So today I relized that the PLC is an AC output and that is why it worked when I hooked up the incandecent light but it's strange because I did have it working on 24VDC output for a long time. Leason learned and I will try to keep on learning more about PLC's. Thank you all for your help it has...
Thanks for all the responses. This weekend I tried my output with a 120VAC incandescent light instead of the 24VDC I have been using and it worked just fine. So it does look like it's a voltage issue so I'm going to try and get a resistor and maybe a mechanical relay to see if it doesn't help my...
I only have a paper manual. The particular machine that this was on has been running for years with the same program. The PLC went bad and when I put in another 1 is when this started. I even went out and bought another 1 only to have the same thing happen. I think I might switch it out for a...
I understand the sinking and sourcing part. When I check the output without anything attached to it it works perfectly but as soon as I add power to it it becomes latched and doesn't shut off with the release of the input button even though it shows on my computer & PLC that it has. Again my...
No the questions aren't stupid at all and don't mind me if I'm not explaining things properly this is all new to me.
Yes it's in run mode
No program faults
Yes the output state - 0
You are correct that the indicator is showing correctly but the output holds steady at 24v when the button is...
I have a direct logic DL105 PLC and have a simple program with a pushbutton and a light. My input is "NO" and the ouput is "out" so when I press the button the light comes on but when I release the button the lights on the PLC go out but the light itself stays on. This program was ruuning fine...
