Introduction

The Fife SBPC-21-PB (Serial Bus Protocol Converter) provides a gateway between Fife’s proprietary

FifeNet network and Profibus™. Using the SBPC-21-PB, data originating from FifeNet can be sent on

Profibus and data from Profibus can be sent to FifeNet.

Profibus DP Overview

The supported media for the SBPC-21-PB Profibus is a shielded copper cable consisting of a twisted

pair. The baud rate for the bus is between 9.6K baud to a maximum 12M baud. The Profibus DP

network is able to carry 126 nodes and the total amount of data for Profibus DP is 244 bytes out per

module and 244 bytes in per module. Node 126 is only used for commissioning purposes and should

not be used to exchange user data. An example of a Profibus network with an SBPC-21-PB is shown

in the diagram below.

• 9.6 kbit/s up to 12 Mbit/s, maximum distance 200m at 1.5 Mbit/s extendible with

repeaters.

Medium Access: Hybrid medium access

protocol according to DIN 19245, Part 1

• Monomaster or multimaster systems supported.

• Master and slave devices, maximum 126 stations possible.

Communications: Peer-to-Peer (User Data

Transfer)

or Multicast (Synchronization)

• Cyclic master slave transfer and acyclic master-master data transfer.

Operation Modes

• Operate: cyclic transfer of input and output data.

• Clear: inputs are read and outputs are cleared.

• Stop: only master-master functions are possible.

Synchronization: Enables synchronization of

the inputs and/or outputs of all DP slaves.

• Sync-Mode: Outputs are synchronized.

• Freeze-Mode: Inputs are synchronized.

Functionality

• Cyclic user data transfer between DP-Master(s) and DP Slave(s).

• Activation or deactivation of individual DP Slaves.

• Checking of the configuration of the DP Slaves.

• Powerful diagnosis mechanisms, 3 hierarchical levels of the diagnosis messages.

• Synchronization of inputs and/or outputs.

• Address assignments for the DP-Slaves over the bus with Master Class 2.

• Configuration of the DP-Master (DPM1) over the bus.

• Maximum 244 bytes input and output data per DP Slave, typical 32 bytes.

Security and Protection Mechanisms

• All messages are transmitted with Hamming Distance HD=4

• Watchdog timer at the DP slaves.

• Access protection for the inputs/outputs at the DP slaves.

• Data transfer monitoring with configurable timer DP Master (DPM1).

Cabling and Installation • Connecting or disconnecting of stations without affecting of other stations.

Producer/Consumer Model

The Producer/Consumer Model allows the exchange of information between a sending device

(“producer”) and many receiving devices (“consumer”) without requiring the same data to be sent

multiple times to different destinations. The producer sends the data once and each consumer on the

network receives the data at the same time. The data can be used (“consumed”) or ignored by each

receiving device independently. FifeNet uses the Producer/Consumer Model.

FifeNet

FifeNet’s deployment of the Producer/Consumer Model allows data sent by a single device to be

received simultaneously by multiple devices on the same network. Each receiving device can choose

to use (“consume”) the information or ignore it as its needs dictate. FifeNet is based on a fixed time

slicing architecture where transmitting devices send data in fixed, predetermined time intervals.

SBPC-21-PB Switch/Jumper Configuration

Since the SBPC-21-PB participates in two networks at the same time, it must have two network

addresses (a FifeNet address and a Profibus node address). The FifeNet address is set via the

FifeNet serial port, which is common with many FifeNet peripherals. The Profibus master sets the

baud rate for the Profibus network. If the SBPC-21-PB is installed as the end point in a FifeNet

network, the jumpers shown below should be installed to provide network termination.

Figure 2-2: SBPC-21-PB Top View

These jumpers should be installed if the

SBPC-21-PB is at the end of a FifeNet

network. They provide network

termination. The other two jumpers

should always be installed as they

select half-duplex FifeNet

communication.

Terminated Not Terminated

The 7-segment LED is

used to display errors or

exceptions. During normal

operation, the display will

continuously “cycle” the

outer segments.

Profibus node address switches.

See the following page for

description of these switches.

Profibus Termination

The end nodes in a Profibus DP network must be

terminated to avoid reflections on the bus line. To

accomplish this, the Profibus DP module is equipped

with a termination switch. If the module is used as the

first or last module in a network, the termination switch

must be in the ON position. Otherwise, the switch

must be in the OFF position. If an external termination

connector is used, the switch must be in the OFF

position.

The termination dip switch can only be accessed with

the SBPC-21-PB top cover removed. To enable

termination, the switch must be in the OFF position.

Termination Switch Position

OFF Up toward top cover.

ON Down toward circuit board.
