This register contains the lower user limit value. The resistance/temperature value calculated by the
I/O module is compared to the limiting value entered by the user. If the resistance/temperature
value calculated by the I/O module falls below the value entered here, the I/O modules signals a
limiting value underrange.
The scaling of the value to be entered here depends on the sensor type set.
Diagnostics for the lower user limit value is enabled if bit 10 in register 35 is set.
