Teach pendant waiting for cyclic connection after enabling Fast measurement Inputs

you have a software issue yet you did not state software versions.
then you failed to provide details about file location and exact steps you used to make those changes (and you proceeded like you did).

i searched my computer for such file name and found nothing...

enabling fast measure channels is done through WorkVisual. modifying files without great care can have unpredictable results.

At the top of this file:

Why did you edit a file clearly marked DO NOT EDIT? For that matter, who told you that modifying this file was the way to activate the Fast Measurement inputs?

As Panic said, activating the FM inputs is done through WorkVisual, which will make all the correct XML changes for you.

Since the SmartPad will not connect, you best bet now is to connect a monitor directly to the KRC4, along with a mouse and keyboard. You should be able to restore your previous WorkVisual project, or your last good Archive (I assume you've been making regular backups?).

this was clearly a mistake - not only it tells not to modify it but fast measure interface is part of specialized IO and clearly has nothing to do with axis files.

my guess is that:

a) KRC fails to boot due to erroneous XML configuration. restoring file to original state may/should fix this.
b) reloading image to controller did not work, probably for similar reasons (no or wrong image on usb recovery stick, wrong version of usb recovery stick, wrong configuration of usb recovery stick etc.). this is why i asked for details on exact steps taken.
c) connecting external monitor may not be an option for older system (KSS8.2) as motherboards of that era did not have graphic cards.

b) reloading image to controller did not work

Whups. Missed that part.

i just launched WoV, activated one of projects, compiled it and checked the file. those lines were not present.

then i enabled Fast Measure interface, compiled again and those lines were added.

so it turns out this is clearly proving that such modification is correct though it is hard to tell if that is the only file that got changed.

one can of course ignore warnings and try to make changes manually on the KRC like it was done in this case. but... one has to be very careful. among other things XML files are case sensitive. also if such change is to be performed one should make sure to have valid backup. and after change is done manually, controller need to be restated but this need to be Cold Start with Reload Files.

for something that is easily done in WoV using expected steps, taking risks and making manual changes is clearly not the best choice. i would certainly not advise it to people that may be inexperienced in such things and recovery process.

another concern is that software versions and exact steps are still not revealed.
