4. Devices in Detail
This chapter explains how numeric values are handled in the PLC as well as the roles and functions of various built-in
devices including I/O relays, auxiliary relays, state relays, counters and data registers.
The following content provides a basis for handling the PLC.
4.1 Device Number List
Device numbers are assigned as shown below.
For input relay numbers and output relay numbers when I/O extension equipment and special extension equipment
are connected to the PLC main unit, refer to the Hardware Edition.
