10.5 Digital Relay Outputs
P219 - Relay function 1 DO1 (Address ModBus 2219)
P221 - Relay function 2 DO2 (Address ModBus 2221)
P223 - Relay function 3 DO3 (Address ModBus 2223)

Various functions can be combined with the relay outputs by raising or lowering the relevant bit.
If I enable 2 functions, I will obtain the result of OR logic
Example: if bit 3 (Alarm1) and bit 4 (Alarm2) on DO1 are raised, this output will be active if Alarm1 or Alarm2 is active.
