Posted 26 Apr 2022 I am being new in GX works 2 need your help in executing TON timer. PLC is FX3U26MR-E. When I download structured ladder program with TON the PLC goes into error. Compiling successfully, runs fine on simulation. Please help Share this post Link to post Share on other sites
Posted 27 Apr 2022 (edited) I never use/cant understand structured ladder. Btw, try click Error Help, PLC will tell you whats wrong. Btw, I think, with minor error, your PLC should still be run as usual. Edited 27 Apr 2022 by d4rkm4n Share this post Link to post Share on other sites
Posted 27 Apr 2022 Just guessing, but does your ladder need another rung with an "END" or "RET" statement. Simulation might assume what hardware does not. Share this post Link to post Share on other sites
