a PID number.
• Status switch 1 (Operation by keystroke or via communication is enabled depending
on the conditions.)

*2: PID number can be switched by keystroke or via communication when all contact inputs of
PN.B0 to PN.B3 are turned of
f.
*3: PID number cannot be switched by keystroke or via communication when any contact input of
PN.B0 to PN.B3 is turned on.
*4: The contact input is turned off when the bit of PID number is not assigned to the contact input.
• Status switch 2 (Operation by keystroke or via communication is disabled.)
