3-5-1 Basic Program for Temperature Control Unit
The contents of DM 0000 are written to the Temperature Control Unit as the set
point.
The process value is read from the Temperature Control Unit and written to DM
0001. If an error has occurred, however, the value written to DM 0001 will be
treated as an error code.

If the process value (contents of IR 001) is not
FFFF, IR 01600 is turned ON to indicate that
initialization has been completed.
If IR 01600 is ON, the contents of DM 0000 will
be written as the set point to IR 100.
If IR 01600 is ON, the contents of IR 001 will
be read to DM 0001 as the process value.
The contents of IR 001 is compared to FFFF to
confirm that the Temperature Control has com-
pleted initialization processing. (See note 3)
Note
1. Write a program for control loop 2 in the same way.
2. The contents of both DM 0000 and DM 0001 are four-digit BCD except that
an F in the leftmost digit is used to indicate negative values. The meaning of
