.SH NAME
|
|
iocontrol \- accepts NML I/O commands, interacts with HAL in userspace
|
|
|
|
.SH SYNOPSIS
|
|
\fBloadusr io [\-ini \fIinifile\fB]
|
|
|
|
|
|
.SH DESCRIPTION
|
|
These pins are created by the userspace IO controller, usually found in $LINUXCNC_HOME/bin/io
|
|
.P
|
|
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 \fBmotion\fR(9) instead.
|
|
.P
|
|
The inifile is searched for in the directory from which halcmd was run, unless an absolute path is specified.
|
|
|
|
.SH PINS
|
|
|
|
.TP
|
|
\fBiocontrol.0.coolant\-flood
|
|
(Bit, Out) TRUE when flood coolant is requested
|
|
|
|
.TP
|
|
\fBiocontrol.0.coolant\-mist
|
|
(Bit, Out) TRUE when mist coolant is requested
|
|
|
|
.TP
|
|
\fBiocontrol.0.emc\-enable\-in
|
|
(Bit, In) Should be driven FALSE when an external estop condition exists.
|
|
|
|
.TP
|
|
\fBiocontrol.0.lube
|
|
(Bit, Out) TRUE when lube is requested. This pin gets driven True when
|
|
the controller comes out of E-stop, and when the "Lube On" command gets
|
|
sent to the controller. It gets driven False when the controller goes
|
|
into E-stop, and when the "Lube Off" command gets sent to the controller.
|
|
|
|
.TP
|
|
\fBiocontrol.0.lube_level
|
|
(Bit, In) Should be driven FALSE when lubrication tank is empty.
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-change
|
|
(Bit, Out) TRUE when a tool change is requested
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-changed
|
|
(Bit, In) Should be driven TRUE when a tool change is completed.
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-number
|
|
(s32, Out) Current tool number
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-prep\-number
|
|
(s32, Out) The number of the next tool, from the RS274NGC T-word
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-prep\-pocket
|
|
(s32, Out) This is the pocket number (location in the tool storage
|
|
mechanism) of the tool requested by the most recent T-word.
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-prepare
|
|
(Bit, Out) TRUE when a T\fIn\fR tool prepare is requested
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-prepared
|
|
(Bit, In) Should be driven TRUE when a tool prepare is completed.
|
|
|
|
.TP
|
|
\fBiocontrol.0.user\-enable\-out
|
|
(Bit, Out) FALSE when an internal estop condition exists
|
|
|
|
.TP
|
|
\fBiocontrol.0.user\-request\-enable
|
|
(Bit, Out) TRUE when the user has requested that estop be cleared
|
|
|
|
.SH PARAMETERS
|
|
|
|
.TP
|
|
\fBiocontrol.0.tool\-prep\-index
|
|
(s32, RO) IO's internal array index of the prepped tool requested
|
|
by the most recent T-word. 0 if no tool is prepped. On Random
|
|
toolchanger machines this is tool's pocket number (ie, the same as the
|
|
tool\-prep\-pocket pin), on Non-random toolchanger machines this is
|
|
a small integer corresponding to the tool's location in the internal
|
|
representation of the tool table. This parameter returns to 0 after a
|
|
successful tool change (M6).
