The search for documentation... subroutines in GX Developer?

Hello all,

I've been trying for a little while now to find documentation that will let me know how exactly I can set up the PLC equivalent of subroutines (or procedures or functions), so that in the future I won't have to do what I spent the last day and a half doing, namely making identical changes to the control logic for multiple pumps. I'd much rather make the changes only once - so much less error prone. And so much less boring...

I'm using a Mitsubishi QnA PLC, and programming with Melsoft GX Developer 7.

I must not be using the right search terms, because so far I've come up dry. I've heard such a thing is possible, and I'd really like to be able to use it.

I would greatly appreciate any pointers to documentation that will get me started.

Thanks in advance,
Rhonda

I am not quite sure I know what you mean but in GXdev you can use macros.
Under project/macro.

You can write a section of code then save it as a macro with an identifying name.

These macros can then be inserted in any program.

It could be just what you need

If you have the money, go for GX IEC Developer, this has all you need to create functions & save them/import them into libraries etc.

Right on, I'll look into that. From a first glance at the manual it looks like it's going in the right direction, at least!

Thanks,
