PROFIBUS Commissioning

Commissioning of Simplex System and Redundant System

The following section describes communication start-up of the
HD2-GTR-4PA:
1. If necessary, convert existing GSD files of PA slaves with the
P+F-GSD converter and then integrate them into the configura-
tion tool
2. Integrate the GSD file of the HD2-GTR-4PA into the configuration
tool
Because the DP/PA-Gateway is already a DP slave, its device GSD does
not need to be converted. The GSD file of the HD2-GTR-4PA is available
for download at www.pepperl-fuchs.com.
Note
3. Add Built-In-Slave (BIS) of the HD2-GTR-4PA to the DP bus con-
figuration
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 "Addi-
tional Information about Watchdog time" on page 33)

Additional steps for Redundant Coupling

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 cy-
clic data exchange. If it does not the connected PA slaves will also not
enter into cyclic data exchange.
Attention
Add the BIS of the Gateway to the DP bus configuration!
The following additional steps are required for redundant coupling:
1. Add the Built-In-Slave (BIS) of the second DP/PA Gateway to
the DP bus configuration
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 use of fiber-optical zones

If Coupling is designed redundantly and the DP bus uses optical fiber
as a communication medium, the following additional steps must be
performed:
Adjust the retry limit according to the baudrate (see chapter "Addi-
tional Information on Adjusting Retry" on page 35).
Subject to reasonable modifications due to technical advances.
