ESTOP connection to Konnect Board

[AmitKumar171]

Hi tom,

I am using KFLOP+KANALOG+KONNECT for my machine.

I am wiring ESTOP connection to #1037 of Konnect board. Estop is not functional in that condition.

If i remove wiring of Konnect to Kflop (JP8 Konnect+JP6 KFlop) and connect ESTOP directly to Kflop board, ESTOP started working.

Can you explain why ESTOP is not working when it is connected to Konnect board I/O Input.????

Waiting for your kind reply.

KFLOP inputs are LVTTL signals (basically 2V for high and 0.4v for low)

Konnect Inputs are opto isolated 4.5 - 24V signals.

How are you wiring and driving the Konnect Inputs?

Does Bit 1037 change on the Digital IO Screen?

Did you change the ESTOP C Program to use the different bit?

Hi tom,

Thanks for the reply.

How are you wiring and driving the Konnect Inputs?

I have given +24V supply to Com of input commons in konnect, and GND 24v connected to Estop NC ,1 wire and second wire to 1037 of konnect.

Does Bit 1037 change on the Digital IO Screen?

Yes bit changes, and its respected LED on konnect also glows.

Did you change the ESTOP C Program to use the different bit?

Yes i changed it to use on Kanalog bit 137 - opto inputs.

Still not working .

When i removed ESTOP program from INIT file, and made it to use separate thread. It started working. (INIT thread1, ESTOP thread2)

But why it does not work when ESTOP c program included in INIT file. ??

Earlier same C program was working when my ESTOP is wired to KFLOP JP6 directly using 3.3v.

But i used KFLOP+KANALOG+KONNECT , then ESTOP program is not working when it is included in INIT file.

Please update me why it is not working.??

Waiting for your kind reply.

Hi Amit,

Yes i changed it to use on Kanalog bit 137 - opto inputs.

Still not working .

Why would you change the code to use Kanalog Bit 137 when you wired the switch to Konnect Bit 1037?

I have wired the switch to KANALOG bit 137, before changing the code.

Still it not working can you give some suggestions on it.

Waiting for your kind reply.

Hi Amit,

Does Bit 137 change on the Digital IO Screen when pushing the button? What is the Polarity?

Post your Init C Program with the changes that doesn't work.

Post the C Program that works when run in a separate Thread.
