1 GENERAL PRODUCT INFORMATION
1.1
INTRODUCTION
1)
This manual will explain how to communicate with a Bronkhorst
instrument to your PC/PLC using RS232 serial communication. You
have to write software yourself using the information of this
document in order to be able to operate these instruments.
Bronkhorst also offers software to easily operate digital instruments
with your PC using Microsoft Windows. On the highest supported
communication level, you may use FlowDDE channels for Windows
application-programs with this facility. You can use the program
FlowDDE for easy connection between Windows applications (e.g.
Excel, Visual Basic, LabVIEW, Delphi, Borland C) and digital
instruments. There are several examples available for LabVIEW, Visual
Basic and Excel environments.
On a lower communication level, you can also use the FLOWB32.DLL for reading/changing parameter values.
To read and write parameter values from or to FLOW-BUS devices directly through the available interfaces there is a
special protocol for messages between these devices. This protocol has been specially developed for Bronkhorst
equipment so no third party equipment can be connected. It consists of a hierarchical setup for instruments / nodes
(max. 126) containing processes (max. 127) with parameters (FBnr) (max. 32) which values can be set to certain values
to enable settings/properties for the instruments.
When operating a FLOW-BUS system with a HOST computer, you need to know this message protocol if you choose to
drive the interfaces directly. When you use a RS232/FLOW-BUS interface (without the micro-switch and 2 LED’s), you
first have to initialise the interface. This can be done by means of sending some ASCII-strings to the interface through
RS232. See chapter “Initialising RS232/FLOW-BUS interface” for more details.
When you communicate directly via RS232 on a Multibus instrument or when you use a new type of RS232/FLOW-BUS
(baud rates up to 38K4 with switch and 2 LED’s) interface, no special initialisation is needed.

This includes Bronkhorst High-Tech B.V. , Bronkhorst Cori-Tech B.V. and
M+W Instruments GmbH.
1.2 MULTIBUS TYPES
In 2000 Bronkhorst developed their first digital instruments according to the “multibus” principle. The basic pc-board
on the instrument contained all of the general functions needed for measurement and control, including alarm,
totalizing and diagnostic functions. It had analog I/O-signals and also an RS232 connection as a standard feature. In
®
addition to this there is the possibility of integrating an interface board with DeviceNet™, Profibus-DP , Modbus ,
FLOW-BUS or EtherCAT protocol. The first generation (MBC-I) was based on a 16 bit
Fujitsu controller. It was superseded in 2003 by the Multibus type 2 (MBC-II). This
version was also based on the 16 bit Fujitsu controller but it had several
improvements to the MBC-I. One of them is the current steering of the valve. It
reduced heat production and improved control characteristics. The latest version
Multibus controller type 3 (MBC3) is introduced in 2011. It is build around a 72MHz
32 bit NXP ARM controller. It has AD and DA controllers on board which makes it
possible to measure noise free and control valves without delays. The internal
control loop runs 6 times faster compared to the MBC-II therefore control stability
has improved significantly. It also has several improved functions like reverse
voltage protection, inrush current limitation and overvoltage protection.
MBC3 instruments can be recognised by the “MBC3” placed on lower left side
of the instrument label (see example).

Start sending
Make sure your PC or PLC is connected to the RS232 interface by means of
the correct cable.
• Multibus instruments need a special cable with T-connector.
• RS232/FLOW-BUS interfaces need a one-on-one 9-pole cable
without crossings with male and female connector
Cable lengths for RS232 must not exceed 10 meters.
Make sure instrument or interface is powered (+15…24Vdc)
In case of RS232/FLOW-BUS interface without micro-switch and LED’s, first
see that interface gets a free address on the FLOW-BUS. Follow initialisation
procedure described at [Initialising RS232/FLOW-BUS interface]
Use settings [38400,n ,8 ,1 ] for your COM-port:
Baud rate = 38K4 Baud, no parity, 8 data bits, 1 stop bit.
Start sending messages as described in following paragraphs.

2 INTERFACES
2.1
RS232/FLOW-BUS INTERFACE
The RS232/FLOW-BUS interface is an interface between the FLOW-BUS and the RS232 V24 serial (computer) port. It
will either be supplied as a separate enclosed unit with a FLOW-BUS connector and a RS232 connector or as an
integral 14TE module of your E-7000 readout and control system. The converter offers communication with a baud
rate up to 38400 baud. Communication software support is available. Communication settings are: 38400, n, 8, 1.

