Description and cause
The values set in CH Process alarm upper upper
limit value to CH Process alarm lower lower limit
value do not satisfy the following condition:
Upper upper limit value  Upper lower limit value 
Lower upper limit value  Lower lower limit value
 indicates that the set values are as follows:
1: Process alarm lower lower limit value > Process
alarm lower upper limit value
2: Process alarm lower upper limit value > Process
alarm upper lower limit value
3: Process alarm upper lower limit value > Process
alarm upper upper limit value
A value other than Enable (0) and Disable (1) is set
in CH Warning output setting (Rate alarm).
A value other than 1 to 32000 is set in CH Rate
alarm warning detection cycle setting.
CH Rate alarm upper limit value and CH Rate
alarm lower limit value are set as Lower limit value 
Upper limit value.
A value out of the range is set in CH Input signal
error detection setting.
A value other than 0 to 250 is set in CH Input
signal error detection lower limit setting value or
CH Input signal error detection upper limit setting
value.
Simple disconnection detection is set in CH Input
signal error detection setting, and the value set in
CH Input range setting is other than the following:
• 4 to 20mA (extended mode) (AH)
• 1 to 5V (extended mode) (BH)
A value out of the range is set in CH Logging
enable/disable setting.
A value out of the range is set in CH Logging cycle
setting value and/or CH Logging cycle unit setting.
CH Logging cycle setting value and CH Logging
cycle unit setting are set so that the set logging cycle
falls below the conversion cycle.
A value other than Digital output value (0) and Digital
operation value (1) is set in CH Logging data
setting.
A value out of the range of "1 to (the value set in
CH Logging data points setting)  100" is set in
CH Post-trigger logging points.
A value out of the range is set in CH Level trigger
condition setting.
A value other than 0 to 9999 is set in CH Trigger
data.
A value other than Enable (0) and Disable (1) is set
in CH Loading interrupt enable/disable setting.
A value out of the range of "1 to (the value set in
CH Logging data points setting)" is set in CH
Logging read points setting value.
A value other than 0 to 900 is set in CH Logging
data points setting.
The total of values set in CH Logging data points
setting is beyond 900.
Action
Set CH Process alarm upper upper limit value to
CH Process alarm lower lower limit value so that
the values satisfy the following condition:
Upper upper limit value  Upper lower limit value 
Lower upper limit value  Lower lower limit value
Set CH Warning output setting (Rate alarm) to
Enable (0) or Disable (1).
Set CH Rate alarm warning detection cycle setting
to 1 to 32000.
Set CH Rate alarm upper limit value and CH
Rate alarm lower limit value as Lower limit value <
Upper limit value.
Set CH Input signal error detection setting to
Disable (0) to Simple disconnection detection (4).
Set CH Input signal error detection lower limit
setting value or CH Input signal error detection
upper limit setting value to 0 to 250.
For channels where simple disconnection detection
is performed using the input signal error detection
function, set CH Input range setting to either of the
following:
• 4 to 20mA (extended mode) (AH)
• 1 to 5V (extended mode) (BH)
■Normal mode (low speed: 20s/CH)
Set CH Logging enable/disable setting to Normal
logging (0) or Disable (1).
■Normal mode (high speed: 1s/CH)
Set CH Logging enable/disable setting to High
speed continuous logging (2) or Disable (1).
Set one or both of CH Logging cycle setting value
and CH Logging cycle unit setting to the values
within the range.
Set CH Logging cycle setting value and CH
Logging cycle unit setting so that the logging cycle is
not less than the conversion cycle of the object to be
logged.
Set CH Logging data setting to Digital output value
(0) or Digital operation value (1).
Set CH Post-trigger logging points to a value
within the range of "1 to (the value set in CH
Logging data points setting)  100".
Set CH Level trigger condition setting to Disable
(0) to Process alarm (upper limit warning/lower limit
warning) (6).
Set CH Trigger data to 0 to 9999.
Set CH Loading interrupt enable/disable setting to
Enable (0) or Disable (1).
Set CH Logging read points setting value to a
value within the range of "1 to (the value set in CH
Logging data points setting)".
Set CH Logging data points setting to 0 to 900.
Set values so that the total of values set in CH
Logging data points setting of all channels becomes
900 or less.
