Connection "DeviceNet"
Baud rate
The DeviceNet baud rate is set manually using the "RATE" selector switches or via De-
viceNet.
Setting the baud rate manually
 Set the selector switches to the desired value.
– The change takes effect the next time the system is switched on.
Setting the baud rate via DeviceNet

Switch off the pump/electronic drive unit
 Set the selector switches to "P".
– When switched on, the system uses the last valid baud rate (500 kBit/s upon deliv-
ery).
– The baud rate is programmable via DeviceNet object 3.1.2.
(see p. 16, chap. 6.5)
.
6.3 Configuring the data exchange
Depending on the program used to set up DeviceNet communication, you can carry out
the following steps:
 Import EDS file (see scope of delivery)
Device-specific data:
 Specify the format of the cyclical input/output data
– Specify the cyclically alternating process data using objects "Poll I/O input data
(4.0.100)" and "Poll I/O output data (4.0.101)"
– The format can be changed only if the poll I/O connection is inactive.
 Specify system behaviour following termination of the cyclical DeviceNet communica-
tion.
– Use object "Idle Action (9.1.7)" to specify which action is to be carried out if there
is a failure of the cyclical exchange of process data (poll I/O connection).
 Specify the remote priority.
– Use object "Permission locked (101.0.17)" to specify whether the electronic drive
unit is to be controlled exclusively via DeviceNet or whether other interfaces (e.g.
RS485) are also permitted.
– This does not restrict write access via other interfaces.
 Perform pump configuration.
– To set a configuration that differs from the delivery state, use the EDS file to adjust
individual objects (e.g. accessory configuration).
Master-specific data:
 Set up the device in the master scanlist.
 Set the format of the cyclical input/output data
Explicit data ex-
change (explicit con-
nection)
This connection can be used to access the individual DeviceNet objects
(see p. 16, chap.
6.5)
. As a rule, this is done using a dedicated configuration program and the EDS file.
This is also used to specify which data is sent during the cyclical data exchange.
