(3) End code
When the end code is “00”, this indicates normal completion of the
command. Otherwise, the command could not be processed. For
details on end codes, see “Response frame” on page 4-3.
(4) Precautions
·
Even though alarms 1 and 2 are not displayed on the controller’s dis-
play, they are all functional in communications.
·
When the controller has moved to setting area 1, the previous state is
held. “Setting area 1” is where the initial setting, communications
setting, advanced function setting and calibration levels are grouped
together.
This command writes the set point, alarm values 1 and 2, proportional
band, integral time, derivative time, temperature input shift values and
heater burnout detection.

F
Alarm values 1 and 2
When “alarm 1 type” is set to one of “upper/lower-limit alarm,” “upper/
lower-limit range alarm” or “upper/lower-limit alarm with standby
sequence”, “alarm value 1” is disabled as the upper and lower limits of
the alarm are set independently. “Upper-limit alarm value 1” and “low-
er-limit alarm value 1” become the alarm set values.
