Can I access Weintek's Codesys function block's within EasyBuilder Pro?

    I’ve downloaded a sample project that uses a PID function block.

Does the function block travel with the project?
If so, in Easy Builder Pro, where do I find the function block to view the settings?
Where do I find the signals to invoke the function block?

Or must the library be loaded? Where is the PID function block visible in my Easy Builder software?

Hi @mike_c_56,

The function blocks are components of Weintek’s Codesys library. Please make sure that you have installed Weintek’s Codesys package which includes our Codesys library:

Codesys is a separate entity that is built-in to the HMI. It must be programmed with the Codesys IDE. Please see this post for more information: Click Here

I have downloaded Weintek_CODESYS_and_RemoteIO_1.4.0.435 and installed.
But I don’t think my Codesys installation is finding the library it needs.
And when I click to load the missing library just get “download failed”.

Brendon, Yes this worked. My oven demo loaded without error.
I’m not sure what I’m looking at though. Is this a PID function block? Can I add ladder logic to invoke this when the machine is ready?
I need to brush up on my Codesys a little and dig into some more documentation or Youtube videos from Weintek.

Thanks for your help on this. Regards, Mike
