(31)CH Upper limit setting limiter (Un\G55, Un\G87, Un\G119, Un\G151)
CH Lower limit setting limiter (Un\G56, Un\G88, Un\G120, Un\G152)
Upper/lower limit value of the set value (SV) can be set.
(a) Setting range
The setting range is identical to the temperature measurement range of the set input range. ( Page 96,
Section 3.4.2 (12))
The setting should meet the following conditions.
•CH Lower limit setting limiter < CH Upper limit setting limiter
If the above conditions are not met, a write data error (error code: 5
H
) occurs.
(b) Setting unit
The value to be set differs depending on the stored value in CH Decimal point position (Un\G1 to Un\G4).
( Page 86, Section 3.4.2 (2))
• No decimal place (0): Set a value in 1°C ( or digit) unit.
• One decimal place (1): Set a value in 0.1°C ( ) unit (tenfold value).
(c) Default value
A default value differs depending on modules to be used.
