Step 7 SCL array shifting

Hello,

I am trying to shift the existing timers in array and insert the new one at the beginning, but can't understand why this doesn't work.

Тhanks in advice!

Hello,

I don't have a taste to deeply check your test and if it is functional from basic principle  but genrally I expect this procedure not possible in maybe basic reason. Your Timers need to be stopped or finished to do some manipulation with them as move times. What I also expect to be functional is to have statically defined value of time inside array element, as test.

Where should the array in FC10 get values from, in the beginning?

The array in FC10 is declared as temporary storage. That means the values are invalid after a PLC cycle. You will see the effects as soon as you have another code block using the temporary storage area. The static tags in an FB is different - the values are stored.

In the program M1.1 needs to be on for only one scan, which does not happen now.

I would expect the timers listed as outputs in FC10 is best put to In-Out parameters, if these should be read by the array.

Indirect addressing techniques my be better suited for the task you are trying to achieve. Then you would directly connect to the storage DB.
