Term doesn't accept '

[wpattyn]

I'm trying to create a PLC analog input card in the PLC database file editor but i have a problem with naming my terminals. 

One of my terminals needs to get the name B', but every time i enter a terminal point with B' in the TERM, it disappears after i close the editor and try to enter the card in my drawings.

Is it not possible to use ' in the TERM?

Due to how AutoCAD Electrical is programmed, special characters like ' " * # will make the program crash depending on the task you're doing.

To be safe, I would only use dash (-) and underscore (_) as special characters.
