S7-200 SM31.7 problem

Post by ghulamshoaib »

Hello,

S7-200 CPU 224 CN is installed and SM31.7 is used for data write to EEPROM

Now I have uploaded the program from CPU 224CN and downloaded it to CPU 224 standard

problem is that when I set SM31.7 then it does not go back to 0 state and remains ON

what may be the reason?
