1 Supplementary instructions PROFIBUS® DP
1.1 Requirements
Personnel must be familiar with the contents of the "Assembly and
Operating Instructions for DULCOMETER® Multi-parameter Con‐
troller diaLog DACa".
The controller must have a PROFIBUS® DP module.
These supplementary instructions are only valid when used in con‐
junction with the operating instructions for the multi-parameter con‐
troller diaLog DACb.
1.2 Adjusting the controller
1.2.1 General
The controller with PROFIBUS® DP functionality is adjusted in the
same way as the standard controller, with the addition of the bus
functionality.
Adjustment process cancelled
In the event of a pause longer than 60 s, the
adjustment process is cancelled.
1.2.2 Configuring the PROFIBUS® DP
In order to control the controller using the PROFIBUS® DP, you
must activate the PROFIBUS® DP in the controller operating menu
(see the controller operating instructions).
While the PROFIBUS® DP is active, all external inputs will function.
The external inputs lead to the expected reactions as in the case of
the controller without PROFIBUS® DP functionality (see controller
operating instructions). The controller sends corresponding infor‐
mation over the PROFIBUS® DP to the master (PLC, PC etc.).
Even if the fieldbus is set to inactive, the master is able to read-
access the controller data defined in its GSD file.
If the PROFIBUS® DP is inactive or set to inactive, the settings for
the operating mode selected prior to "inactive" status are reloaded
in the controller.
If the controller is switched to another operating mode, it stops and
can only be restarted using the
[Stop/Start] key.
1. To access the ‘Menu’ : press the [Menu] key
2. Use the cursor keys to select the menu item ‘Setup’ and
confirm with the [OK] key
ðThe menu
‘Device setup’ appears.

tions

3. Use the cursor keys to select the menu item ‘Bus
Configuration ’ and confirm with the [OK] key
ðThe
‘Configuration’ menu appears.
4. In the ‘Configuration’ menu, you can:
n
‘Remote configuration’
– Activating/deactivating remote configuration.
n ‘Address’
– Here you can set the address at which the controller
in the bus can be accessed.
n ‘Termination’
– Here you can set whether the controller is the last
device in the bus and whether or not the terminating
resistance is activated.
1.3 Special features in active PROFIBUS® DP operation
1.3.1 General
Setting and programming
In PROFIBUS® DP operation, the controller cannot
be manually set or programmed. To set or pro‐
gramme the controller, set the PROFIBUS® DP to
‘inactive’ .
nWhen PROFIBUS® DP operation is selected, the settings from
the last operating mode without PROFIBUS® DP are applied.
By contrast, the settings made via the PROFIBUS® DP are not
saved. These only apply as long as the controller is linked to
the PROFIBUS® DP.
nIf the controller is set to PROFIBUS® DP operation, it stops.
The controller can be controlled again by pressing the
[Stop/Start] key. The start command is given via the PRO‐
FIBUS® DP module.
1.3.2 Display
In running PROFIBUS® DP operation there are further identifiers in
the operating indicator.
Common identifiers
The common identifiers are described in the con‐
troller operating instructions.

Signal Cause
Off The module has no supply voltage or connection.
Green The module and the master are exchanging information.
Green flashing The module has been initialised.
Red flashing Error in pump parametrisation
Red flashing, double Error in PROFIBUS configuration
Signal Cause
Off The module has not been initialised.
Green The module has been initialised.
Green flashing The module has been initialised and there are diagnostic mes‐
sages.
Red Serious exception error
1.4 Installation
All devices that are members of the bus system must be connected
in a line. There are up to 32 possible stations (master, slaves,
repeaters).
At both the beginning and end of the cable, the bus must be termi‐
nated with a terminating resistance.

For the PROFIBUS® DP cable, use a screened, twisted-pair cable
conforming to EN 50170 (cable type A).
Earthed shielding
Using shielding which is earthed at one end pre‐
vents low-frequency ground loops. Shielding
earthed at one end is not effective in countering
HF magnetic pick-up. Shielding earthed at both
ends as well as twisted conductors are effective in
countering magnetic HF pick-up but are not effec‐
tive against electrical HF pick-up.
For PROFIBUS®, we would recommend establishing a bilateral,
low-inductance (i.e. large area and low-impedance) connection
with the protective earth.
Tab. 2: The maximum overall length of the bus cabling without repeaters varies according to the desired data
transmission rate:

100 12000
100 6000

200 1500
400 500
1000 187.5
1200 93.75
1200 19.2
1200 9.6
The PROFIBUS® DP cable is fitted directly on the terminals of the
PROFIBUS® DP module.
An installation conforming to IP 67 is possible because the cabling
is carried out using the appropriate assembly accessories (cable
passages etc.) directly on the controller terminal.
CAUTION!
Degree of protection IP 67
– IP 67 degree of protection only applies if the
appropriate assembly accessories (cable pas‐
sages etc.) have been correctly installed (see
controller assembly and operating instructions).
If the controller is the last bus device connected to the PROFIBUS®
DP cable, it must be connected as a termination using the PRO‐
FIBUS® DP module (see EN 50170). The terminating resistance
required for this can be activated internally using the ‘Termination’
operating menu (network termination). No external terminating
resistance is required.

1.5 Operation
1.5.1 General
Using the connected PROFIBUS® DP module, the PROFIBUS® DP
controller represents a device with slave functionality in conformity
with DP V1. This means that the payload is transferred both cycli‐
cally and acyclically.
1.5.2 GSD file
The GSD file must be used for configuring the master. The GSD
file describes all of the features of the pump in PROFIBUS® DP
operation (keywords, diagnosis, modules, slots). The GSD file can
be downloaded from the PROFIBUS® website and from the ProMi‐
nent website. The file name is clearly indicated: DACB101C.gsd .
