Normally, only kinematic-specific machine parameters are taken over.
The general system parameters remain unchanged in the real time core
of the rho4. If all entries are unequal zero, a machine parameter backup
is performed.
SR-CAN serial number
During the run-up of the control it is checked whether the valid machine
parameters in the control correspond to those in the SR-CAN module.
For a quicker verification, only the serial number in the SR-CAN module
is compared with the one contained in the control. If both serial numbers
are identical, the control will run up. If the serial numbers are not identi-
cal, the control will run up with the message ’serialnumber invalid’. It is
then possible to generate valid machine parameters and to load them
into the real time core of the rho4 (see also “MP-Download from VO05x”
in this chapter).
The serial number in the SR-CAN module is not initialized at the time of
shipment. The serial number consists of an Ascii string with 64 charac-
ters which is initialized after a machine parameter back-up. In this case
too, the control will run up with the message ’serialnumber invalid’ (see
also “MP-Download from VO05x” in this chapter).
When loading the machine parameters from the control into the SR-CAN
module, the serial number remains in the control so that the comparison
of the serial numbers leads until the exchange of one of the two compo-
nents, to a complete run-up of the control.
The serial numbers form a part of the machine parameter (P314). For
each kinematic a serial number is provided in the machine parameters of
the control, since it is possible to operate up to 16 kinematics with one
control. If several kinematics have been configured on one control, the
handling of the serial numbers for each kinematic takes place according
to the same procedure.
The operating mode of the machine parameter back-up, enabled by the
key combination permission-key+Alt+Mode+0 at the PHG2000, re-
mains unchanged.
