1 Supplementary Operating Manual
1.1 General
This supplementary operating manual accompanies the installation/operating
manual. All information contained in the installation/operating manual must be
observed.
Table1: Relevant operating manuals
Type series Reference number of the operating/installation
manual
PumpDrive 2 4074.81
1.2 Function
The Profibus field bus module serves to connect PumpDrive2 to a Profibus network.
A Profibus module is required for monitoring and open-loop or closed-loop control
purposes for each frequency inverter in single-pump configuration or multiple pump
configuration.
Interface The Profibus module is equipped with a Profibus interface with ProfibusDP protocol
in accordance with the "Profile for Intelligent Pumps" version1.0 specification.
Configuration is done via frequency inverter parameters.
Communication protocol Profibus DP
Bus terminator External
Interface EIA-485 (RS485)
Transmission rate Automatic, 9600-12Mbit/s
Device type Slave
For information on Profibus and downloads for PROFIBUSDP and the "Profile for
Intelligent Pumps" please go to www.Profibus.com.
For further accessories for the Profibus module, such as M12 connectors and
terminating resistors please refer to the type series booklet.
GSD file The characteristic communication configuration data of the frequency inverter, such
as the number of input signals and output signals, diagnosis messages, etc. are
described in an electronic general station description (GSD) file.
The GSD file can be read by a Profibus configuration tool, which is then used to
configure the Profibus Master. The GSD file is a PROFIBUSDPstandard text file,
available for download from the KSB website.
1.3 Field bus module connections
The field bus modules are plug-in modules.

1. Carefully insert the field bus module into the open slot. The plug-in module is
guided on rails until it engages in the contact.
Fig.4: Securing the field bus

2. Secure the field bus module using the 4 cross recessed head screws. IP55
enclosure protection is not provided until the screws have been tightened.
CAUTION
Incorrect assembly
Impairment of protection provided by the enclosure (protection may be
compromised)!
▷Cover unused M12 connections with a cap (included in the scope of supply).

1.5 Connecting the field bus module
For connecting the field bus module observe the installation guide of the Profibus
user organisation (PNO) (download from "http://www.profibus.com/download/
installation-guide/"). Pay particular attention to the following:
▪Before the bus connection is established among the nodes, potential equalisation
must have been implemented and checked.
▪For high-frequency shielding, use shielded cables and assemble according to EMC
requirements.
▪A minimum distance of 0.3metres is recommended between such cables and
other electric conductors.
▪Do not use the bus cable to make any further connections in addition to the field
bus module (for example, 230V alert and 24V start).
▪A cable specified for the field bus module must be used as the connecting cable.
CAUTION
Incorrect installation
Damage to the field bus module!
▷Never supply power to the field bus module via the M12 connections.

Fig.10: Bus terminating resistor M12
The field bus terminating resistor can be plugged directly into the M12 socket. Bus
polarisation does not take place if the field bus module is de-energised. If the bus
terminator is to be independent of the field bus module power supply, it must be
implemented externally using an active bus terminator.
NOTE
The frequency inverter is reset when a field bus module is replaced or retrofitted.
Menu 3-12 for setting the parameters of the field bus module is then enabled in the
control panel.
1.6 Setting the parameters of the field bus module
Field bus control must be activated in the frequency inverter when using the field bus
module.
Settings for the Profibus Slave address and the control point are made at the control
panel of the frequency inverter.

Parameter Description Possible settings Factory setting
3-12-1-3 Cycle time, setpoint/control value
Time delay before the message (warning or
alert) is triggered. In a redundant system, only
a warning is output as the auxiliary master can
assume the function. Only if the setpoint/
control value also fails at the auxiliary master is
the alert output, which then triggers the
specified response to setpoint/control value
failure.
0.0...10.0 5
3-12-1-4 Cycle time, actual value
Time delay before the message (warning or
alert) is triggered. In a redundant system, only
a warning is output as the auxiliary master can
assume the function. Only if the actual value
also fails at the auxiliary master is the alert
output, which then triggers the specified
response to actual value failure.
0.0...10.0 1
NOTE
If the field bus is only used for monitoring purposes, the Control Point parameter
(3-6-2) is set to Local.
NOTE
If the cycle times of parameters 3-12-1-3 and 3-12-1-4 are set to 0seconds, the
monitoring function for each of these parameters is disabled.
1.7 Frequency inverter operation with Profibus module
The function and the commissioning procedure described below for the frequency
inverter are based on the device profile and communication profile "Profile for
Intelligent Pumps Version1.0 November2007" (PIP), edition for centrifugal pumps
("Rotodynamic pump"), issued by the Profibus user organisation (PNO).
Profibus for PumpDrive2 is defined as a DPSlave of device type "Drive" and can be
addressed by a class1 or class2 DPMaster.
The Profibus implementation supports the cyclic exchange of I/O data as part of the
MS0 communication relationship and the acyclic services Read/Write (PI function
blocks RDREC and WRREC) as part of the MS1 communication relationship.

Profibus module
1.7.2 Definition of the "rotodynamic pump” module available in the cyclic data
exchange
The Rotodynamic Pump module serves to enter setpoints and control values for the
pump set in a compact form. It also provides key information on the current
operating status.
A variety of data types is used within the address range of the module. Binary
information and requests in the module are bit-coded; the other data points are
transmitted as integer values.
The Rotodynamic Pump module is the most important data point for control of the
frequency inverter and is structured as follows:
▪Rotodynamic Pump Input = 6Byte (Byte, Byte, Word, Byte Byte)
▪Rotodynamic Pump Output = 5Byte (Byte, Byte, Byte, Word)
NOTE
Depending on the make of PLC, pay special attention to the area of the memory
into which the Rotodynamic Pump module must be integrated.
Consistency on the part of the Rotodynamic Pump module can only be ensured if the
module is located in the process image area or if the module is copied into or out of
a buffered area by special system modules. The Rotodynamic Pump module contains
bit variables, byte variables and word variables. This does not apply to the process
variable view. A process image is not required as byte operations, word operations or
double-word operations are provided there which ensure the module's consistency.
