Subject: Problem with KSTEP Opto Inputs?
I am trying to install homing sensors on a system that uses a KSTEP.

I have three switches wired to the opto inputs 0,1,2 as illustrated in the manual (JP33 Pins 9,10,11 switched to ground of power supply, positive terminal of power supply to JP33 pin 8).

Based on the digital I/O screen, the switches are turning on/off KFLOP I/0 #4,5,6 and NOT kstep #'s 168,169,170 as I am expecting.

Just to be clear, this is the behavior:

When the switches are open:
I/0 #4,5,6 are showing ON.
I/0 #168,169,170 are OFF.

When the switches are closed:
I/0 #4,5,6 are showing OFF.
I/0 #168,169,170 are OFF.

Hi Jim,

It sounds like the KFLOP hasn't been enabled to multiplex in the 16 KSTEP Inputs.  The 16 KSTEP Inputs are multiplexed in 4 bits at a time by the KFLOP firmware when:

KStepPresent=TRUE;

Have you added this command to your Initialization C Program?

Thanks Tom, I missed that.
