s7-300

Currently I am working on s7-300 I need help to devolp 3element drum level controller, Can anyone helpme

In the TI - S7 subdirectory in the Standard Library you'll find the FB85 DRUM block. Have a look at the Help file (click on the Block and then press F1) and see if it does what you need.

Sorry Ron;

If you have a look at this site, yoy will see that a TI505 DRUM instruction will not exactly fit the problem:

This would be more on the level of Peter Nachtwey, Ron Beaufort and our friends at Controlguru.com, no offense to anyone here.


Hope this helps,
