There are two ways to allocate I/O with CJ1.
- Automatic I/O Allocation When Power Is Turned ON
The I/O tables will be automatically created when the power is turned ON based on the information on the Units that are actually installed in PLCs. - User Allocation
The user creates the I/O tables using Programming Devices.
If a Unit connection check (using Programming Devices to verify that the Units registered in the I/O tables are actually present) or word reservations are required, the user must create the I/O tables or the user must transfer them to the CPU Unit.
