I have a HMI/SCADA Cimplicity licence of 150 points, and I have a lot of setpoint that the operator can modify. I do not have the choice but to write all my setpoints within an array of REAL or INT, and even BOOL for commands.

I want to write the sepoints to a Versamax PLC (CPUE05).

I created virtual points in order to read/write in the arrays. Reading works well. But I cannot write to the PLC. The Value in the virtual point is updated, but it seems that the raw value of the array doesn't update and, of course, the value in the PLC doesn't update either.

In my Point Properties window, under the "virtual" tab, the calculation method is "Equation w/Override" and the expression is (for example) "FIT149_WR_REAL[2]" which is the third (0,1,2,...) REAL element of the array FIT149_WR_REAL.

What can I do to make the data read by the PLC ?

Ragards,

The CPUE05 does not understand virtual points, it only knows PLC addresses like %R23. BTW, what protocol are you using?

I fixed my issue. Thank you for the interest to my topic.

The problem wasn't with the Versamax PLC. I was able to read data to PLC from arrays, but not to write.

I had to used some scripting to fix my issue.

Thanks again !
