NAME

iocontrol − accepts NML I/O commands, interacts with HAL in userspace

SYNOPSIS

loadusr io [-ini inifile]

DESCRIPTION

These pins are created by the userspace IO controller, usually found in $EMC2_HOME/bin/io

The signals are turned on and off in userspace - if you have strict timing requirements or simply need more i/o, consider using the realtime synchronized i/o provided by motion(9) instead.

The inifile is searched for in the directory from which halcmd was run, unless an absolute path is specified.
