Single Acting Solenoid Valve Does Not Actuate

[valerianlin 0]

Hello, attached below I have a simple program that once the input is pressed, the single acting solenoid valve will actuate. The problem is the solenoid does not actuate once I press the pushbutton, and can see that there is powerflow through the button to the solenoid, but it does not turn on. However the solenoid actuates when I force it or set it on. Is there something wrong with the wiring ? Or is it the programming itself? 

For wiring, I have the red wire from the solenoid going to V+, the black going to the PLC output card, and the common of the plc output card to V-. It seems simple enough but I cannot figure it out.

Thanks

Check to see if the same output is used elsewhere in your program. Also check to be sure that the rung is being processed.

Along these same lines, make sure the code is actually in the PLC.  When you press the button, does the center of the coil light up?  I am assuming not....
