Hello, From your problem description, I have the feeling that an old version of the program is onthe Flash card plugged in the CPU, and that the battery is OK. With the result that after power down, the CPU starts with an outdated program. If you operate your CPU without a backup battery, after startup or when voltage returns following POWER OFF, the CPU automatically undergoes a general reset and then a warm restart or cold restart, depending on the configuration. The user program must be available on the FLASH card. 2. Insert the FLASH card into the CPU. 3. Perform a memory reset. 4. Download the user program with the STEP 7 command "PLC -> Download User Program to Memory Card".

There is a switch OFF/1 BATT/2BATT near batteries - check if it's in correct position. |
