IF16 I Ch1 Count Stuck

[tushar.matrix 1]

Hi All , Wish you all Happy New Yer 2011, God bless you all & your wishes come true. I am doing SAT of one project, There is CLx processor and analog Input card IF16I which is configured as Float differantioal , Ch0 is for Weighing scale A, Ch1 is for Weighing scale B, both scales gives 4-20 ma form their tramsitters. Scaling is as 4ma = 0 count & 20 :: 32767 counts . The program uses standard SCALING block downloaded for rockwell, which calculates 0% offest and 100% as the scale wights CAN (empty 0% and full 100%). Now Thescale A: Ch0 is ok . but the ch1 count value is lached to count 33998 , when i opened knife switches it is still there , Iwas expecting 0 or - 0.000 data there in ch1.data. I can not reset the data ebven i tried removing card from that slot. Still data lached there. My obsevarion is when i removed card Ch0 shows same count 33998. Is there anything to do with RTN terminal and iRTN ?? Please suggest /Advice.
