pzhuproax.ca Posted May 22, 2020 Share Posted May 22, 2020 It looks like only I variables are retentive. But I variables are all the motor parameters. I am using CK3E alone with an OMRON NB HMI. For a proper project, i need to use a lot of retentive variables in the program. How can i get these variables? Thanks, Link to comment Share on other sites More sharing options...
Alex Anikstein Posted May 22, 2020 Share Posted May 22, 2020 The easiest way to do this may be to add them to pp_custom_save.tpl. If you simply list the names of your variables there, build and download the project, and then issue a "save" or "fsave", they should be saved just like an I Variable would be. That said, are these parameters that you need to be able to save, or just parameters that you want initialized to a specific value? If you simply declare and set them in your project (such as by putting "GLOBAL MyVar = 5" in a file in your "Global Includes" folder), that would also allow them to initialize with your pre-set values.

pzhuproax.ca Posted May 25, 2020 Author Share Posted May 25, 2020 thank you for your reply. I need the parameters saved every time when I change from the HMI. Link to comment Share on other sites More sharing options...

I am using an Omron HMI to communicate with CK3E controller through Modbus Tcp. And I just noticed that save command can only be sent from IDE. Is there any other way I can send the save command through the HMI or plc program in Ppmac? thanks, Link to comment Share on other sites More sharing options...
