Does anyone have experience with these, and what are your opinions? We are thinking of using one, and the price is definitely right, but

I have used them before and they seem pretty robust, and certainly are good value for money. One thing that does let the side down slightly is the software, which is nowhere near as good as Allen-Bradley offerings, however once you get used to it is fairly easy to use.

Good day,

I have worked with the 05 extensively and am using it in many applications, from power monitoring of electrical DBs to process control for furnaces.

I have used the 05,105,and 205 series of Koyo PLCs and have been pleased with them. The 05 for the money can't be beat. And now with the intro of a analog I/O card for the 05 it has every thing offered in a AB Micro at half the price. I must agree that the software is a bit lame, but you can't have it all.
