3. Introduction

The FD-10 is a PROFIBUS DP slave unit that is able to transfer PROFIBUS DP data via leased lines,dialup modems or radio systems.The FD-10 is used to interface different PROFIBUS DP networks.

All Westermo Fieldbus Adapters use the same protocol to communicate with each other via serial interface.

3.1 Device types

There are three different types of FD-10 devices described in this manual:

• FD-10 P Point to point and Addressed, serial transfer slave

• FD-10 A Addressed,serial transfer master

• FD-10 N Network, serial sending

All device types are based on the same hardware architecture, schematically shown below.

3.2 When are FD-10 devices useful?

Where a PROFIBUS DP net require connection to one or some PROFIBUS DP units which are so located,that they:

• can’t be included in the net due to the distance,or

• reduce PROFIBUS DP data rate below the rated required for the system,or

• disturbance in PROFIBUS DP line (transmission line)

FD-10 will,together with the transfer units (modem), act as a interconnecting line between two or many PROFIBUS DP nets.The interconnection line protocol handle retransmission due to disturbances (e.g.due to the use of radio network or moving trolleys),without any limitations at the PROFIBUS DP net.From the PROFIBUS DP master point of view the whole system will be seen as a single PROFIBUS DP net,while the master has all PROFIBUS I/O data handling with FD-10.

3.3 Field of application

Between Fieldbus adapters is PROFIBUS DP I/O data transferred over a transmission line, divided in following type of applications:

• Point to point transfer

Continuous transfer of defined PROFIBUS I/O data modules between two FD-10’s. This application is ideal when a high speed update of PROFIBUS DP data is required and where no additional measures at installation is desired.

This application is realised by two FD-10 P (point to point mode) with an interconnecting line and modems,if required.

• Master controlled transfer (Addressed)

One transfer of defined PROFIBUS I/O data modules between two FD-10’s, on demand from a PROFIBUS DP master. One FD-10 act as serial transfer master and can transfer I/O data between various FD-10’s,selected by serial transfer address.This application is ideal when a PROFIBUS DP master need connection to two,or more,independent remote PROFIBUS DP systems.Radio system or RS-485 is typically used as transfer line. Required additional measures,as serial transfer addressing.

This application is realised by one FD-10 A and one or many FD-10 P (addressed serial transfer slave mode) with an interconnecting line and modems,if required.

7.3 Network,serial sending, FD-10 N

Send PROFIBUS in data from one FD-10 to an other FD-10 to be set as PROFIBUS out data,on demand (event) by the PROFIBUS DP master in the sending PROFIBUS DP net. One of the included FD-10’s can send I/O data to any other FD-10,selected by serial transfer address.Note that the first data word,command output and one data word status input has to be included in PROFIBUS I/O data of FD-10.

Arbitrary FD-10 can send a frame to an other FD-10 at any time.This serial addressing enable access to up to 64 independent remote PROFIBUS DP nets by only one serial transmission line (e.g. radio system or RS-485).To reduce collisions on the transmission line, the frequency or time between events resulting in sending has to be limited. The degree of limitation depend on the number of FD-10’s and data rate of the serial transfer.

FD-10 can send frames when the unit is in normal operation mode and the PROFIBUS DP is active,LED CONF inactive and BA active.
