PROFIBUS Configuration
The PROFIBUS configuration is shown in the figure below. The Device PROFIBUS
configuration window is opened by either double clicking on the slave device in the
tree or right-clicking the slave device and selecting
Configuration
.

– Field Device PROFIBUS configuration parameters
The PROFIBUS configuration consists of the following parameters:

– Field Device PROFIBUS configuration parameters
Parameter
Description
Node Address
This is the station address configured for the added device. This is the
address the PLX51-PBM will use to look for and configure the device for
Data Exchange.
TSDR
This parameter is the minimum time that a PROFIBUS-DP slave must
wait before it responds. It must respect the rule:
Min: 11
Max: 1023
Default: 11
Minimum Slave Interval
This is the minimal time that the PROFIBUS must wait between two IO
data exchanges with this device. The default value proposed comes from
the GSD File.
Min: 1
Max: 65535
Watchdog Enable
Enables the watchdog for the slave device data exchange. The slave
device monitors the data exchange rate (PROFIBUS Cycle) and it must
be less than the Watchdog Value else the slave device will change back
into an unconfigured state.
Watchdog Value
Is used to monitor cyclic communication and must be significantly higher
than the time required for one PROFIBUS cycle. If a slave does not
receive a request frame for a period of time longer than the watchdog
time, it will revert to its initial, power-up state and cyclic communication
will have to be reestablished.
