4.4
Receiving and Forwarding of I/O Signals Necessary for Operation
I/O port is an area that data is sent and received between this product and external signals via the
interface.
One port can exchange data for one contact (1 bit).
Data is exchanged via PIOs (24V I/Os) or over a Field Network.
Either a PIO or Field Network can connect to each port at a time.
Whether to use PIO or Field Network is set by a parameter.
Refer to Section 3.3.4 for the I/O interface.
For the Field Network Interface, refer to each operation manual.
