Hi everyone,

I'm just getting started with Siemens LOGO! and I'm looking forsomeone who could program a small project for me. It's probably simple for someone with experience, but as a beginner, it's still a bit too complex for me.

What needs to be programmed:

1. Pump with flow monitoring

   • Start a pump.

   • Monitor the flow for 10 seconds.

   • If the flow doesn’t exceed a set threshold after 10 seconds, trigger a fault alarm.

2. Alarm light signaling

   • In case of a fault or emergency stop, ablinking red lightshould turn on.

   • During normal operation, asteady green lightshould be on.

So I’m specifically looking forsomeone who can create this program in LOGO! Soft Comfort. And send a picture of it 

If you have experience with Siemens LOGO! and would be willing to help me out, I’d really appreciate it!

Thanks in advance!

Best regards,

Max

someone who could pre-program a small project for me.

What do you mean with pre-program? And what is a small project for you?

1. Pump with flow monitoring

   • Start a pump

What flow? You don't write anything about where flow data come.

1. • Start a pump.

Start a pump? Have you more pumps? In your first topic you ask your changing pumps:

If you have experience with Siemens LOGO! and would be willing to help me out, I’d really appreciate it!

Helping? Yes.

Write a complete program? No.

Then ask for step by step.

Hi mate,

Your description is a little bit strange when you say...

• If the flow doesn’t exceed a set threshold after 10 seconds, trigger a fault alarm.

I supposed that fault alarm should be launch when reach a threshold, right???

If you need the inverse, now it is easy to edit as you want.

Anyway, find attahced my idea with alarm when reach threshold, example with number 150 in (B005).

I used the LOGO 8.4 and flow signal thru Analog input AI1.

Hope it open up your mind!
