S7-200 Q not working

Good morning, i bought a used 226 216-2ad22-0xb0.
The Q1.2 -> Q1.7 are not working.

i made a very simple KOP for testing.
When i use Q0.0 -> Q1.1 they works (led is on, current flows), but when i try to use Q1.2 -> Q1.7, status leds are off and current don't flow.

i use microwin 4 sp9 (latest version).
the plc is correcty viewed by microwin: 226 ver 01.23.
Q commons are feeded.
on "information on cpu" in microwin there are no problem.
it's strange that the status leds are off.
are the Q broken, or it's something else?

another problem. the serial port 1 is not working.
I try to connect it to pc or td200. td200 tells "can't connect to plc" but it is feeded. the pc don't communicate. the port0 is working.
it's some configuration problem? i

I remember years ago a problem with an S7-200 port not working. It transpired that it had got itself some form of never-ending loop and I needed to run a .bat file or something like that to 'force' it open again.

The details are hazy but I *might* have the .bat file on my home PC somewhere? Have a look into it and, if it sounds like this is your problem, and you need the file I'll look later when I get home for you.

As for the outputs not working. I'm assuming there's nothing in the existing software holding them off?

I don't know a lot about S7-200 but have you tried doing a full memory reset on it?

no, it's simply a |I0.0| -> |NOT| -> (Q1.X)
Q0.*, Q1.0 and Q1.1 work, Q1.2/7 no.

Memory reset? never hear about it...
do you remember how can i do?

Are your inputs i1.6-i2.7 working?

If not, it may be a "repaired" plc with processor part from s7-226, but with the i/o and port part of a smaller unit like s7-224.

The memory reset was a bit of a shot in the dark. I can't remember doing one myself but I'm just guessing that there would be a way to do it as most other PLCs have a 'reset' mechanism that you can access without getting online.

I'll look for that file tonight for you and get back to you.

Maby this can be usefull

Aha!!! Good find!!!

That's the program I was talking about it.

I've used it before when I couldn't get online and it worked a treat (hence why I saved it to my home computer in case I needed it again).

Well found dal!

nada de nada.
it doesn't work.

diocancaro.

That's a shame. I'm not sure what to suggest then, sorry :-(

We'll have to wait for someone more knowledgable on S7-200 to come along :-(

did you test the inputs I asked?

the inputs work.

Try unplugging all the wires. Take a good look at it and smack it around for a bit. See if that helps....and Yes i'm serious, >_>
