mapping

I have a question before answering your question.

Do you want to use this function in all the programs or you have a limited necessity?

If you want to use it globally then declare a Variable in Config.dat. For Example

REAL REQ_VOLTS ;This variable can be used in any program.

Now, in your routines where you want to call this program SetHz, you can write something like this:

REQ_VOLTS = SetHz (20) ; Value 20 is anonymous, you can take whatever value you want

Therefore, it should give you REQ_VOLTS. Now, you can use this REQ_VOLTS as you want.

This is how Panic suggested doing in earlier posts.

Thanks

Sorry, it was typo on my end.

You should declare the variable in Config.dat as:

DECL REAL REQ_VOLTS

The program looks ok to me.

Now, what are you trying to achieve?

We have already explained in earlier posts that how you can use in your programs.

So after doing the suggested changes, are you getting desired value in variable REQ_VOLTS?

If yes, then you have to transfer the voltage values to ANOUT over Devicenet which can be done in every cycle of SPS.

Also, as I am not aware of your setup which includes the functionality and interlocks. Therefore, depending on various conditions you have to program the voltage reference to the inverter.

To help you more rigorously, I have checked the Expert Programming Manual which included the description of Analog Outputs on Page 112 of the pdf with an example similar to your application.

If you do not have the manual then you can use below link to download:

Have you checked the value of REQ_VOLTS?

Is the calculation done good?
