1 Prerequisites
The pump can be enhanced with the 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
‘Field bus’
and the status bar shows the PROFIBUS®
symbol.
The pump must have the software version V01.01.00.00
or higher in order for the PROFIBUS® module to func‐
tion. If it is not working, the LED on the PROFIBUS®
module slowly flashes red and green.

2 Adjusting the pump
2.1 General
The pump with the plugged-in PROFIBUS® module is adjusted 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 the slave address
The address is pre-set to “125”. If a master in the PROFIBUS® segment
assigns the slave addresses, manual setting of the slave address is can‐
celled.
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 number using the
[Clickwheel]
and press the
[Priming]
key.
ðThe 2nd number of the address is marked.
2. Set the 2nd number using the
[Clickwheel]
and press the
[Priming]
key.
ðThe 3rd number of the address is marked.
3. Set the 3rd number using the
[Clickwheel]
and press the
[Clickwheel]
.
2.3 Switch PROFIBUS® to active / inactive
In order for the pump to be controlled using the PROFIBUS®,
‘Fieldbus’
must be set to
‘Active’
in the operating menu:
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, metering monitor and external
control (pause, contact input, analogue input), will continue to function
while the PROFIBUS® is
‘active’
. They result in the reactions that would
be expected with the pump without the PROFIBUS® module being plugged
in - see “Operating instructions for diaphragm motor driven dosing pump
Sigma X Control type SxCb”. The pump transmits corresponding informa‐
tion via the PROFIBUS® to the master (PLC Programmable Logic Con‐
troller, PC etc.).
If the PROFIBUS® is set to
‘Inactive’
, the settings for the previously
selected operating mode 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® operation
3.1 General
The pump cannot be manually set or programmed in
PROFIBUS® operation! To do this, set the PROFIBUS®
to ‘Inactive’ .
nUsing the
[Clickwheel]
it is possible to switch between the continuous
displays 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 linked to the PROFIBUS®. Only the total number of strokes
and the total number of litres continue to be counted and saved.
nIf the pump is switched to PROFIBUS® operation, it stops and can
only be restarted using the PROFIBUS®.
3.2 Displays
There are additional identifiers in the operating display when PROFIBUS®
operation is running.
The current identifiers can be found in the "Control ele‐
ments" chapter in the "Operating instructions for dia‐
phragm motor driven dosing pump Sigma X Control
type ...”.
Stop PROFIBUS®: The pump has been stopped by the 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.

3.4 Using the metering monitor
The "Metering monitor" socket must be assigned to use the metering mon‐
itor in PROFIBUS® operation. The pump then transmits
‘available’
for the
"Flow" status bit. The metering monitor can be switched on and off via the
PROFIBUS® using the
‘Flow control’
parameter - see “Operation” chapter.

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
device with slave functionality in conformity with DP-V1. This means that
the payload is transmitted both cyclically and acyclically.
5.2 GSD file
The GSD file must be used for configuring the master. It describes all fea‐
tures of the pump in PROFIBUS® operation (keywords, diagnosis, mod‐
ules, slots). The GSD file can be downloaded from the PROFIBUS® web‐
site and from the ProMinent website. The file name is clearly indicated:
PROM0B02.GSD
5.3 Description of the data objects
The initial parameters must be transmitted from the
master so that the pump can participate in cyclic data
transmission. Only standard parameterisation 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. For an example based
on “Status” - refer to the section below:
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.
