I got the process data working. Now I call the FB blocks from FC1.

Changes to FB block:

- I moved DPWR_DAT call to end of the FB block.

- I also moved my TEMP variables to STATIC variables.

But now my timer does not work.  Is there some manual that tells how timers can be used in FB block?

Or does someone know what I'am doing wrong with the timer?

 hello friend,

prepare a timer inbuilt using clock memory or use the system function block timers.

apart from this don't use timers in temp.

I made following changes to program (See the attached picture). I removed the DB4 and defined the timer differently.

Now program seems to be working. I call the FB block 2 times and both FB's are running fine.

Now I need to make proper program in to FB block and test the program with multiple drives.

Hello, 

the best way to handel with the reusable FB's is to :

1. Dont ever use a bit memory Tags  (M) or other predefined variables from outside.

2. use always multiinstances for your Timers, Counters.... etc. 

3. it will be better when you call your FB in your program to call it in an another FB (as examle for a drive in a Mixer part in your program call the FB_Drive in the FB mixer as a multiinstace) it will apear in the static variables area). so you should not give a numbers for the instance data blocks.
