    E-stop cover?

    Thanks a lot everyone, I've got enough hints to submit something to my client. I thought E-Stops were more strict than that. FYI, My application does not present risks of mutilation, strangulation. Thanks

    E-stop cover?

    I've just got the strangest request by one of my clients: COver the E-stop. While he does not give any specific requirements, he insists that the E-stop should be covered and personnaly, I think it's pretty strange and it defeats the purpose of an e-stop. Do you guys know any article or laws...

    EMERGENCY STOP rules

    Wiring one signal to an input on 2 plcs.

    Turns out the best option for my equipment and for functionality is going with diodes on each inputs. Indeed, as already stated by someone else, The problem was that my diode was originally placed on the common pin of the PLC. Thanks everyone!!

    Wiring one signal to an input on 2 plcs.

    Thanks for all of your inputs... I will conduct some more tests today and decide on a final arrangement!

    Wiring one signal to an input on 2 plcs.

    Thanks everyone! I have tried with a simple resistor in series to the input and it works! I installed a potentiometre and ramped it until the effect I described disapeared. I measure the potentiometre setting and I need a 3.6K resistor. Thanks!

    Wiring one signal to an input on 2 plcs.

    A resistor might help to fall below the actuation voltage of the input and ignoring the current being drained by the other machine... I'm sourcing I think (I'm always confused between the two. My common pin is 24 volt positive (on the PLC card) and the signal I'm giving it is the 0V (negative)...

    Wiring one signal to an input on 2 plcs.

    No, I'm using a level sensing device which has dry contacts and I'm sending a signal from those dry contact to the inputs of 2 machines.

    Wiring one signal to an input on 2 plcs.

    I have a common sytem using dry contacts for level monitoring and the dry contacts send signals to two machines. I have wired the input on the same contact i.e: Input 13 of machine 1 is wired to the same contact as Input 13 of machine 2. When both machines are powered up, everything works fine...
