FP-SMC-1 Interface PCB Project

Wiki page for the Making An Interface PCB Series
The file are here for subversion (Eagle PCB only) and here for WordPress (Eagle and Alibre).

Most of the details are in the blog posts. I created the PCB as an example custom automation PCB. The FP-SMC-1 connects 16 Panasonic FP0, FP0-R, or FP Sigma PLC outputs to the first 8 stations (both solenoids) of a SMC manifold base with a 26-pin flat ribbon cable connector, and 16 inputs to terminal blocks for limit sensors. The board provides input, power, and ground for each PLC input to make connecting sensors easy (and because I wanted to try out the Phoenix 3-level terminal blocks).

I haven't finished the series as I originally planned. Partly, I want to explore more PCB design tools. So sometime, after I finish some higher priority series, I might get back to this series.

If you need a SMC ribbon cable interface PCB, you should create a custom PCB that exactly meets your needs (but of course you're welcome to use the FP-SMC-1 as a starting point).

Panasonic pin outs are from the FP0 CPU Manual. Since the number of I/O matches perfectly with this board, I will use a FP0-C32T as an example. I haven't found a convenient SMC link; from what I've seen (I've looked at three different manifold base series) the SMC flat ribbon cables pin-outs are pretty consistent.
