7.13 Handling of the parameters of the system bus
As soon as the system bus extension module EM-SYS exists in a frequency inverter,
the actual value parameters for system state and bus state are activated and can be
observed in the actual value menu VAL of the control unit KP500 or with the VPlus
PC program in the menu Actual values \ System bus.
Note: The actual value parameters are on operation level 3 and are thus avail-
able for the user at any time.
All the setting parameters for the configuration of the system bus are not directly
accessible for the user. For defined customer applications, pre-defined XPI files can
be generated by VECTRON for the VPlus PC program, with which the necessary pa-
rameters are visible for the user. The application-relevant variables are then available
in these XPI files.
Note: XPI files can be read in addition to the loaded parameter information of
the frequency inverter into the VPlus PC program.
In the menu of the software under the point "Edit" you find the com-
mand "Read in XPI file".
The method of working via an XPI file has its reasoning in the fact that deep inter-
ventions in the system are possible via the system bus and can lead to serious prob-
lems in the application with an untrained user. Via the XPI files, a user is given a
selection list pre-defined by VECTRON.
Atten-
tion:
The configuration of the necessary parameters for the system bus is
accessible by a XPI file with the help of the VPlus PC program.
The control unit KP500 does not support this functionality.
If the extension module system bus EM-SYS is installed additionally to a
communication module for the field bus connection (CM-232, CM-485 or
CM-PDP) in the frequency inverter, the parameterization can be made
with the interface adapter KP232.
Experienced users have complete access to all the existing sources and possible input
links with the XPI file of the active functions. The selection depends on the selected
configuration and control procedure.
