I've configured a CPU 1214C DC/DC/DC(6ES7 214-1AG40-0XB0,v4.4), but I'm encountering an issue when trying to download the program. The error message "error downloading to device" appears consistently. Interestingly, I can download programs to S7 1500 series CPUs without any problems using PLC SIM Advanced V7.0. However, this issue only occurs with S7 1200 series CPUs. Software Installed: SIMATIC STEP 7 Prof-Step 7 safety-WinCC Adv+Unified_Prof - V20.0 Upd1 S7-PLC SIM- V20.0 S7-PLCSIM Advanced - V7.0 Please let me know how to fix this issue or any troubleshooting steps I can follow to successfully download the program to the CPU 1214C DC/DC/DC using PLC SIM in TIA Portal V20? Thank you for your assistance!
