The picture (below) of the Home Automation "Gator PLC" which is 3/4 complete. Still waiting on parts for the 3 pin A/D interface board, which connects to the upper left corner of the Gator microcontroller.
In the picture, from the top left, is the BlinkM I2C RGB annunciator and the ChronoDot RTC. Below that, is the 5 VDC and I2C bus board. Then comes the LCD terminal display, the 1 amp 5 VDC power supply, the Gator and Watchdog and 12 VDC Bus Board. Last is the Parallax Digital I/O Board.
This development PLC panel is used for software development and PLC I/O simulation.
The final PLC end product will be installed in a Nema enclosure.
BTW ... everything works fine, so far.
