I'm taking a class so I wanted a plc to practice on. I bought an SLC 500 10 slot rack on ebay. The guy that sold it to me claims he is sure it works. I have not been able to clear the blinking fault light. I can not get RSLogix to communicate.
I am using rslogix 5 ver3.2.
Using the Serial cable 1747-cp3
I tried the same DH+ cable that I use on a Micrologix 1000, but it won't configure itself.
I hook up the (serial) cable, power up the rack.
After start up the fault light is blinking steady.
The rs232 light is blinking intermitently, but rapidly when it does.
The DH+ light blinks occasionaly, but steady.
I am using the same comm port on the Micrologix1000, so I know it works as com1, and the speed is at its max.
In Rsinx I go into communications and choose autoconfigure.
It reports success!
Now I go to the tree view in links, and it shows the 5/04 station 01, now named default , and lists it as faulted. (I would think it would have to communicate to know its faulted?)
It looks as though it is communicating ok from here.
I go into rslogix configure a new project.
I name the processor TEST.
I use soft controller, (its either that or plc5 in this vesion) it does the rest of the settings, I have no choice except the cpu which points to the one in rslinx.
When I get into the tree view project I dbl click on SLC 500 I/O to get the configuration screen for the rack. I use the A10 rack, select use SLC I/O, and click on "read I/O config"
Now it pops up a box saying "cannot get connected to online processor"
I have tried setting the cpu to factory, using gnd-vdd. (I think thats how it got named DEFAULT.)
Switching from program to run didn't work.
I took out the memory card.
I took out all the I/O cards in case one of them was messed up.
I took out the backplane circuit board and looked it over with a magnifying glass, and found a burnt resistor. After much research I found something from AB that said it should be a 1M resistor, so I replaced it with a new one. The old one was burnt to bad to tell from it what it was.
I do not have a power supply pin out, but I found both 24 volts, and 5 volts on the connector pins.
So far none of these things has made any difference.
Does anyone have any other ideas to fix this thing?
Can anyone confirm that the backplane resistor is supposed to be 1 Meg? It is the one that goes from Logic ground to Chassis ground.
Will this software just not work with this SLC?
Thank You for taking time to read this rather long first post.
