MikhailModeratorI am sure that I can write with this method: IOPCSyncIO::Write
To do this, the OPC driver have to be redesigned using another OPC client library.
This is possible. However, I suppose that it would be much cheaper if the OPC server developer supports WriteVQT.What communication protocol do you use?
Are there alternative OPC servers?
Can you find OPC UA server? OPC UA .NET API is officially free.

MikhailModeratorWhat recommendations are you referring to?
First of all, copy here your actual communication log where we can see sending a command.

MikhailModeratorAlso, is there a way of recording only one condition of the event?

MikhailModeratorHi,
Event color depends on status color of the input channel. I mean you should change colors of Off-On values.
Create your own record in the Units table, for example,
Normal; Alarm; –
And use formulas for setting the status of the input channel:
Cnl; Cnl > 0 ? 114 : 13
MikhailModeratorHennie, you may try the above recommendations.
