Level of protection
–
Here 1 of 3 protection levels may be set to protect the CPU from unauthorized
access.
–
Protection level 1 (default setting):
No password adjustable, no restrictions
–
Protection level 2 with password:
Authorized users: read and write access
Unauthorized user: read access only
–
Protection level 3:
Authorized users: read and write access
Unauthorized user: no read and write access
The properties dialog of the MPI interface is opened via a double click to the sub module
MPI/DP.
n
Short description: Here the short description "MPI/DP" for the MPI interface is speci-
fied.
n
Order no.: Nothing is shown here.
Name: At Name "MPI/DP" for the MPI interface is shown. If you change the name, the
n
new name appears in the Siemens SIMATIC Manager.
n
Type: Please regard only the type "MPI" is supported by the VIPA CPU.
n
Interface: Here the MPI address is shown.
n
Properties: With this button the properties of the MPI interface may be preset.
Comment: You can enter the purpose of the MPI interface.
n
n
Diagnostics: A diagnostics address for the MPI interface is to be preset here. In the
case of an error the CPU is informed via this address.
n
Operating mode, Configuration, Clock: These parameters are not supported.
Except of the VIPA specific CPU parameters the CPU parameterization takes place in the
parameter dialog of the CPU from Siemens. With installing of the SPEEDBUS.GSD the
VIPA specific parameters may be set during hardware configuration. Here the following
parameters may be accessed:
n
Function RS485 (PtP, Synchronization between DP master and CPU)
n
Token Watch
n
Number remanence flag, timer, counter
Priority OB 28, OB 29
n
Call OB 80 on cyclic interrupt error
n
Since the VIPA specific CPU parameters may be set, the installation of the
SPEEDBUS.GSD from VIPA in the hardware catalog is necessary. The CPU may be con-
figured in a PROFIBUS master system and the appropriate parameters may be set after
installation.