RS232 ON MULTIBUS INSTRUMENT
The RS232 interface on a Multibus instrument can be connected to any RS232 V24 serial (computer) port. Make sure
to respect the hook-up diagram. Bronkhorst offers special cables for communication, separating the RS232 lines from
the power and analog in- and output. On the 9-pin male D-sub connector of the instrument RX and TX are available on
pin 6 and pin 1.
RS232 communication is possible by:
• 9-pin Sub D-connector
(non IP65 applications, e.g. EL-FLOW)
• 8 DIN connector
(IP65 applications, e.g. CORI-FLOW)
For the exact connections please advise your hook-up diagram.
2.2.1
Applications, e.g. EL-FLOW
By default, the interface offers communication at a baud rate of 38400 baud. On instruments that offer
the possibility to change the RS232 baud rate, the baud rate may be configured differently. See the
technical documentation of your instrument which baud rates are supported.

2.2.2
Facilities
No handshaking facilities are used. On the side of the PC/PLC a nul-modem connector is needed.
Communication settings are: 38400,n,8,1.
Bronkhorst offers a special cable needed for communication.
Communication software support is available.

The Multibus RS232 interface is a serial interface between the Multibus instrument and the RS232 serial (computer)
port using the FLOW-BUS protocol for communication. This means that for serial RS232 communication a Multibus
instrument with RS232 can be treated as a FLOW-BUS system with one instrument and a FLOW-BUS/RS232 interface.
All available software already existing for FLOW-BUS RS232 communication can be used for Multibus instruments also.
Only initialisation is different. Use of FlowDDE32 is only possible from V4.23 and higher.

3 FLOW-BUS PROTOCOL DESCRIPTION
3.1
GENERAL
On the highest supported communication level, you may use DDE-channels for Windows application-programs with
this facility. On a lower communication level, you can use the FLOWB32.DLL, for changing parameter values.
To read and write parameter values from or to FLOW-BUS devices directly through the available interfaces there is a
special protocol for messages between these devices. When operating a FLOW-BUS system with a HOST computer,
you need to know this message protocol if you choose to drive the interfaces directly.
When you use a type of RS232/FLOW-BUS interface (baud rate up to 38K4) you may first have to initialise the
interface. This can be done by means of sending some ASCII-strings to the interface through RS232.
See also paragraph “Initialising RS232/FLOW-BUS interface”
There are two different communication protocols for the PC and the RS232 HOST:
•
an ASCII protocol for communication that is compatible with existing FLOW-BUS applications.
This protocol serves only one master/slave dialog at a time.
•
an enhanced binary protocol that supports concurrent sending of messages to different nodes. This protocol
contains a message-sequence number and serves more than one master/slave dialogs at a time.
The RS232-HOST module automatically recognises the protocol used by the PC and adapts its behaviour to the
protocol in use. The type of protocol is determined by the first character of a message.
•
•
The first character is ‘:’
The first character is DLE
(0x3A) existing type of message.
(0x10) enhanced type of message.
Via the FLOW-BUS DLL (FLOWB32.DLL) the PC determines which protocol is in use.
The communication relation is always master (PC) and slave (HOST). The HOST will always respond on a request from
the PC.
3.2
INITIALISATION OF LOCAL HOST INTERFACES ON MULTIBUS INSTRUMENTS
When you use a digital instrument with RS232 interface, baud rate is fixed on 38K4 baud and no special initialisation is
needed. Through the serial line connected to a COM-port of your computer or to a PLC you have to communicate with
the instrument using the FLOW-BUS protocol. Each instrument has its own node address (3...120). If you want to send
a message to the instrument you have to know this node address. However, if you send a message to node address
128 the instrument will always respond to your message. On a point-to-point connection like RS232 it is the easiest
way to make the communication work under all circumstances (it is independent of the real node address of the
instrument).

