OPC EXPERT FREE VERSION

OPC Expert Free Version times out after 4 hours.  After this period, simply stop OPC Expert and start it again to receive another 4 hours, you can do this as many times as you need.  This affects all OPC Expert executables including archiving, bridging, redundancy, tunneling (Mimic), etc.
Note: OPC Expert Pro does not have this 4-hour time limitation and continues working.

OPC Expert enables Excel to receive real-time and historical OPC data.  OPC Expert uses an add-in and an RTD (Real-Time Data) server to handle the task.  OPC Expert Free Version imposes a few limitations:

  • Time: Excel connectivity times out after 1 hour.  After this period, you must close Excel and open it again.  You will then get another hour… and you can do this as many times as you need.  OPC Expert Pro does not have a time limit.
  • Real-time data: Excel is limited to read and write to 15 items.  OPC Expert Pro enables Excel to read and write as many items as necessary.
  • Historical data: Using OPC UA HA (or OPC HDA), Excel can retrieve 100 values for each item.  OPC Expert Pro enables Excel to retrieve as many items as necessary.

Note: OPC Expert Pro does not impose the above limitations of time and items.
