The Temperature Control Unit is allocated 10 words in the IR or CIO Area ac-
cording to the unit number switch setting on the front of the Unit. These words
are used as an I/O refresh data area. The IR or CIO Area words used by the Tem-
perature Control Unit are refreshed each I/O refresh scan of the CPU Unit.
During PC I/O refresh,
each scan is executed for
the outputs (PC to Temper-
ature Control Unit) followed
by the inputs (Temperature
Control Unit to PC).
During PC I/O refresh, each
scan is executed for the outputs
(PC to Temperature Control Unit)
followed by the inputs (Tempera-
ture Control Unit to PC).
Note A Duplicate I/O Unit error occurs if the set Unit number corresponds to the num-
ber of an existing Special I/O Unit.
The data allocated to each IR word due to the Unit number setting is determined
by the setting of SW2-1 on the front of the Unit.
