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
of the NC program's unit of measure.
The following is a complete list of the
