Posted 27 Mar 2018 Hello, I don't have much experience with OMRON PLCs, but here we go. I am using CX-Programmer version 9.1 There is machine in my factory which is running on Omron PLC and HMI. Operator has an option on the HMI to save and load programs. Basically there are 150 lines in memory for each program (example D10000 - D10150), there are 16 different programs. Problem is that operator is saying that some of those programs are corrupted and she can't save new programs there correctly. So I thought I would try to delete some of the lines from the memory to see if that could fix the problem, but I do not know how to do it. When I open memory area in PLC and go to monitor mode and get the data for ex. D10000 - D10150 and I write 0 into every box and then try to upload it to PLC but I can't. I don't understand why is the "Transfer to PLC" button grey. What are the requirements for the button to go active? Or what would be the right action here if I want to clear the specific area in the memory? Any assistance regarding this problem will be much appreciated.

Posted 27 Mar 2018 The Transfer To PLC and Transfer From PLC are Offline (Monitor OFF) functions. If you are Online and write a 0 in the box, then you have already written to that memory location in real time. Be sure to save all your memory first. 1 person likes this Share this post Link to post Share on other sites

I can not "Transfer to PLC" when i'm not in monitor mode, but I can "transfer from PLC". When I'm in monitor mode it does not let me write anything into any of the memory fields, they are all gray. Also it seems to be a pain in the *** to save the memory. It keeps crashing sometimes. Share this post Link to post Share on other sites
Posted 2 Apr 2018 You can only write to the PLC and transfer data when in monitor mode or program mode. Put the PLC in monitor mode on start up and all will be good - monitor mode is the same as run mode except you can write to it and do online program changes. Settings as attached and write to PLC. 1 person likes this Share this post Link to post Share on other sites
Posted 2 Apr 2018 Thank you! I am now able to modify the memory the way I want to. Thank you to both of you! Share this post Link to post Share on other sites
