The SRD991 sends during normal operation its actual Position-Actual-
Value
1)
back to the control system.
If, however, “Simulate” is released in the SRD and in addition via communi-
cation Simulate is activated, then a simulation value coming from the control
system is sent back as an actual value to the control system. In this way
within the control system, e.g. the reaction to specific valve adjustments can
be tested without having to adjust the valve – the SRD regulates toward the
”accurate” setpoint value.
For further information about the Simulate see TI EVE0105 Q.
