• When the set value is “0”, the input bit function is not used and the default input
is used. The following shows the default input of each internal contact:
Internal Contact 1: digital input (DI) 1
Internal Contact 2: digital input (DI) 2
Internal Contact 3: digital input (DI) 3
Internal Contact 4: digital input (DI) 4
Internal Contact 5: OFF status
• In the input bit function, the logical operations (AND, OR) of each of internal
contacts 1 to 5 are combined. In input bit functions 1 to 4, the combination of the
logical operations may vary. The following shows one logical operation:
Logical AND Logical OR
OFF and OFF = OFF OFF or OFF = OFF
ON and OFF = OFF ON or OFF = ON
ON and ON = ON ON or ON = ON
• “OFF” is “contact open (OPEN)” or “0” when expressed using the numerical
value.
• “ON” is “contact close (CLOSE)” or “1” when expressed using the numerical
value.
