7 Control
In addition to the process controller status word, bit 8 of the device status word,
P 702[0] - MON_State, will be set when the setpoint is reached. P 2679[0] - CON_
PRC_RefReached can be used to configure the “Reference value attained” window
for this purpose. Bit 8 will be set to TRUE if the process controller’s deviation is less
than 50 % of the configured “Reference value attained” window.
7.10.2.2 Reference values
The process control circuit setpoint can be selected via pre-defined setpoint sources.
