(2) Data Code
Set the data code to "02" only when writing alarm value 2. In all other
cases, set to "01."
(3) Read Value
For details on the read value ranges, see SECTION 3 Communications
Data for CompoWay/F and SYSWAY.
(4) Precautions
● Alarm Values 1 and 2
When the alarm 1 type is set to "upper and lower-limit alarm," "upper
and lower-limit range alarm," or "upper and lower-limit alarm with
standby sequence," the alarm's upper and lower limits are set indepen-
dently. The "alarm value 1" setting is disabled and the "alarm value
upper limit 1" and "alarm value lower limit 1" settings are used as the
alarm set values.
For this reason, when "upper/lower-limit alarm" is set, the value of
"alarm value upper limit 1" and not "alarm value 1" is the value read by
communications. The same applies to "alarm value 2."
● Temperature Input Shift Value
When the 2-point shift method is used, the Temperature Input Shift
parameter is disabled and the Upper Limit Temperature Input Shift
Value and Lower Limit Temperature Input Shift Value parameters are
enabled as the temperature input shift set values. For this reason, when
2-point shift method is being used, the Upper Limit Temperature Input
Shift Value parameter is read and not the Temperature Input Shift
parameter.
