command processing for setpoint values, responsvalue question.

command processing for setpoint values, responsvalue question.

Hi

I'm using zenon energy edition 8.1 using IEC 60870 driver to a RTU.
To write analog setponit values to the RTU, I'm using command processing, one setpoint variable T50 and responsevariable T36.
As soon as the T50 value is recieved in the RTU, its looped back to a T36 variable for indication of actual setpoint.
The command processing dialog is called up from a numeric field, under write set value via "Command Processing", this is working as expected.
Now to my question, when using the checkbox "propose current value", zenon is taking the current value of the commandvariable T50 and put it in the numeric inputfield, as a "startvalue", however, I would like to have the responsvalue copied there instead, is that possible?

My problem is that setpoint can be changed from other systems also, zenon is not the only scada.
If I restart Zenon, the T50 variable is zero, so proposed value will be zero, this mayby can be fixeed with variable remanence, but if other system is modifying setpoint in the RTU, proposed value in zenon is not relevant anymore, thats why I think responsvalue would be better as propose current value.
