my recommendation is to get it working in axis and then convert to gmocappy cos it does some funny things. If your config breaks on conversion, raise it with  gmocappy.

This is how I did it with a safety relay and an external latch button attached to the relay that
sends a signal to pin lcec.0.3.in-01 when the relay is enabled
this is inverted and sent to  the drives estop input on all drives.
The estop button is attached to the safety relay

In this case no estop-latch is used,

Thank you but i have seemingly stumbled upon an issue with estop i cannot resolve in any way. Even without any further hal functionality, just ini, configuring a basic gmoccapy and a base hal doing nothing but estop logic i can´t reset estop.

sets external-estop TRUE

setp hm2_5i25.0.7i84.0.2.output-02 TRUE
setp hm2_5i25.0.7i84.0.2.output-03 TRUE

Current version i am trying. I can set external estop via halcmd to either states and try to reset estop with F1 GUI estop
I have built pretty elaborate estop logics with debouncing of external estop time delays and everything, but can´t get emc-task 3 (OFF but no estop) to show.
