PROFIBUS configuration
● Address
Unique PROFIBUS address of the gateway in the bus system
Range of values: 0...126
Note:
You configure the address of the gateway communication partner in the tab "Process
access > Station configuration".
●
Automatic configuration
– Option enabled
The gateway reads all relevant configuration data from the connected PROFIBUS
network. The following parameters are hidden for the configuration.
– Option disabled
You configure the PROFIBUS parameters yourself.
●
Transmission speed
Transmission speed on the bus, value range - depending on the profile:
9.6 kbps, 19.2 kbps, 45.45 kbps, 93.75 kbps, 187.5 kbps, 500 kbps, 1.5 Mbps, 3 Mbps,
6 Mbps, 12 Mbps
With the "Universal" profile, max. 1.5 Mbps
●
Highest address
Highest possible PROFIBUS address of a node in the PROFIBUS bus system
Range of values: 1...126
●
Profile
Here you can specify the method (algorithm) with which the bus parameters important for
PROFIBUS operation should be calculated. The various methods are optimally adapted
to the respective operating mode of the subnet and result in stable network operation.
– Standard/DP
The DP profile is suitable for using the DP protocol. For an homogenous DP network
with maximum one Class 1 DP master and no other DP masters (additional PG is
possible).
The standard profile is suitable for multi-protocol and multi-master operation with fast
bus nodes, for example, all SIMATIC NET S7 PROFIBUS CPs.
– Universal
For operation with stations that cannot be operated in the DP or Standard categories.
This option can only be selected with a transmission speed ≤ 1.5 Mbps.
– User-defined
With this setting, you can configure some bus parameters.
This profile should only be selected by trained specialists. You should only change the
default values if you are familiar with the configuration of the bus profile for
PROFIBUS.
