Subject: Konnect Board Help

Good Morning,


We are really struggling with the inputs on our Konnect boards and I have a few questions. The common is connected to +24V and we use a selector switch to ground the input. Occasionally the input stops functioning. I looked at the spec sheet for the OPTO input and it is rated for 35V. Is it possible that there is some ringing caused by noise in our mechanical toggle switch? Perhaps very quick voltage spikes are roasting the input? 


Another question - When we have a following error on our closed loop steppers, and entire bank on the Konnect board goes high. When I run a program to clear the following error, the first bank starts functioning normally, but another bank goes high very quickly as the the fault resets. This triggers anything plugged into the inputs that momentarily go high - in this case the cycle start switch. 


Is this a known issues with the Konnect? We are running version 4.33q, maybe it has been fixed with later firmware?


Thanks,


Scott

Hi Scott,

Are you saying Konnect is permanantly damaged?  Or just stops functioning until it is re-initialized.

If KFLOP receives an incorrect signature from Konnect it will stop communicating and show a signature error on the Console.  Are you seeing this?

Regarding Following Error effecting Konnect.  There was a Konnect timing bug fixed that occurred in some cases when Axis 6 was disabled that was fixed in 4.34a after your Version 4.33q.  How is your Axis 6 configured?

Test Release Changes KFLOP/KMotion Versions 4.33 -> 4.34a 03/09/2016
KFLOP - Fix Timing Bug (resulting in Signature error) with Konnect when Axis 6 is disabled and NO_INPUT_MODE or ADC_MODE

Regards
TK

Tom,

I am using channels 0-6 on my machine. The Konnect is not damaged permanently. The way I have things set up is that any following error disables all, including 6. Before the following error, an entire bank of inpputs works fine, after the error the bank locks on until the axis is enabled. When it is enabled a whole other bank of inputs pulses quickly causing any all of the pneumatic valves hooked up to that circuit to pulse on. My temporary fix has been to avoid those two banks of IO. I will try to upgrade to a later version and see if the problem persists.

Thanks,

Scott

Hi Scott,

Well disabling Axis 6 fits the bug scenario but you forgot to tell us how axis 6 was configured.  Anyways please update.
