TILEPorcelain vs. Ceramic Tile: A Five-Scenario Showdown
Explore where and why one of these popular tile choices makes more sense than the other
Full StoryI know this is slightly beyond the scope of this forum but it's not a far stretch to imagine that someone here has experience with these things.
I just acquired an Allen Bradley SLC-150 Processor Unit. I intend to resell the darn thing, but would like to be able to give a potential buyer some idea of its functionality.
I went ahead and wired up an AC cord to "115/230 VAC" and "115V NEUT" and plugged it in. "DC POWER" and "CPU FAULT" light up. The latter flashes/flickers a couple times so something in there is doing something, but I have no idea if it's doing what it should be.
This one does not have the optional battery, and has definitely been unplugged for more than a couple weeks. It definitely has no program in RAM, but it does have an EEPROM. Of course, I have no idea what program is in the EEPROM. My brief google searches have indicated that there has to be a comment added in the program in order to allow it to be autoloaded from the eeprom, and I don't know if that comment is in there.
Will a complete lack of a program cause the "CPU FAULT" LED to be lit? What further do I need to do in order to get this thing to pretend to do something functional? Downloading something and fabricating a cable to attach to a PC is not beyond my ability if that's what it'll take...
