Fatek FBs Shift Register

Hello Guys

I m using fatek since 3 years and its been a good experience. I use function 6 shift register with bit read funtion 40 and get them worked with no trouble. N is to defined on bit read, but now i want to give the counts more than 31 and the bit read is not accepting it. So, is there anyway that i can give value of e.g 100 to N in bit read?

Any help would be highly appreciated.

Thanks
