the retrieved values are always empty.
Additionally, if I/O scanning is configured in PAC Display Configurator (Configure > Runtime > I/O Unit Tags) to be done through the control engine (indirect method) instead of scanning the I/O directly (default), retrieved values will also be empty in PAC Display.
Workaround:
Use the OptoOPCServer Direct (MMIO scanner to add digital outputs with features to an OPC client.
For PAC Display, use the default configuration (scan I/O directly) instead of scanning through the control engine.
For more information, review the OptoOPCServer User’s Guide (Form 1439).
