The Loop Controller's start mode at power ON can be specified from the CPU
Unit.
Explanation
Turn this bit from OFF to ON to restart
the Loop Controller. (The Loop Con-
troller will start initialization.)
Note: The bit will be reset to 0 (OFF)
automatically when initialization is
completed.
When this bit is set to 1 (ON), the
Loop Controller's "start mode at power
ON" will be hot start mode (as a com-
mand from the CPU Unit to the Loop
Controller.)
This bit is effective only when
ITEM018 of the System Control block
(block model 000) is set to 3 (com-
mand from CPU Unit.)
Note: If bits A60901 and A60902 are
both ON at the same time, this bit
takes precedence and a hot start will
be performed.
When this bit is set to 1 (ON), the
Loop Controller's "start mode at power
ON" will be cold start mode (as a com-
mand from the CPU Unit to the Loop
Controller.)
This bit is effective only when
ITEM018 of the System Control block
(block model 000) is set to 3 (com-
mand from CPU Unit.)
Note: If bits A60901 and A60902 are
both ON at the same time, A60901
takes precedence and a hot start will
be performed.
Note When ITEM018 (Start Mode at Power ON) of the System Control block (block
model 000) has been set to "3: Command from CPU Unit," the Loop Controller
will not operate (including exchanging data with the CPU Unit) until the RDY
LED indicator goes ON and either A60901 or A60902 is set to 1 (ON).
