FN 18: SYSREAD – Reading system data
With the
FN 18: SYSREAD
function you can read system data and
store them in Q parameters. The selection of the system datum
occurs via a group number (ID no.), a system data number, and, if
necessary, an index.
The read values of the function
FN 18: SYSREAD
are
always output by the control in metric units regardless
of the NC program’s unit of measure.
The following is a complete list of the
FN 18: SYSREAD
function. Please be aware that not all
functions are available depending on the model of your
control.
