3.8.2 Optional Integration Start/Stop
[Procedure]
(1) To execute optional integration start/stop, write data to the D register in the table
below. The data type is integer.
D Register
D0302
Reference No.
40302
H No.
012D
Description
Optional integration start/stop
Relevant D registers:
D0011 to D0014
Effective Range
0: Stop
1: Start
Initial value of optional integration start/stop: 0 (stop)
NOTE
Optional integration start/stop can also be controlled by digital input. Once digital input is
performed, it is the only means for such control. Control via communication is no longer
possible until the power is turned off or remote reset is executed (see subsection 3.7.1).
However, for the PR300 with demand measuring function, digital input is used to release
the demand alarm. In this case, optional integration start/stop cannot be used.
