5.1.3. Assignment of outputs (relay and current) to the device
During configuration, the relays and current outputs should be assigned to the field devices and to their variables (PV, SV, TV, QV):
Value has a positive sign (for summation)
Value has a negative sign (for differential measurement)
Values from devices marked this way will be averaged
The above settings can be changed using
Assignment of device SE380-1 to the relay R_IN_1 in the MultiCONT should be performed as below:
1: SE380-1
2: SE380-2
3: SE360-1

Relay R_IN_1 is controlled by
the average of the measured
values of SE380-1, SE380-2
and SE360-1
Important: If there are more than one devices (sources) assigned to a relay (difference or average) then those devices should be programmed to
measure the same parameter (DIST, LEV, ...) in the same unit (m, ft, inch, ...)
Otherwise error message (Program) will appear. See 5.7, 5.8 and 6.
