4.1.3 Pt100 with Status Information for S5-FB250 in the Data
Word
The 750-461/000-200 version outputs the resistance values of the Pt100 sensors
directly. The status information is depicted in bit 0 to bit 2 and the digitalized
measured value in bit 3 to bit 14. When an S5 system is used as the master
controller, this data can be directly evaluated using the FB250 function block.
