FP0_RTD_INT
This function block reads RTD (Resistance Temperature Detector) data on the input channels of
Description
the FP0-RTD6 unit. The RTD unit converts the data to digital data transferred to the output
channels as INTEGER values.
For the RTD input data you can use the following devices: Pt100 (according to IEC751), Pt1000
(according to IEC751), Ni1000 (according to DIN43760) or a resitor.

The online help only provides a short overview of DIP switch settings and wiring. For technical
information, please refer to the manual FP0 RTD Unit ACGM0159 on your FPWIN Pro installation

PLC types
Input range setting by DIP switches
The DIP switches configure the analog channels. You set the measurement range (type of sensor
or resistor) and the sampling cycle.
The following switch settings are read once when the control unit is turned ON. Changes will not be
reflected if they are performed while the control unit is turned ON.

Reads analog data from the FP0-RTD6 unit
Between power ON and the first valid conversion data, the digital value
will be 8191 or 16383. When programming, be sure not to use the data
obtained during this period.
When the RTD is broken, the digital value will change to 8191 or 16383.
When programming avoid any risks resulting from a broken RTD. A
broken RTD needs to be replaced.