INTERFACE STRUCTURE
3.3.1
Basic datalink format
The basic data link message format has the following fields:
node
message destination
length
data field length
data
data
Data
etc.
In the FLOW-BUS environment the data field may contain up to 256 bytes of data. In the HOST application described
here, the messages are according to PROPAR coding rules and the data field will contain a maximum of 64 bytes.
3.3.2
ASCII table
The American Standard Code for Information Interchange (ASCII) is a character-encoding scheme based on the
ordering of the English alphabet. ASCII codes represent text in computers, communications equipment, and other
devices that use text. Most modern character-encoding schemes are based on ASCII.

3.3.3
RS232 ASCII protocol
An ASCII protocol is used on the existing RS232-HOST. To be compatible with existing driver software the ASCII
protocol is available.
A basic data link message is coded in ASCII as follows:
:
Byte
:
Len1, len2
node1, node2
data1, data2
CR
length
len1
len2
node
node1 node2
data
data1
data2
CR
Explanation
Initial character (semicolon)
Length of message including the node address in bytes, so (len1, len2) is
the basic message length +1.
node address of destination (PC to HOST)
node address of source (HOST to PC)
message field
termination character
All bytes (except the initial and termination character) are converted from 1 binary byte to 2 hexadecimal bytes in
ASCII representation.
Example: binary data byte 0x2A --> hexadecimal ASCII characters 0x32, 0x41.
A special message type is used to pass error messages from the HOST to the PC. Its structure is as follows:
:

Enhanced binary protocol
The enhanced protocol is binary coded. Control sequences are used to recognise the beginning and end of a message
in a byte stream. A control sequence starts with a DLE byte (0x10) and is followed by a control byte. The following
control sequences are defined:
First byte
DLE (0x10)
DLE (0x10)
DLE (0x10)
DLE (0x10)
Second byte
STX (0x02)
ETX (0x03)
DLE (0x10)
any other
character
Function
Start of message
End of message
Data byte 0x10
Not allowed. Messages that contain such a sequence will be
ignored. The receiver waits until a new DLE STX sequence.
The [DLE DLE] sequence is used to prevent possible DLE bytes in the transmitted binary data stream from being
recognised as the start of a control sequence. The sender replaces any DLE bytes in the data by two DLE bytes. The
data link of the receiver will convert a [DLE DLE] sequences to one DLE byte.
If a RS232 error (receiver overrun, framing error, not allowed control sequence) occurs, the data link
frame is ignored.
The enhanced binary coded messages between PC and HOST are structured as follows:
DLE
Byte
DLE, STX
seq
node
len

DLE, ETX
STX

len

ETX
Explanation
start sequence
message sequence number
node address of destination (PC to HOST)
node address of source (HOST to PC)
length of data field in bytes
message field
end sequence
The enhanced protocol allows the transmission of more than one request at a time. The sequence number makes it
possible to associate the answer to the according request. The HOST has more than one message buffer where
messages may be stored (typical 5). When the message buffers are full, the HOST responds with an error message.
The responses from the HOST to the PC have the same message format as the request. An error message has a special
format:
DLE
STX
seq

0x00

COMMUNICATION MESSAGES
Communication messages between FLOW-BUS interfaces and other devices consist of command strings with specific
information. This command string is either ASCII (RS232) or BINARY. Basically the string contains several information
bytes. Through RS232 these hexadecimal bytes are converted in ASCII (e.g.: byte value 0x0A is "0A" in ASCII and capital
letters should be used). Messages via RS232 are preceded by the “:” character and terminated with "\r\n" (Carriage
return-Line-feed).
There are several COMMANDS available in the FLOW-BUS messages. Only command RD (04) and WR (01) are required
for all the standard parameter reading and writing. A RD command will be answered with a WR command, containing
the value asked for or a status message, containing an error number. A WR command will be answered with a status
message, containing an error number (if error number = 0, than WR command was OK).
ASCII character : has hexadecimal value: 3A
ASCII character ‘ \r ’ has hexadecimal value: 0D
ASCII character ‘ \n ’ has hexadecimal value: 0A

CHAINING
Chaining can be used to send or request more than one parameter per message. When the parameters are all
members of the same process, they can be chained at parameter level. When the parameters are members of
different processes, they can be chained at process level. A combination is also possible. For chaining at parameter
level the first bit of the parameter number should be set if there is following another parameter at the same process.
For chaining at process level the first bit of the process number should be set if there is another process following.

