PROFIBUS Commissioning
3. Add the built-in slave (BIS) of the HD2-GTR-4PA to the PROFIBUS DP bus configuration.
4. Assign the BIS address set on the motherboard DIP switch to the HD2-GTR-4PA on the
DP bus.
5. Adjust the watchdog. Rough value: 5 seconds (see chapter 6.3.4).
Additional Steps for Redundant Coupling
Note!
PROFIBUS PA Slaves
PROFIBUS PA slaves do not take part in cyclic data exchange The built-in slave (BIS) of the
first DP/PA gateway must take part in cyclic data exchange. If it does not the connected,
PA slaves will also not enter into cyclic data exchange.
Add the BIS of the gateway to the PROFIBUS DP bus configuration!
To enable redundant coupling, proceed as follows:
1. Add the built-in slave (BIS) of the second DP/PA gateway to the PROFIBUS DP bus config-
uration.
2. Assign the BIS address set on the DP bus (the address of the first BIS + 64) to the second
DP/PA gateway on the DP bus.
Additional Steps for Using Fiberoptical Communication
If coupling is designed redundantly and the DP bus uses optical fiber as a communication
medium, additionally perform the following steps:
Adjust the retry limit according to the baud rate (see chapter 6.3.5).

Information on GSD File Conversion
Because coupling is transparent, the PROFIBUS DP master treats PROFIBUS PA slaves like
PROFIBUS DP slaves. This also applies to start–up and configuration.
The GSD file must be integrated in a configuration tool before it can be used to configure and
operate a PROFIBUS PA slave.
Before converting GSD files, always consider the following distinctions between GSD files for
PROFIBUS PA slaves:
Is the GSD file a profile GSD file or a manufacturer–specific GSD file?
■
Is the GSD file designed to communicate via an RS–485 interface (DP GSD file) or an
■
interface according to IEC 61158–2 (PA GSD file)?
If a profile GSD file is being used, the file name indicates whether it is a DP GSD file or a
PA GSD file.
Example 1
"PA039733.gsd" is a profile GSD file for 4 binary outputs.
The name resolves as follows:
PA = PROFIBUS PA slave
0 = DP GSD file
39733.gsd = name of the file
Example 2
"PA139733.gsd" is a profile GSD file for 4 binary outputs.
The name resolves as follows:
PA = PROFIBUS PA slave
1 = PA GSD file
39733.gsd = name of the file
