CH1 Upper limit setting limiter
Set the upper limit value of the set value (SV).
■Buffer memory address
The following table shows the buffer memory address of this area.
Buffer memory name
CH Upper limit setting limiter
CH Upper limit setting limiter (If using FX3 allocation mode)
■Setting range
The settings range depends on the type of inputs used.
• Internal temperature inputs: Lower limit setting limiter +1 to input range upper limit
• Internal micro voltage inputs: Lower limit setting limiter +1 to scaling range upper limit
• External inputs: Lower limit setting limiter +1 to external input range upper limit
Configure the settings that satisfy the following conditions.
• 'CH1 Lower limit setting limiter' (Un\G512) < 'CH1 Upper limit setting limiter' (Un\G511)
When the above conditions are not satisfied, CH Upper/lower limit setting limiter error (error code: 1A1H) occurs.

Input lower limit
(1) 'CH1 Lower limit setting limiter' (Un\G512)
(2) 'CH1 Upper limit setting limiter' (Un\G511)
■Setting unit
The value to be set differs depending on the value stored in 'CH1 Decimal point position' (Un\G400). (Page 128 CH1
Decimal point position)
• No decimal point (0): Set a value in increments of 1 (or digit).
• If there is 1 digit (1) past the decimal point: Set a value (the value multiplied by 10) in increments of 0.1 ().
■Default value
The default value is 1300.
CH1 Lower limit setting limiter
Set the lower limit value of the set value (SV).
■Buffer memory address
The following table shows the buffer memory address of this area.
