Relationships between API-PAC(W32) Logical Ports/Bits and
Connector Signal Pins
The following table lists the relationships between the connector signal pins and the logical port/bit
numbers used for I/O functions when applications are written with API-PAC(W32).
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).
