igor62il, use OB100 to set some user-defined bit, or useOB1_SCAN_1 information. More about OB1_SCAN_1 on thislink. Hope this helps, Regars. |

Hello , I have not worked on OMRON PLCs but I guess you want to find out how S7 CPUs executes after power on. Organization blocks are the interface of user's program to hardware.OB100 (OB101,OB102 with some differences which explained in STEP7 online manual) is available to determine your program reaction to CPU restart.In practice resetting some bits(or set some), making loops in manual,initialize communication and initializing production sequences are implemented.
