My u90 ladder doesnt contain the FB tab, how can I download it. Any help?

U90 doesn’t use function  blocks.  It uses special registers in order to accomplish the work of a function block.  Refer to the help files.

And further to what Cam has said, if you need to repeat a "function block", you have to do the same register work again for your next requirement.  This can be a little confusing as you might think that this will upset things by having more than one reference to the involved registers in one scan.  But the scan runs through and treats each "FB" separately, as long as you follow the rules.

Well than I need help in coding for a PID controller for a JZ20-R16. I've read alot of sources, and all the sources refer to a function block tab, which my program lacks. If I dont have the tab what are the ways to device a good PID Controller code?

[Ausman]

Sarkis, have you read the Help files on PID that are native to U90? 

PID is listed under the Controller header and opening it lets you do all details.

cheers, Aus

It's also under Tools in the tree.

 

I recommend you look at some of the PID example programs under Help-> Sample U90 Projects.
