2-7 IOTC(––)
The following words are allocated to the Temperature Control Unit in these ex-
amples:
Input word = IR 001
Output word = IR 100
The following procedure would be used to write a set point of 100 °C for loop 1
and then monitor the process value for loop 1.
1. Start by monitoring IR 001 and IR 100 on the Programming Console.
c100 c001
0000 0000
2. Write "C071" to the output word to specify setting the set point and reading
the process value.
"C071" will be written to the input word to acknowledge the command.
c100 c001
C071 C071
3. Write the set point for loop 1 (100 °C) to the output word.
The process value for loop 1 will be written to the input word, indicating that
the write operation has been completed.
c100 c001
0100 0025
Note If the contents of IR 100 are left unchanged, the process value in
IR 001 will be updated every 500 ms.
The following procedure would be used to switch to RUN status for all loops.
1. Start by monitoring IR 001 and IR 1000 on the Programming Console.

2. Write "CCDA" to the output word to specify RUN status for all loops.
"CCDA" will be written to the input word to acknowledge the command.
c100 c001

The IOTC(––) instruction is supported by CX-Programmer version 2.0 or later
and CPU Unit lot number 0160 or later. The SYSMAC Support Software can also
be used by uploading the expansion instructions from a CPU Unit with a lot num-
ber of 0160 or later.
