Posted 10 Sep 2008 Maybe a stupid question, but I'd like to know if it is possible and how. I would like to make a copy of the PC setup, route table and other information stored in the PLC in case a PLC needs to be replaced. I've seen the new CX-Programmer has a PLC-backup tool which can do that job for me. But I was wondering if it is possible to read that memory area in the PLC's internal memory by using an IR. Omrons documentation says that it is located from 00000 to 0BFFF in the internal memory. I've tried to copy a block to E0_0 and further, but nothing but 0's are copied. Example program: MOVL &0 IR0 MOVR E0_0 IR1 FOR &32767 MOV ,IR0+ ,IR1+ NEXT Isn't it possible to read the configuration in the PLC internal memory by means of IR's. Or is there an other way.

Posted 11 Sep 2008 Routing tables can be uploaded using Integrator. The other stuff can be read, and saved in the program, from the memory section in the workspace. Share this post Link to post Share on other sites
