1 Requirements

The pump can be enhanced with PROFIBUS® functionality by means of a

plug-in module. To do this, insert the plug-in module into the front of the

pump (similar to a relay module). The operating menu then displays the

menu item

‘Fieldbus’

and the status bar shows the PROFIBUS® symbol.

The pump must have the software version V04.03.02.00

or higher for the PROFIBUS® module to work. If it is not

working, the LED on the PROFIBUS® module slowly

flashes red and green.

Requirements

2 Setting up the pump

2.1 General

The pump with the plugged-in PROFIBUS® module is set up in the same

way as the standard pump, with the addition of the bus functionality.

The pump interrupts the set-up process in the event of

pauses longer than 60 s.

2.2 Setting up the slave address

The address is pre-set to “125”. There is no need to manually set up the

slave address if a master in the PROFIBUS® segment assigns the slave

addresses.

1. Press the

[Menu]

key.

2. Turn the

[Clickwheel]

‘Fieldbus’

and press the

[Clickwheel]

3. Turn the

[Clickwheel]

‘BUS Address’

and press the

[Clickwheel]

Always enter the PROFIBUS® address as 3 digits (addresses between

“002” and “125”):

1. Set the 1st digit using the

[Clickwheel]

and press the

[Priming]

key.

ðThe 2nd digit of the address is highlighted.

2. Set the 2nd digit using the

[Clickwheel]

and press the

[Priming]

key.

ðThe 3rd digit of the address is highlighted.

3. Set the 3rd digit using the

[Clickwheel]

and press the

[Clickwheel]

2.3 Switching PROFIBUS® to active / inactive

‘Fieldbus’

must be set to

‘Active’

in the operating menu for the pump to

be controlled using the PROFIBUS®:

1. Press the

[Menu]

key.

2. Turn the

[Clickwheel]

‘Bus active’

and press the

[Clickwheel]

3. Turn the

[Clickwheel]

‘Active’

‘Inactive’

and press the

[Clickwheel]

. You’re done!

All external inputs, such as level monitoring and external control (pause,

contact input, analogue input), will continue to function while the PRO‐

FIBUS® is

‘active’

. They result in the reactions that would be expected

with the pump without the PROFIBUS® module being plugged in - refer to

“Operating instructions for the peristaltic pump DULCO flex Control -

DFYa”. The pump transmits relevant information via the PROFIBUS® to

the master (PLC, PC etc.).

If the PROFIBUS® is set to

‘inactive’

, the settings for the operating mode

previously selected are reloaded.

If the pump is switched to another operating mode, it stops and can only

be restarted using the

[Stop/Start]

key.

Setting up the pump

3 Special features in active PROFIBUS® mode

3.1 General

The pump cannot be manually set or programmed in

PROFIBUS® mode! To do this, set the PROFIBUS® to

‘Inactive’ .

nThe

[Clickwheel]

can be used to switch between the continuous dis‐

plays at any time, as in the other operating modes. This does not

affect the operation of the pump.

nThe settings from other operating modes are carried over when

switching over to PROFIBUS® operation. However, settings made

using the PROFIBUS® are not saved! They only apply as long as the

pump is connected to the PROFIBUS®. Only the total number of revo‐

lutions and the total number of litres continue to be counted and

saved.

nIf the pump is switched to PROFIBUS® mode, it stops and can only be

restarted using the PROFIBUS®.

3.2 Displays

There are additional identifiers in the operating display when PROFIBUS®

mode is running.

The commonly used identifiers can be found in the “Con‐

trols” chapter in the “Operating instructions for the peri‐

staltic metering pump DULCO flex Control - DFYa”.

Stop PROFIBUS®: the pump has been stopped using PROFIBUS®.

The master has sent the pump a corresponding telegram.

Connection error: If the pump loses its connection to the PROFIBUS®

(for instance as soon as the PROFIBUS® is stopped), an error message

with the symbol appears on the main display.

Special features in active PROFIBUS® mode

4 Installation

All devices that are members of the bus system must be connected in a

line. There are up to 32 possible positions (master, slaves, repeaters).

