Hello out there

I come in peace.

I used alot of hours on exporting PCSchematic I/O lists to all kinda PLC's. And now i decided to start a thread about this. Discussing how to, why and finaly uploading 'Setting' files to do this.

I know that we don't use the same PLC Reference symbols and PLC I/O symbols, but when you get the 'syntax' it's easy to change and adapt.

I start out with Schneider Modicon M340 PLC CPU.
There are something that you need to have in mind when writing your PLC I/O's.

• No symbols are allowed becide 'Underscore' _
• No 'Space' in the text ( don't use space bar :) )
• Keep the texts as short as possible.
• Dont use numeric characters in the beginning of the text.

If you remember these things you shouldn't get any errors when importing the file in Unity.

PCSchematic settings: ( Sorry, it's in danish )

Your export file should look like this when done:

T.Beskr
This is the text you want to get in your PLC I/O

T.Funktion
This is the I/O number. In this case %I0.1.1, %I0.1.2 and so on.....

T.Label
This is tells the PLC what it is. A EBOOL or INT. 
EBOOL for Digital Input / Output
INT for Analog Input / Anlog Output.

Here is the Input symbol as it is:

Last but not least you can download the PLC file as i use it.

Hope you join this thread and share your files with me. This can save us all a lot of working hours.

Best regards.

Hi Martin !

I'll see what i can contribute with. At Grundfos we use Rockwell PLC's.  Our list look's a lot like

your M340. At the moment we don't use the label box.

How do you control the line brake when you write the description with out any space. e.g (Power_supply_.....)?

I can't get PCS to make the line brake correct if there are no space in a sentence?

Hi JohnL

Ahh i didn't see that coming, the 'wrap text' function (or what you might call it in English) doesn't seem to work as i thought.

I didn't notice it in my 'tutorial' and haven't used in practice yet.

I cann PCSchematic and find out how to get 'round this little problem.

Best regards
