Dear eden, Please check "SFC1 (READ_CLK)" to read out date and time of CPU and simply compare details(Year,Month,Day,...) with your set values.You can find a sample program here: How can you read out the date and time with SFC1 (READ_CLK) and input them with SFC0 (SET_CLK)?

Dear eden, It is not really clear what you want. If you want to run an actuator in specific time you can use SFC1 and set of comparators or OB1X as "Time-of-Day interrupt".In OB1X you can select for example weekly execution of codes at pre-determined time of day.You can set these parameters in CPU's propertiesin H.W config. If you want to warm restart a S7-300 CPU from user program check the following discussion here: /tf/WW/en/Posts/62263 Hope this helps Best regards, Hamid Hosseini |
