Output Pins
« on: February 11, 2012, 12:58:15 PM »
Hello World,
Simple question, I'm 1 Output pin short using the pins 1 - 9, 14, 16, and 17 for a project I'm creating.  What happens if you attempt to use an Input pin as an Output?  Is there another way around this, I'm already using a 2nd BOB?
Thanks, John

I think if you need more than what one port can provide, you're better off with a PLC.  PLC's are cheap now-a-days.  You can buy a CLICK PLC for what a good PCI parallel port card costs.

Also you could use a PoKeys.

Thanks guys,
I started out with Click PLC's to get the job done, but in the long run, many modules, and NOT near as easy to program, and much less functionality than an Arduino provides for a tenth of the money!
I'll check out Pokeys.
Thanks for the response, John

I find the DL series PLC's easier, but they cost a little more.  Arduino doesn't have Modbus built in to communicate with Mach.  As Hood suggested, Pokeys would be more economical ass it's just a USB device. Depends on how "industrial" you want to go.

Personally the DL06 is hard to beat, expensive if you need to expand but as rrc says its industrial quality. I use one on each of my machines (except Coilwinder) and they are very easy to programme and very configurable.
I will be using the PoKeys on a wee lathe I am doing, it will be the Ethernet version of the PoKeys and I will be interfacing the I/O via a breakout board that has differential 5v  and 24v I/O which should make it more suited to industrial environments.
