Hi, The safety program put your cpu to STOP. The data used to calculate your outputs in the safety program changed between start and end of your safety program (OB123). Please check this siemens guide: https://support.industry.siemens.com/cs/document/22099875/simatic-industrial-software-s7-distributRead more
Hi,
The safety program put your cpu to STOP.
The data used to calculate your outputs in the safety program changed between start and end of your safety program (OB123).
Please check this siemens guide:
In your error log I can see that the issue is with your %Q430.0 output.
Please check the network where your %Q430.0 output is writen. maybe the data (inputs and other data) used to calculate this output are changed in other tasks.
Best regards
See less3 UsersHi Everyone! I use a s7-1500 controller. I use MB_CLIENT function to read data from an other PLC. Everything work fine until I make change in my project and download to the PLC. I have error 80A3 and impossible to acknowledge until I make a stop/Run of the plc. Anyone can help me? Best Regards,
Hi Maesa, If you use instances declared in a FB function. Try to use a global instance of MB_clien like this: use a global DB to declare the "ModbusDataconnectParamClient" structure. This will fix your problem and when you download the project, it will not cause problem for MB_client function. hopeRead more

Hi, use P_TRIG to monitior everything in the left of this instruction. It turns to ON for one scan when the entire set of logic to the left goes from off to on use -|P| to monitor a single tag. it turns on one scan when the tag goes from off to on. Best regards
