T1000MD888+ (input problem)

[billbryan]

hi there,

I'm newbie in PLC, I have T100MD888+ that I want to connect to a 12V cooling Fan. My concept is just to turned ON/Off the cooling fan via internet for DEMO purposes. My problem is when I run a very simple ladder to switch-on the FAN, is not working. then If I triggered the INPUT1 manually using a ground line then connect to power supply ground, then the light in the LED1 will activate then the cooling FAN will run.

Any idea is appreciated.

Thanks.


Bill
