The starting DM Area word (m) for a Special I/O Unit is:
m = 20000 + (100 × unit number)
The Temperature Control Unit's Operating Parameters are set in the DM
words allocated to the Temperature Control Unit as a Special I/O Unit. Operat-
ing Parameters include the Alarm SVs, Control Periods, Proportional Bands,
Integral Times, and other parameters.
Operating Parameters are exchanged each cycle during the I/O refresh
period. Input data is transferred from the Temperature Control Unit to the CPU
Unit and output data is transferred from the CPU Unit to the Temperature Con-
trol Unit.
Input data is
transferred from the
Temperature Control
Unit to the CPU Unit
and output data is
transferred from the
:
CPU Unit to the
Temperature Control
Unit each cycle during
:
1. Loops 3 and 4 are applicable to Temperature Control Units with four control
loops only. If a Temperature Control Unit with two control loops is being
used, the settings for loops 3 and 4 will not be used and will be ineffective
even if they are set.
2. The Special I/O Unit Area words that are allocated to the Temperature
Control Unit in the DM Area are determined by the setting of the unit num-
ber switch on the front panel of the Unit. Refer to 2-3-3 Unit Number
Switches for details on the method used to set the unit number switch.
3. If two or more Special I/O Units are assigned the same unit number, a
"UNIT No. DPL ERR" error (in the Programming Console) will be generat-
ed (A40113 will turn ON) and the PLC will not operate.
