ObjectType Description
Variable [IOBitIdentifier]
[IOBitIdentifier] indicates I/O port is including multiple I/O signals, and there are this Variable node exists for each bit of the I/O signal.
Value=TRUE means I/O signal is ON, FALSE means I/O signal is OFF.
Variable [IOByteIdentifier]
[IOByteIdentifier], like [IOBitIdentifier], indicates that the I/O port includes multiple I/O signals. This variable node exists for each byte of the I/O signal. When the Value is converted into a binary bit string, the port of the number(0~) of the bit that becomes 1 means ON in the I/0 signal, and the port of the number of the bit that becomes 0 means OFF in the I/O signal.
Variable [IOWordIdentifier]
[IOByteIdentifier], like [IOByteIdentifier] and [IOBitIdentifier], indicates that the I/O port includes multiple I/O signals. This variable node exists for each word of the I/O signal. When the Value is converted into a binary bit string, the port of the number(0~) of the bit that becomes 1 means ON in the I/O signal, and the port of the number of the bit that becomes 0 means OFF in the I/O signal.
