Inputs Not Registering on Jazz JZ20-T40 Debugging Mode

Recommended Posts

I have a Jazz JZ20-T40 that I wrote a program for and am attempting to check the logic.  I download the program and enter debugging mode.  I wrote in SBs for HMI buttons to check the outputs which work fine.  However, when I give the inputs 24 VDC with a wire to check them, they stay at 0 on the inputs screen.  Shouldn't the inputs change to 1 when given 24 VDC?  How should I go about checking my input logic on Jazz PLC?
