Hello engco; It seems like a good time try and look at the diagnostic buffer of your CPU, to see if any message can help you understand what, in your program, makes the CPU unhappy. If you can access the diagnostic buffer and you have an idea wgich portion of your download stopped the CPU, use that knowledge to modify it. Next, good practices would suggest you proceed to reset the CPU to its factory settings, so as to remove all irritants. After resetting, correct and download your program once more. From the S7-1200 system manual: SIMATIC S7 S7-1200 Programmable controller

14.5 Resetting to factory settings
You can reset an S7-1200 to its original factory settings under the following conditions:
● No memory card is inserted in the CPU.
● The CPU has an online connection.
● The CPU is in STOP mode.
Note
If the CPU is in RUN mode and you start the reset operation, you can place it in STOP mode after acknowledging a confirmation prompt.
Procedure
To reset a CPU to its factory settings, follow these steps:
1. Open the Online and Diagnostics view of the CPU.
2. Select "Reset to factory settings" from the "Functions" folder.
3. Select the "Keep IP address" check box if you want to retain the IP address or the "Reset IP address" check box if you want to delete the IP address.
4. Click the "Reset" button.
5. Acknowledge the confirmation prompt with "OK".
Result
The module is switched to STOP mode if necessary, and it is reset to the factory settings:
● The work memory and internal load memory and all operand areas are cleared.
● All parameters are reset to their defaults.
● The diagnostics buffer is cleared.
● The time of day is reset.
● The IP address is retained or deleted based on the setting you made. (The MAC address is fixed and is never changed.) Hope this helps, Daniel Chartier |

Are you checking the "start all" box when downloading? Post the log file if you can. If you can a memory card reset the unit and try again downloading and starting it. If you don't have a memory card, try resetting with MRES and then download the program and start all . |

First you see the online diagonous buffer. And see the cause which can not allow the PLC to go in Run Mode. If you don't diagonous the cause then post that buffer data hear. Can you try to this process => Option->Start CPU.???? |
