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] to ‘Fieldbus’ and press the [Clickwheel] .
3. Turn the
[Clickwheel] to ‘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] to ‘Bus active’ and press the [Clickwheel] .
3. Turn the [Clickwheel] to ‘Active’ or ‘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.

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.

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).

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.

.
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.)

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.
