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.

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.

SBPC-21-PB External Connections/Switches/Indicators
SBPC-21-PB mounting considerations are simplified as all connections to the SBPC-21-PB are on the
same side of the box. The node address and rotary switches are accessible after removal of the plastic
hole plugs which should be reinstalled after configuration is completed.
Figure 1-3: SBPC-21-PB Side View
Profibus DP Baud Rate
The baud rate on a Profibus DP network is set during configuration of the master. Only one baud rate
is possible in a Profibus DP installation. The SBPC-21-PB uses auto baud rate detection so the user
does not have to configure the baud rate. Baud rates supported are:
• 9.6 kbit/s • 187.5 kbit/s • 3 Mbit/s
• 19.2 kbit/s • 500 kbit/s • 6 Mbit/s
• 93.75 kbit/s • 1.5 Mbit/s • 12 Mbit/s
Connection to FifeNet is
accomplished using the
standard FifeNet
connector. Configuration
is also downloaded using
this connection.
LED indicators provide
feedback for network
troubleshooting.
The Profibus Node address is set using these
rotary switches. This enables address settings
from 1-99 in decimal format. The left switch
sets the most significant digit and the right
switch sets the least significant digit. The node
address cannot be changed during operation.

SBPC-21-PB Error Codes
The 7-segment LED digit on the SBPC-21-PB main board is used to indicate errors or other potential
problems. See page 2 of this manual for the location of this LED. The error codes are divided into the
categories listed below. Since there is only a single-digit display and the error codes are 3 digits in
length, the error codes are displayed in three parts. The most significant digit will appear first followed
by the second and third digits. The display will go blank for a moment and the cycle repeats unless the
SBPC-21-PB has been configured to attempt to restart after an error. If this is the case, the error will
only cycle once. All state machine errors 5XX are considered nonfatal and only cycle once. Below are
the error codes and their meanings:
Table 1-2
SBPC PROCESSOR ERRORS
F01 Processor attempted to execute and undefined instruction.
F02 Software interrupt vector occurred.
F03 Attempt to fetch instruction from invalid memory.
F04 Attempt to read data from invalid memory.
F05 Reserved exception vector.
F06 FLASH memory checksum fault.
F07 Pool memory allocation error.
F08 Byte memory allocation error.
F09 Unable to create thread.
F0A Unable to create event.
F0B Unable to create semaphore.
F0C Unable to create mutex.
F0D Unable to create queue.
F0E Unable to write to queue.
F0F Console I/O error.
Errors that begin with ‘F’
are unrecoverable faults.
The SBPC cannot
participate in FifeNet or
Profibus operations. In
the default configuration
the SBPC will attempt to
restart.
COMMUNICATION MODULE ERRORS
E01 The configuration matrix is corrupted.
E02 No HMS Anybus module detected.
E03 Anybus module failed to initialize (no interrupt received).
E04 Anybus module failed to initialize (interrupt stuck).
E05 Anybus module failed to initialize (mailbox not ready).
E06 Anybus mailbox timeout.
E07 Anybus mailbox response indicated error.
E08 Anybus mailbox response timeout.
E09 Anybus dual-port RAM fault.
E0A Anybus output area release timeout.
E0B Anybus initialization timeout.
Errors that begin with ‘E’
are associated with the
Profibus interface. In the
default configuration, the
SBPC will attempt to
restart. With the
exception of error ‘E01,’
FifeNet is functional;
however, the default
configuration will attempt
to restart which will
interrupt FifeNet.
STATE MACHINE ERRORS
501 State machine file is corrupted.
502 State machine is disabled.
503 State machine started in shutdown mode.
504 Bad state machine instruction encountered.
505 State machine instruction fetch from address is out of range.
506 State machine stack error (too many nested calls).
507 State machine stack error (too many returns).
508 State machine attempted divide by zero.
509 State machine tried to access more than four timers.
50A State machine variable address is out of range.
Errors that begin with ‘5’
are related to the state
machine capability of the
SBPC. These errors are
cycled only once and do
not cause the SBPC to
restart.

