SIMOVERT MASTERDRIVES
The CBP can be operated in two ways with a SIMATIC S7:
♦ As a standard DP slave
♦ As a standard DP slave with extended functionality for SIMATIC S7
The CPUs with integrated PROFIBUS interface such as CPU315-2DP,
CPU413-2DP, CPU414-2DP or CPU416-2DP etc. can be used as the
possible S7 master.
The master station as well as the whole PROFIBUS network is
configured in the STEP 7 hardware manager.
Requirement: STEP 7 from V3.0 upwards
If your STEP 7 hardware catalog does not yet contain the entry
"MASTERDRIVES CBP", proceed as follows:
Copy the type-description file S18045AX.200 from the supplied CD into
the STEP 7 index STEP7 à S7DATA à GSD.
From STEP 7 version V4.01, the CBP is contained as standard in the
hardware catalog, i.e. from version V4.01 onwards, the CD is of no
significance.
In the "Extras" menu of the SIMATIC hardware configuration, then select
the menu item "Update GSD files" and carry out this command.
You will find the CBP in the "Hardware catalog" menu under
"PROFIBUS-DP à Further field devices à Simovert". It appears there
under the name "MASTERDRIVES CBP".
To enable the CBP to be connected as a standard DP slave with
extended functionality for SIMATIC S7 (e. g. acyclical communication
with DriveMonitor) to the PROFIBUS-DP, a so-called DVA_S7 object
manager has to be installed as an add-on to STEP 7.
The DVA_S7 object manager is part of the DVA_S7 module package.
STEP7 basis software, Version V3.1 and upwards, is a requirement for
installation of the DVA_S7-OM.
The DVA_S7-OM takes on the function of a master file or type-
description file and supplements the unit characteristics stored there with
all the necessary S7 characteristics.
If the CBP is configured in SIMATIC S7 using the DVA_S7 object
manager, a diagnosis alarm is automatically generated for the converter
fault in the S7-CPU. This diagnosis alarm is derived from bit 3 of the
status word (collective fault) and results in a STOP of the S7-CPU if the
OB82 (diagnostics organization block) is not programmed.
For the correct processing of the diagnosis alarm, the status word of the
converter always has to be transferred unchanged as the first word from
the converter to the CBP (see section "Process data interconnection").
When a converter fault occurs, the CBP2 does not generally trigger a
diagnosis alarm.
