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. Unscrew the cross recessed head screws in the blind cover.

2. Remove the blind cover.

Field bus module

Fig.3: Inserting the field

bus module

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

module

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.
