Yes. As long as you keep things from getting split brained.

What do you mean split brained?
Garyhlucas,
I have used both the Click and the BRX. Here are my thoughts, for what its worth.
The BRX is extremely powerful and the cost can't be beat for what you get. So many features and easy to use software.
The Click is an unbeatable cost for function, IMHO, and is powerful enough to use.
I like the Click matched with Mach4 because it is easy to interface the TCP Modbus. And the most difficult thing I control is the Tool Change with the PLC and that's easy to program.
Also, since I don't connect machines to any outside network, I don't have to set up each modbus contact. I just start my Modbus range with the Modbus address on the click and I don't have to configure anything else.
I use the Click because it does what I need and doesn't have the extra bells and whistles sitting there looking pretty because I don't use them.
But again, the BRX is an awesome little PLC!
