STEP 1 -
Host sends following register contents
to initiate Force Physical Input 1 ON ( Assumed that default
password of all spaces is active).
41417 = 2020 hex (Password Hi)
41418 = 2020 hex (Password Lo)
41419 = 0 (Reserved)
41420 = 0008 hex (Select Bit to Change)
41421 = 0008 hex ( Place Bit in Forced State).
41422 = 0008 hex ( Send State of Force = 1)
EXAMPLE 2 - Force Input 4 to a State of 1 and Then to a Force State of 0, and
Then to a Normal State.

C
The relay forces the Input Status of Physical Input 4 to be a
value of 1 Forced. A Modbus response will be returned to the host
indicating that the command has been accepted.
