according to the setting of the input signal error detection
function.
An input signal error is occurring.
The channel where the input signal error has occurred fits in
A value fits in

This alarm code is stored when an input signal error is detected
according to the setting of the input signal error detection
extension function.
Description and cause of error
Description and cause of alarm
indicates that the alarm status is as follows:
indicates that the detection status is as follows:
Set No request (0) or Clear request (1) in CH
Integrated flow amount clear request (Un\G1372 to
. Un\G1375).
When the scaling value (digital operation value)
returns to the one within the setting range, the
corresponding bit of Warning output flag (Process
.
alarm) (Un\G50) and Warning output signal (X8)
turn off.
The alarm code can be cleared by turning off, on,
and off Error clear request (YF) after the scaling
value (digital operation value) returns to the one
within the setting range.
.
The corresponding bit of Input signal error
detection flag (Un\G49) and Input signal error
detection signal (XC) turn off by turning off, on,
.
and off Error clear request (YF) after the analog
input value returns to the one within the setting
range.
