OPC Items

OPC Items are tags that define how values are exchanged to and from an OPC Server. You must configure these parameters before adding an OPC Item:

  • OPC Client
  • OPC Server
  • OPC Group

To view and configure OPC items, navigate to Configuration > OPC > OPC Items.

You can use these options on the OPC Items screen:

  • Add: Allows you to create a new OPC item.
  • Edit: Allows you to modify the existing OPC items.
  • Delete: Allows you to delete the existing OPC items.

These types of OPC Items can be used to record different values from PLCs:

  • Machine Event: Used to record the status of a machine (stopped or running).
  • Counter: Used to record production counts and scrap counts.
  • Parameter: Used to record process parameters.
  • Digital: Used to record machine events or Boolean values.
  • Text: Used to record text based values.
  • Meter: Used to record energy meter readings.
