how can i compare 2 data files...IE f8 to f9. and if they are different write one to the other.
I am using an omnii com module to convert df1 to modbus ascii. I have a polling table setup to convert
f8.0 to 40100/40101
f8.1 to 40102/40103 etc
when i write back from modbus ascii to df1 i cant write to the same register becuase it will be over written so what i want to do i write
40100/10101 to f9.0
40102/40103 to f9.1 etc
and then compare the whole f9 data file to the f8 datat file. If they are not the same then overwrite f8 with f9. thanks
