I'm configuring a P1-540 and a C-More EA3 for a CIP skid in a brewery. I am trying to add a bit of safety to the machine, so the pump only runs when certain conditions are met. It's pumping 180 degree caustic soda with a 15hp 460v pump, so safety is imperative. Pump switch off = pump indicator off, pump off Pump Switch on, conditions not met = pump indicator flashing, pump off Pump switch on, conditions met = pump indicator steady, pump on. What I can't figure out, is an effective OR or ELSE statement. Like, actual logic items. I'm having a hell of a time achieving this. Can someone help? { "data-align ": "none ", "data-size ": "large ", "data-attachmentid ":126148}

Pump switch off = pump indicator off, pump off
Pump Switch on, conditions not met = pump indicator flashing, pump off
Pump switch on, conditions met = pump indicator steady, pump on.

Your issue is you have "Pump Status " as an output, twice. In PLC logic, last instance of this output wins.
Change your "Pump Status " flasher output to a new tag titled, "Pump Status Flasher. "
Next, create a third rung, with an OR of two NO contacts. One NO contact will be "Pump, " the second NO contact will be, "Pump Status Flasher, " and your output will be, "Pump Status. "
This should get you what you 're expecting; a flashing light when conditions are not met, and a steady when conditions are right.

That worked, thank you!
Side note, I 've been using the Do-More Simulator. Does Productivity Suite have a simulator - it's getting frustrating testing at home in a separate program.

Unfortunately, no. The only other option is purchasing the starter kit. It's what I use to train my colleagues. $298.00 is not bad. Link HERE.
Edit: On your rung 1, eliminate the output "pump status " ORed with "pump " and in rung 2 change the NO "pump status " to "pump. "

I want to believe that if we all scream loud enough, it's something they'll consider adding.
For now, I have a P1K / 08SIM / 15CDD1, powered from a USB port on my laptop that I use for simulating. Of course, you can't simulate the entire program usually, you have to break it down in to sections, but it get's me by, albeit in a frustrating way.

One *almost* excellent thing that the P-series has is Debug Mode.
if debug mode did not require a STOP-Mode, I would use it more.

I'd love to have a simulator as well, but with the P1K, and some creative aliasing, I can simulate all the I/O with a Data View window...

I remember going out to dinner with some of the Productivity team ~4 years ago, asking about a simulator and them looking at me like I had a 3rd eye. "Why would you want a simulator? "
Right now I'm sitting at my hotel in Indianapolis and I would really like to test a theory on some code that is floating around in my head. That's why.

Gotcha.
I live in Indy. Want to borrow my P1K? I'm on a different project for a few days :) PM Me...

I appreciate the offer, but all is well. I have a few dozen P1K and P2K back at my clients facility that I'm working at this week. I have a USB powered P1K that I usually have with me, but I left it at their facility last night.
