Note : I-xx represents a CAN input signal; O-xx represents a CNB output signal.
[xx] represents a logical bit.
CAUTION
The logical port and logical bit numbers are virtual port and bit numbers that enable programming
independent of board I/O addresses or board types.
For details, refer to API-DIO HELP available after installing API-PAC(W32).
