1INTRODUCTION

1.1 General

These Instructions are supplementary to the “MFC300 (OPTIMASS) Handbook”. You must follow

that handbook in particular the Safety Information These Supplementary Instructions provide

additional information for device operation and connection to a PROFIBUS fieldbus.

1.2 Items included with supply

In addition to the standard scope of supply, these Supplementary Instructions for the MFC300

PROFIBUS RS-485 Interface will be included.

1.3 Special Notes

•Don’t switch off (power off) the MFC300 immediately after manual change of parameter val-

ues:

•Please wait approx. 10 seconds before you switch off the MFC300 after you have done

both a parameter download via PROFIBUS or a manual change of a parameter value

via the local display.

•Please wait approx. 15 sec before you switch off the MFC300 after you have carried

out a “Factory Reset” (PROFIBUS “Coldstart”) via PROFIBUS or local display.

•“Deactivation of the Service Parameter Lock” of the MFC300 via PROFIBUS:

•After writing down the service password (via PROFIBUS) the “Deactivation of the

Service Parameter Lock” will last at least 10 min. if the internal password timer of

the MFC300 won't be retriggered by writing this password again. The “Deactivation of

the Service Parameter Lock” will be terminated at once by a PROFIBUS Cold-/Warm-

Start or if the internal password timer of the MFC300 elapsed.

For a detailed description of the electrical connections of the MFC300 please refer to the OPTI-

MASS Handbok.

The illustration above shows a typical instrumentation with PROFIBUS devices with RS-485

interface in non-hazardous locations. The PROFIBUS devices with RS-485 interface do not

need any segment coupler. They can be connected directly to the PROFIBUS DP Network.

Please also refer to publication: “

Installation Guidelines for PROFIBUS DP/FMS

” (PNO Order

Number 2.112/2.111)

2.4 GSD Files

Supported baud rates are listed in the GSD file (see below). After power-on or PROFIBUS time-

out a baud rate search is active to detect the current transfer speed on the bus. It is not neces-

sary to set the baud rate manually.

If the transfer speed is changed during operation the baud rate search will not be started by

the device. A new power-up or a manual interruption of the PROFIBUS communication is

required to activate the baud rate search in this case.

A “PROFIBUS GSD ZIP” file (e.g. GSD-31777815.zip) including both all KROHNE GSD files and

additional data files can be downloaded from the KROHNE homepage http://www.krohne.com

or contact “KROHNE Marketing”. The GSD file contains information that will be needed for

project planning of the PROFIBUS DP communication network. The relevant data files (e.g.

MFC300_n.bmp; MFC300_n.dib) must be loaded into the bus configuration system/master sys-

tem before start-up of the bus system.

The MFC300 PROFIBUS RS-485 Interface is according to the PROFIBUS PA Profile V 3.01. The

device supports two Ident-No:

•Ident-No. “4510hex” belongs to the GSD file KR014510.GSD and includes the complete func-

tionality concerning the cyclic data exchange of the coriolis mass flow meter MFC300.

•The application of the manufacturer independent Ident-No. “9742hex” (GSD file

“PA039742.GSD”) provides interchangeability of devices, i.e. an exchange of coriolis mass

flow meters of different vendors.

Please follow the instructions in the manual of the host supplier when installing the GSD File

you need and the additional files (MFC300_n.bmp and MFC300_n.dib) into the PLC. If separated

by the bus configuration system the device entry of the MFC300 PROFIBUS RS-485 Interface

with PA Profile 3.01 will be located within the slave family PROFIBUS PA.

control data from master to the device via the parameters SetTot and

ModeTot (in the given order)

“SetTot” cyclic control data from master to the device via the parameter SetTot

“ModeTot” cyclic control data from master to the device via the parameter ModeTot

“SetTot + ModeTot” cyclic control data from master to the device via the parameters SetTot

and ModeTot (in the given order)

The Byte SetTot and ModeTot are being sent cyclically from the Master to the device if these

bytes are inserted as output data via the PLC configurator. The meaning of these control bytes

are as follows:

AI = Analog Input Function Block

FB = Function Block

There are separate settings to select the units for local display and PROFIBUS. Modifications of

the units of the display will have no effect on the data transferred via PROFIBUS. A master

class 2 tool is required to modify the units for PROFIBUS transfer.

During network configuration the user has to define which function block outputs of the

MFC300-DP should be transferred cyclically to the master. This is done by a bus configuration

tool (e.g. for PC-S7 from Siemens this will be done with the tool “HW- Config”). This tool offers

the functions described as follows:

1. It is possible to configure an “Empty” block (the code of an “Empty” block is defined as

0x00) on each block number. This means, that for this block no data is transmitted in the

cyclic data telegram.

2. There is NO “Totaliser (TOT)” function block allowed on block position 1, 2, 3, 7, 8, 9, 10 and

11! An “Analog Input (AI)” function block or an “Empty” block is allowed here only!

Note: All codes supported of “Analog Input (AI)” - and “Totaliser (TOT)” – function blocks will

be found in the corresponding GSD files.

3. There is NO “Analog Input (AI)” function block allowed on block position 4, 5 and 6! A

“Totaliser (TOT)” function block or an “Empty” block is allowed here only!

4. There is a choice of 7 different totaliser functions, which can be allocated to the blocks 4, 5

and / or 6. The 7 functions are defined as follows:
