Hi kenzo103, I am sorry to say this but the method suggested by me inmy last post is not a good way... I had forgotten how incompatible PCS7 & STEP7 can be! The main problem with this approach is, you cannot connect the output of SFC1 to FC7 or FC8. You can only connect shared addresses, meaning DB's etc.which is very inconvenient. Imade an FB (STL source attached)which converts the time to INT. You can use this and use CMP_INT to solve your problem. The day light savings (DST) and GMT offset can be removed if not required. Alternately you can use the method described in following FAQ: How can you read out the date and time with SFC1 (READ_CLK) and input them with SFC0 (SET_CLK)? Also, you can use Time-of-Day interrupt. But please see the problems associated with this approach in following thread: TOD to start and stop a function ? Regards AttachmentDT_INT.zip (803 Downloads) |
