Posted 9 Sep 2020 I have moved this from the Sysmac / Sysmac Studio forum to the general Omron forum as this is not a Sysmac PLC. Whenever I encounter a situation like this, I look to go back to something that works. Assuming you have a backup of the programs, setting, and Data, clear all the PLC setting from the CX Programmer menus. Sorry, I am not near a PC, but one of the menus has something to the effect of Clear All Memory. See if this clears the error. If it does, start to transfer your project back to see what makes it stop working. Does the PLC have an Ethernet/IP connection to any devices such as IO, inverter, vision, etc? 1 person likes this Share this post Link to post Share on other sites
