Manual
Version 1.1.0
4.3.10.2 S5-FB250 Format
With the setting “Ni1000 (TK6180, DIN 43760)” and activated S5-FB250 format,
the I/O module converts the measured resistance values of Ni1000 sensors
(DIN 43760) into temperature values and outputs the conversion results.
The temperature values are displayed at a resolution of 1 digit per 0.05 °C.
The status information is depicted in bit 0 to bit 2 and the digitalized measured
value in bit 3 to 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 “Diagnostics” > „Behavior in
the Event of an Error“)
3) When underrange / overrange limit is ON (see section “Diagnostics” > „Behavior in the Event
of an Error“)
4) Status information:
X: Not used,
F: Short circuit, wire break,
Ü: Underrange, overrange
