Put the PNP sensor on input 4 in the second group and took that group's COM to 0V. First group's COM back to +24V for the three NPN ones. Everything r...
Shop owner got an electrician in this week. 440R dual channel relay, both NC blocks on the mushroom, contactor coil through the relay outputs, mirror ...
Moved that COM to 0V and input 0 comes on with metal in front of it. But now inputs 1 to 3 with the old NPN sensors on them do nothing at all, no luck...
So the rung stays on DI05, but it's not the E-stop, the relay is. And the comm loss setting on the drive doesn't matter for this because the relay dro...
The COM terminal for inputs 0 to 3 is on +24V. That's how it came from the guy I bought it off, not sure it was ever deliberate.
So a 2-wire transmitter needs a power supply in the loop and a 4-wire one has its own? I guess that's the difference?
What's the difference between .PRE and .ACC on the TON? Is .ACC the one counting up?
Put it in as a LIM 1 Idx 20 with a SUB 1 into Idx_0 and the MOV reads Recipe[Idx_0] now. Asked the operators, and yes, recipe 20 is the night shift sa...
The screen has a numeric entry for recipe number, 1 to 20, and it writes straight into Idx. So if they pick recipe 20 it reads Recipe[20]. I think tha...
Change Controller to Emulate 5000 v33 and then I inhibited the EN2T and the two remote racks went with it and download went through, emulator in slot ...
only the PLC. There's one contactor in front of the drive but it's pulled in by a Micro820 output when the machine is switched on. No yellow relay any...
It says 1756-L83E. That's what it is though. Does the emulator want it to say something else?
I'm learning on a Micro820 and did nearly the same thing last month. Is it the divide throwing the decimal away? Mine only ever showed whole numbers.
