[Example 2]
When the Input 1_Input range is 0 to 400 °C and the Input 1_Setting limiter high
is 400 °C, changing the Input 1_Input range high to 800 °C will not affect the
setting limiter value. In this case the Input 1_Setting limiter high remains 400 °C.
When a wider setting range of the Set value (SV) is required according to the
extended input range, change the setting limiter value accordingly.

To display “Input 2_Setting limiter high”, choose “2-loop control/Differential
temperature control” or “Cascade control” in Function block No. 58: Select
function for Input 2 (Engineering mode).
Refer to “4. Parameters that are Initialized/Modified when Setting is Changed”
for the parameters that are automatically converted when the Input 2_Setting
limiter high is changed.
