4. Mount and wire the Unit, referring to 1-2-2 Mounting the Unit .
5. Turn ON the power supply to the PLC.
Creating I/O Tables
There two different methods that can be used to create I/O tables with the CJ-
series PLCs. Refer to the
CJ Series Programmable Controllers Operation
Manual (W393) for details.
Automation Creation The PLC can be set to automatically create I/O tables at startup. If this is
done, the user does not need to create the I/O tables.
Use-set I/O Tables After turning ON the PLC, create the I/O tables. The key sequence for creating
I/O tables from a Programming Console is shown below.
Program
In this example, the process value (PV) output to the words allocated in the
CIO Area to the Temperature Control Unit as a Special I/O Unit are stored in
memory for four loops. The words n+3, n+4, n+13, and n+14 will contain the
PV and are CIO 2013, CIO 2014, CIO 2023, and CIO 2024 in this example.
Note 1. Determined by the unit number that is set for the Temperature Control Unit
as a Special I/O Unit. (Refer to
2-3-3 Unit Number Switches .)
2. Set as desired in programming.
3. Sensor Error Flags are allocated to bit 14 of n+8, n+9, n+18, and n+19.
(Refer to
Four-loop Units on page 33.)
