Prerequisites

The pump can be enhanced with the PROFIBUS® 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 symbol.

‘Field bus’

and the status bar shows the PROFIBUS

functionality by means

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.

2.2 Setting the slave address

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.

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.

Installation

4 Installation

Bus installation

Plugs and cables

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:

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).

Page 9

CAUTION!

P_DE_0073_SW

– 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.)

Operation

5 Operation

General

5.1

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

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 "BigEndian" 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

It is possible to select on the master which modules are to be involved in cyclic data transmission. Modules and slots always relate to each other. Empty spaces (empty modules) therefore have to be configured for mod‐ ules to be excluded.

The target configuration is defined in the form of identifiers. The identifier is stated in the last column in for every defined module.

The identifiers of the modules have to be listed successively in ascending order. If the data of a module is not to be involved in cyclic data transmis‐ sion, then an empty module must be configured at this point.

The data objects can still be reached acyclically.

40 80 0 0 40 83 C0 80 83 0

The pump checks whether the target configuration corresponds to the actual configuration. If this is not the case, the pump reacts and sends a configuration error in the standard diagnostics.

In order for the target configuration to function, the options for the crea‐ tion of the identifier formats must be limited and the followings rules must be observed.

n Always use the special identifier format for the coding. n Always use the byte structure as the format. n Do not state any manufacturer-specific data (e.g., data types). n Modules must always be replaced with empty modules to remove

them from the cyclic data transmission.

By excluding individual modules from the cyclic data transmission, the offset addresses of the transmitted data objects will shift - see and :

The pump uses the mechanism of the extended PROFIBUS® diagnostics to report error statuses to the master. The extended diagnostics can be found in the diagnostics telegram. The extended diagnostics include the device-related "Alarm_Type (48)" and the "Diagnostic_User_Data".
