2-1-9. Setup Data Read into Temperature Control Unit
Setup data (warning mode, warning hysteresis range) configured in step 4 are assigned
to special I/O unit assignment DM area as the initial setup data of the unit for 10 CHs
based on the unit number. Thus if you changed the setting value by following the step 4,
you have to set special I/O unit restart flag to OFF -> ON -> OFF based on the following
table to restart the unit and read the setting value into the unit. In this example unit
number 0 is used, thus A50200 must be set to OFF -> ON -> OFF.
Special auxiliary relay restarts A50200 when turned ON and then OFF again.

2-1-10. Configuring Control Data for Operation
Configuration of control data for operation (warning, control frequency, proportional
band, integral time) are made through assigned data of special I/O unit assignment
DM area.
Note that exchange of control data for operation is performed for every scanning at
I/O refreshing of the CPU unit in the order of OUT (CPU unit -> this unit) then IN (this
unit -> CPU unit).
In this example, set DM20010 to 0010 (BCD: set Warning 1 value to 10 deg. C) and
DM20011 to 0020 (BCD: set Warning 2 value to 20 deg. C). Other values are set to
default values.
DM20010=#0010
DM20011=#0020
