parameter access in s7-300 with 22-comm-p

can any body help me to Reading/writting drive pf40 parameters through profibus network.

i have S7-300 plc. cpu 315-2dp connected in profibus via 22-comm-p and power flex 40 drive.

in my hardware configuration i have configured the parameter access module.

i have written the programe to read the parameter

request--->response -----> 0---->0

when send read parameter 22. the following response i am getting. i think this not correct.

request word 1 = 2#0001_0000_0001_0110

response word 1= 2#0001_0000_0111_0110

help me to read the correct parameter.

i have found that the bytes were getting swapped. so changed the jumper J3 in 22-comm-p to lower position then the problem got solved.
