PROFIsafe application notes
The maximum number of Inline terminals that can be snapped onto the bus coupler
depends on the following parameters:
–
Maximum number of Inline bus devices that can be snapped on: 62
–
Maximum length of the process data channel: 244 bytes
–
Maximum length of the parameter channel: 237 bytes
Make sure that no parameters are overwritten.
–
When operating safety terminals on the bus coupler, it is recommended that status PDU
diagnostics are activated. In this operating mode, the device and parameter errors are
forwarded transparently by the safety terminals to the corresponding control system.
The bus coupler supports Inline PROFIsafe modules. These PROFIsafe modules can be
operated together with safe and non-safe I/O devices. At present, the following PROFIsafe
modules are available:
–
IB IL 24 PSDI 8-PAC
–
IB IL 24 PSDO 8-PAC
–
IB IL 24 PSDOR 4-PAC
–
IB IL 24 PSDO 4/4-PAC
The modules map 4 words of process data to the local bus and obtain the F-Parameters and
iParameters from the parameter telegram via a 63-byte parameter block. The settings are
provided in the GSD file.
The GSD file (electronic device data sheet) is required to configure PROFIBUS devices.
This file contains all the safety modules that are currently available.
Make sure you always use the latest GSD file. It can be found on the Internet at
In the unlikely event that the GSD file does not yet contain the configuration data for a new
safety module, this can be adjusted manually.
If you have any queries regarding adjusting the GSD file, please contact the Technical
Support Center.
Connected PROFIsafe modules need 30 seconds before they can communicate and be
parameterized.
