2.7.10 Configuration of machine control panel, handheld unit
General
The communications system integrated in the NC permits a maximum of 2 machine control
panels and one handheld unit to exchange data with the 810D and the 840D. An SDB 210 is
not required to transfer the signals of these components. The information given below is
based on the assumption that no SDB 210 has been installed for the components
concerned.
The components are parameterized by calling basic-program block FB 1 in OB 100. FB 1
stores its parameters in the associated instance DB (DB 7, symbolic name "gp_par").
Separate parameter sets are provided for each machine control panel and the handheld unit.
The input/output addresses of the user must be defined in these parameter sets. These input
and output addresses are also used in FC 19, FC 24, FC 25, FC 26 and FC 13. Addresses
for status information, MPI or OPI (a GD parameter set must be set for the handheld unit
rather than an MPI address) must also be defined. The default time settings for timeout and
cyclic forced retriggering do not have to be changed.
