7i77 lost connection while encoder counts (PREEMPT-RT)

Category: Driver Boards

pin hm2_5i25.0.write.time did not change anymore.

Suggests this is a PCIE communication issue and probably
not related to 7I77 5V

It may indicate a grounding/EMI issue. Do you have an issue when
the 7I77 in not connected to the rest of the machine?

This is why i asked for a dmesg log as PCIE issues should show up there.

digital outputs remain active after e-stop

Category: HAL

Hello everyone,

I've recently noticed that my digital outputs remain active after an emergency stop. For example, the air used for cooling mist or tool cleaning doesn't turn off. Is this normal behavior, meaning I need to handle it in the program myself, or am I missing something? Below is my current e-stop configuration:

#########################################
# E-Stop logic
#########################################
setp opmode-x-near.in1 8
net  x-opmode-display opmode-x-float.in
net opmode-x-float-signal opmode-x-float.out opmode-x-near.in2

net estop-mpg-ext       mpg-estop-not.out => estop-logic.in-05
net estop-ext     <=  estop-logic.and
net estop-out     <=  iocontrol.0.user-enable-out
net estop-ext     =>  iocontrol.0.emc-enable-in

Any help would be greatly appreciated!
