*1: If the setting of the production inhibit time is shorter than the scan time of the module, the master node transmits data to the slave node
at the intervals of the module's scan.
*2: The setting of the production inhibit time must be the same in all bit strobe connections.

(1) Set a minimum time during which the slave node can
receive data. The master node transmits output

(1) Specify an interval of data transmissions from the
master node to the slave node.
(3) Setting of the set value = 1, i.e., the production
inhibit time = 0ms is inhibited.
