  • Getting started with discrete input

    Hi guys,

    I am very new to PLC programming using Click PLC. I rencently purchased a Click PLC C0-12DD2E-2-D.

    I made a very small to program to test a sensor (on X001). As far as i go, the PLC cant seem to read the input.

    I then directly put on X004 the 24VDC and verified it using my multimeter. The voltage is 23.97 VDC.

    I cant see to find what I am doing wrong. Could it be a configuration parameter?
    Can anyone help me finding the problem?

    I will add picture of my "program" and my configuration.
    I updated the firmware and selected the proper PLC.

    Thanks!

    " then directly put on X004 the 24VDC and verified it using my multimeter. The voltage is 23.97 VDC."

    Do you have C1 connected to 0V?

      I did not. Should I have 0V on C1?
      thanks

        Please study carefully study the diagrams in the manual. If you don't understand the diagrams let us know.

          Wire C1 and C2 to your 24V common. Happens all the time
