Ni120 (Minco)

With the setting "Ni120 (Minco)" and activated Siemens format, the I/O module
converts the resistance measured values of Ni120 sensors (Minco) and outputs
them as temperature values.
The temperature values are displayed at a resolution of 1 digit per 0.5 °C.
The status information is depicted in bit 0 ... bit 2 and the digitalized measured
value in bit 3 ... bit 15.

1) Temperature values below 0 °C are represented in two's complement binary.
2) When short circuit and wire break monitoring is ON (see section "Behavior in the Event of an
Error")
3) When underrange / overrange limit is ON (see section "Behavior in the Event of an Error")
