NOTE
The common types of Boolean signals are the dry contact point type, OC type, voltage type, and current
l
type.
All the monitoring ports for Boolean signals support Boolean signals of the dry contact point type and
l
OC type.
Ports S13 - S16 and S29 - S32 support Boolean signals of the voltage type.
l
lists the valid values of Boolean signals of the voltage type.
lists the meanings of the terminals of the monitoring port for Boolean signals.
NOTE
You can set the DIP switches SW12A, SW12B, SW24A, and SW24B to choose whether to use the
monitoring port for Boolean signals. For details, see
