udhaya Posted July 27, 2013 Report Posted July 27, 2013 Freinds I'm using the c200hx-cpu42 plc from that i took backup by using cx-programmer v9.2 in that @hms as wrongly programmed i had attached the file,due to that sequence is not working properly. one more problem with this i moved 1555 value to the *DM5000,after execution of this mov instruction the 1555 has been moved to the all dm address from DM0 to DM4120 and that *dm5000 is not used anywhere in the instruction, i cant able to restore that original value and i suffering lot.. can anyone please help me...........
PdL Posted July 27, 2013 Report Posted July 27, 2013 Sounds to me some indirect addressing is being used in your logic. Have you checked for DM1555 being used anywhere in your logic? Also mght want to check for DM0 being used as range base.
udhaya Posted July 28, 2013 Author Report Posted July 28, 2013 No i didn't used DM1555 anywhere in the program, but Range Selection i don't know
