Use
When current/voltage pulse output is not used for control output, it can be used for
retransmission output.
When retransmission output terminal is not used for retransmission output, it can be used
for optional control output. The current output range can be changed.
For control output setting, set the control mode (CTLM) and the control type (CNT), then
set the output terminal and output type in the output type selection (OT).
