Is It Necessary To Create I/O Tables When Using CJ1 PLCs?

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.
