2. Set the Communications Main Setting Number parameter [P25] to the de-
fault value (0: Automatic assignment). The EJ1 will create communications
frames for the MVs for the maximum number of channels (i.e., four chan-
nels for the TC4 Unit). The Communications Main Setting Number param-
eter of the G3PW is set to specify automatic assignment, so the channel
number for the MV will be the same as the communications unit number
for each channel.
Communications Main Setting Number: Automatic Assignment
1) Communications frames for the MV for all channels are sent from the EJ1 to
the G3PW according to the unit numbers. User programming is not required.