FIFENET THEORY
• • • • • •
FifeNet Time Slices
Data on FifeNet is divided into time intervals called time slices. The FifeNet protocol runs in fixed
repeating cycles. Each time slice can transmit a single 16-bit value. All time slice values are updated
every cycle.
Multiplexed Time Slices
FifeNet devices can send a single 16-bit value in one or more time slices. This is acceptable for
values that require high performance such as guiding. The penalty for this performance is the usage
of one time slice per value sent. With limited time slices available, network bandwidth can be
consumed quickly. If some variables are not needed at a high rate, FifeNet offers a way to “multiplex”
a single time slice to carry multiple data words. There are two multiplex options available in the
CDP-01 permitting a single time slice to carry 16 words or 64 words. Multiplexing works by inserting
the specified data words in a sequential repeating cycle. The receiving SBPC-21-PB synchronizes
with the multiplexed data to extract it. This method trades data update speed for higher data quantities
(up to 64 words per time slice). Any combination of real-time or multiplexed data can exist on FifeNet.

MULTIPLEXING
D5 is multiplexed or switched to a
different variable every cycle.
After the last variable is sent, the
process repeats continuously.

________________________________________________________________________________________________________________
12-20-2002 Figure Sheet 1-851-A Page 10
In the example diagram (Figure 2-1), there is real-time data on D1 and 16 multiplexed data words on
D5. D1 contains the Edge Left Sensor value from a CDP-01. D5 is used to send 16 different values
from the CDP-01. For the real-time value, the CDP-01 sends the Edge Left Sensor value in D1 every
cycle. For the multiplexed time slice, the CDP-01 sends the Edge Right Sensor value in D5 during
time T0. During time T1, D5 contains the Line Edge Sensor value.
As you can see in the example on the previous page, 17 values are being sent over FifeNet, but only
two time slices of network bandwidth are used. The 16 values in time slice 5 are updated at a slower
rate than the value in time slice 1. The application dictates which method should be implemented.
FifeNet Master
The FifeNet protocol uses the time slice architecture described previously for configurable network
traffic. Without some synchronization, however, neither the SBPC-21-PB, nor the CDP-01, would
know where the time slice boundaries were located. This would create problems when they are trying
to send and receive data. This is one of the primary functions of the FifeNet Master, in this case, that
would be the SBPC-21-PB.
SBPC-21-PB Data Flow
In order to effectively connect two dissimilar networks, some means must be provided to collect the
data from each network and exchange it in a controlled manner so that no partial or incomplete data is
sent on either network. This is accomplished by using a block of memory in the SBPC-21-PB to
reassemble FifeNet time slice data and then, when it is complete, transfer it to the Profibus buffers for
transmission on Profibus. Keep in mind that the gateway has to be bidirectional so this process works
the same way for data traveling from Profibus to FifeNet. The diagram below shows the process:

As you can see in Figure 2-2, each time slice has enough memory to store 64 16-bit data words. This
is the maximum amount of data that appears on a FifeNet multiplexed time slice. These data words
are referenced by their order of reception in the multiplexed sequence with DW0 being first and DW63
being last. When the time slice is used in the real-time mode, only the first location DW0 in the
memory array is used. Multiplexed modes 4, 8, and 16 each use 4, 8, and 16 words of memory,
respectively.

Hardware Configuration - Single CDP-01
The SBPC-21-PB connection diagram is shown below. As you can see, this allows a single CDP-01 at
FifeNet address 1 and an SBPC-21-PB at FifeNet address 10. The SBPC-21-PB default Profibus
node address is 2, but can be easily changed using the rotary switches in the SBPC-21-PB.

Hardware Configuration - Multiple CDP-01’s
In the network below, the default SBPC-21-PB configuration is used multiple times to provide control to
multiple CDP-01’s. Each SBPC-21-PB is connected to a single CDP-01 creating a separate FifeNet
network for each CDP-01. Each SBPC-21-PB appears as both a FifeNet node and a Profibus node.
Notice the SBPC-21-PB Profibus address must be different for each SBPC-21-PB. The Profibus
address is set by rotary switches accessible via holes in the connector side of the SBPC-21-PB.
Figure 3-2: SBPC-21-PB Network Connection With Multiple CDP-01’s
Software Configuration
Configurations have been created to match the single CDP-01 network shown in Figure 3-1. Since the
CDP-01 can have one, two, or three drives, a configuration has been created to match the parameters
present in each drive configuration. This prevents inefficient use of Profibus bandwidth for data that is
inapplicable. The three configurations are:
