Hello I have a siemens s7 200 modal number is 216.
I need to cycle between three machines based on run time.
I'm tring to read the real time clock and add seven days to it.
I'm open to any ideas.
Basicaly I have three inputs that will tell me these machines are inabled and three that tell me they are running. When they are running I would like to count the day's/ hours and cycle my machines bassed off of that.
 
Hi there
There is a "READ_RTC" block. You can use it for your purpose.
If input "T" of this block is VB200
then years value comes at VB 220, month value at VB221......

Press F1 after placing cursor on this block, it will come up with all the explanation.
