8BCOMMUNICATION WITH OTHER SYSTEMS
9 Communication with other systems
9.1 Hardware and software requirements
For the communication with other automation systems, the ET 200M system is used.
In the framework of the communication system ET 200M, various "head" components
(interface modules) are offered, which are connected to the communication bus
(PROFIBUS or PROFINET). Up to 7 SIWAREX U modules can be configured per
PROFIBUS interface module. According to the PROFINET specification, up to 12
modules can be operated at a head station per interface module.
For the configuration, GSD or GSDML files are used for the communication system
ET 200M. These are made available as a download by SIMATIC Support.
The installation of the GSD or GSDML file is described in the manual of the
respective automation system.
With the aid of the GSD or GSDML file, SIWAREX U can be configured in the
respective automation system.
Note:
There are various *.GS? files. The *.GS
D
files are language-independent files, i.e.
there are no user texts. In these files only the compulsory parameters are stored for
compatibility reasons. The *.GS
D
files are only intended for configuration programs
which do not support the extended parameters. The *.GS
?
(where ?
E

F

=Spanish) are language-dependent. They contain
user texts for configuration in the language of the respective country. All the
information required for the configuration of the plug-in components is contained in
the language-dependent *.GS
?
files (this is not the case for the *.GS
D
files).
Since not all important information for the initialization of SIWAREX U is present in
the *.GS
D
files, one must ensure that the
language-dependent *.GS* file is used
as the data base
.
Each SIWAREX U module occupies 16 bytes for data input (reading from the module)
and 16 bytes for data output (writing to the module) in the address area of the control.
The addresses in the following description (table) are given relative to the basic
address of SIWAREX U in the automation system.
9.2 Communication via the I/O area
To process communication, the status byte and the byte for task controlling are used.
Bit 6 in the status byte (input byte 1 for channel 1 and input byte 9 for channel 2)
can be evaluated as a live bit.
By means of the live bit it can be determined whether the component is still "alive".
To do this, bit 6 in the status byte is to be evaluated. If the status of the live bit in