At both the beginning and end of the cable, the bus must be terminated

with a terminating resistance.

For the PROFIBUS® cable, use a screened, twisted-pair cable in con‐

formity with EN 50170 (cable type A).

Use of shielding which is earthed at one end prevents

low-frequency ground loops. Shielding earthed at one

end has no effect in combating HF magnetic pick-up.

Shielding earthed at both ends as well as twisted con‐

ductors work to counter magnetic HF pick-up, but have

no effect against electrical HF pick-up.

For PROFIBUS®, it is recommended to establish a bilateral, low-induc‐

tance (i.e., large area and low-impedance) connection with the protective

earth.

The overall length of the bus cabling without repeaters varies according to

the desired data transmission rate:

Tab. 1: Data transmission rate and length of the bus cabling

Data transmission rate Maximum length of bus cabling

kBit/s m

1500 200

500 400

187.5 1000

93.75 1200

19.2 1200

9.6 1200

The PROFIBUS® module has a M12 industry socket for connection to the

PROFIBUS® cable. The pin configuration complies with the PROFIBUS®

standard - see below - which means that commercially available bus plugs

may be used. Please note that cable connections made with these plugs

generally only meet the requirements for protection against contact and

moisture according to IP 20!

An installation compliant with the protection against contact and moisture

according to IP 65 is possible, since the M12 industry socket of the PRO‐

FIBUS® module allows this. However, in this case the PROFIBUS® cable

must also be fitted with M12 industry plugs in conformity with IP 65.

In order to achieve the IP 65 degree of protection for the PROFIBUS®

cable installation, special Y-adapters or terminating adapters must be

installed (e.g. - see below).

Plugs and cables

Note for achieving IP 65 degree of protec‐

tion

Installation

CAUTION!

– Degree of protection IP 65 applies only to a plug/

socket combination that has been screwed together!

–In ambient conditions requiring protection against

contact and moisture according to IP 65, cables with

moulded M12 industry plugs must be used (e.g., see

below).

– Degree of protection IP 65 applies only to an

unwired pump (with PROFIBUS® module) if an IP

65-capable cover is placed over the M12 industry

socket! The cover included in the delivery does not

guarantee chemical resistance.

5 Shielding

Y-adapter (order no. 1040956)

The Y-adapter connects to the pump using a moulded M12 plug. The ends

are provided with an M12 plug and an M12 socket. The Y-adapter com‐

plies with the requirements for protection against contact and moisture

according to IP 65.

PROFIBUS® termination, complete (order no. 1040955)

If the pump is the last bus device connected to the PROFIBUS® cable, it

must be connected completely as a termination using the PROFIBUS® ter‐

mination - see EN 50170. The PROFIBUS® termination, complete, com‐

plies with the requirements for protection against contact and moisture

according to IP 65. (It consists of a Y-plug and terminating resistance.)

Installation

5 Operation

5.1 General

The plugged-in PROFIBUS® module make the PROFIBUS® pump a unit

with slave functionality in compliance with DP-V1. This means that the

usage data is transmitted both cyclically and acyclically.

5.2 GSD file

Use the GSD file to configure the master. It describes all features of the

pump in PROFIBUS® mode (keywords, diagnostics, modules, slots). The

GSD file can be downloaded from the PROFIBUS® website and from the

ProMinent website. The file name is unique: DFYA1180.GSD

5.3 Description of the data objects

The initial parameters must be transmitted from the

master so that the pump can engage in cyclic data trans‐

mission. Only standard parametrisation is needed for

this – there are no application-specific parameters.

Please note: Data is stored according to the “Big-

Endian” principle! This means that the byte with the

highest-value bits is stored first at the memory location

with the lowest storage address. Refer to the section

below for an example based on “Status”:

The pump status is stored as UINT32 type at the offset addresses +0 to

+3. Bytes are stored in this sequence:

Name Type Offset Byte Bits

Status UINT32 +0 0 24 ... 31

+1 1 16 ... 23

+2 2 8 … 15

+3 3 0 … 7

All the data objects that can be cyclically transmitted are described below.
