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.

Validity of the supplementary instruc‐

tions

Supplementary instructions PROFIBUS® DP

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:

‘Remote configuration’

– Activating/deactivating remote configuration.

‘Address’

– Here you can set the address at which the controller

in the bus can be accessed.

‘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.

Supplementary instructions PROFIBUS® DP

1.3.3 LEDs on the PROFIBUS® DP module

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.

LED 2 (right) - module status

Bus installation

Supplementary instructions PROFIBUS® DP

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 6000

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 .
