Conc.: A control mechanism tells the PLC - with the aid of a timer - whether or not goods have passed within the 8 sec.
If not, machine must stop.
Hello,
First of all I must tell you that I'm a big-time newbie.
Am in the process of learning: Siemens, Simatic/S5 version 7.2
A neighbour of mine is building a machine.
He knew I was making programs with Paradox/Object Pal.
So he asked me whether or not I could help him with above mentioned program.
Well, it's a new challenge, so I said I would try.
Secondly I must say I never had a technical education (or computerprogramming for that matter), so I am a self-taught programmer
To test things my neighbour put together a "machine".
PLC=Simatic S5 100U CPU102.
OK, well here's the problem:
Machine does stop when no goods have passed the installed eye.
All the outputs(relays) are reset.
All the flags are reset (as far as I can tell)
I now push on the Start-button:
- test mode/PC monitor shows zero's changing into one (1), as should be.
- the actual relays do NOT react, stay zero.
Two days now I've been trying to solve this, but nothing helps.
Must be overlooking something, but ran out of ideas.
So I hope you can point me in the right direction.
Thanks in advance.
Johanna.
PS. Shall try to enclose what I've made so far.
If not, machine must stop.
