relays Configuring the Relay output on V700-T20BJ-N to activate a solenoid

[safchow]

Hello,

I am a first time user for the program and so far i've been learning from using the tutorials and i'm struggling to configure a relay output connected to a solenoid.

So from what i've found i believe i have assigned the solenoid to O0 and have added this to my ladder. Can anyone confirm if this is correct?

essentially i need the solenoid to open when a button is pressed for 2 seconds. Thanks in advance

This is ambiguous. Do you want the output to turn on for 2 seconds after the button is pressed (this is what you have), or do you want the output to turn on after the button has been held down for 2 seconds?

Also, you appear to have the Power-Up for O0 as SET. This will turn on the output as soon as the PLC boots up. Is this what you intended?

I would like the output to be on for 2 seconds.

and no I need the output to only be active when the button has been pressed

Then what you have will work except that the output will already be on due to the Power-Up setting. Change that setting to either RESET or NONE.

Thanks for the help!

You're welcome. I do have to make a correction. Due to the fact that your ladder has a direct coil for O0, the Power-Up setting will have no effect. Turn it off anyway.