INITIALISING RS232/FLOW-BUS INTERFACE
If you use a RS232/FLOW-BUS interface for communication (without the micro-switch and 2 LED’s), note that this
module is not part of the (FLOW-BUS) token-ring network, directly at power-up. This means that it is always necessary
to re-initialise the module when power has been interrupted! This is not the case when using an RS232/FLOW-BUS
interface with micro-switch, red LED, green LED and RJ45 connector for FLOW-BUS. By means of the switch you may
force the interface to find a free address on the FLOW-BUS once. You may skip the initialisation and start directly
sending messages.
Also when using digital (Multibus) instruments with RS232 directly on the instrument it is not needed to initialise (give
a free node-address to) the instrument on the FLOW-BUS because instrument is not physically connected to the
FLOW-BUS, but only uses the same protocol. You may start directly sending your messages to the instrument on
either the node-address of the instrument in its memory e.g. node 3 (selective response) or to node-address 128
(always response).
At power-up situation you can communicate with the RS232 interface only at the RS232 side via node 0. To get part of
the FLOW-BUS you have to send an init command, send the network parameters PNA, SNA, NNA, LNA and BM and
send a reset command. From this moment the interface is part of the FLOW-BUS. Ensure the module gets a free and
unique address on the bus, 2 modules on the same address will cause communication problems. When you are sure
that there are no more interfaces in the system, simply force the RS232/FLOW-BUS interface to address 1. This
address is reserved for an interface. PC-support software (FLOWB32.DLL) will search for a free address on which the
interface will be installed.
Follow the steps below to realise correct initialisation for this interface via RS232:

RS232 interface

4 DUAL INTERFACE OPERATION
When operating a controller (reading measured value and sending setpoint) for proper operation it is important that
the controller gets its setpoint from the right source. Setpoints may come from different sources: analog input, field
bus interface or RS232 or may be overruled by close valve or open valve (purge) commands. Therefore it is important
to know what the setpoint source of the controller is. This can be set by means of parameter control mode (process 1,
parameter 4).
In some cases it is possible that the setpoints may come from 2 sources at the same time. The last send setpoint will
be valid and send to the controller. This is the case in control mode = 0, when setpoints may come through any field
bus interface or RS232.
However, there could be situations where control over the instrument seems impossible. This is the case when the
instrument comes into a safe-state e.g. when field bus communication is disturbed or disconnected. Valve will be
forced to a safe state automatically: closed (NC) or fully open (NO).
In case you want to get control back via RS232 operation, you have to change the control mode. When control mode
gets value 18, safe state will be overruled and sending setpoints via RS232 interface will have effect on the controller
again.
See also document nr. 9.17.023 for more detailed description about digital instrument parameters and
their behaviour.

5 PARAMETER INFORMATION
FLOW-BUS is used for parameter value exchange between instruments and operation modules (keyboard or PCinterface). Parameter information consists of several properties for behaviour within the FLOW-BUS system. In the
‘parameter properties’ table you will find a list of parameters and their properties. In the ‘parameter values’ table, the
values are described more detailed. This list consists mostly of parameters for mode settings.

Property description in parameter properties table:
Description
unique parameter number (also used for DDE-communication : P(x))
name of the parameter, used for parameter identification
process where parameter is used on FLOW-BUS module used for communication directly through
RS232 when filled in the table, this value has to be used (for parameters located in only 1 process)
when empty in the table, process has to be determined from the FLOW-BUS system information
(for parameters located in more than one process, e.g. setpoint, measure);
parameter number in process on FLOW-BUS module used for communication directly through
RS232
variable type for information about amount of bytes
• c (unsigned) char type
1 byte value 0..255
• I (unsigned) integer type 2 bytes value 0..65535
• f float type
4 bytes value +-1.18E-38..+-3.39E+38 (IEEE-floating point notation)
• l (unsigned) long type
4 bytes value 0..4294967295
data types > 1 byte are MSB first.
variable length to indicate length of string of chars used in combination with VarType c for
transportation of strings through FLOW-BUS: value 0..65535
VarLength indicates the amount of bytes for a parameter type
• -2 indicates that a string is zero-terminated, not defined for length
• X indicates a string with a length of X bytes (characters)
• 0 means no info required, i.e. zero-terminated.
minimum value of parameter allowed when parameter is read/written via RS232, the value will be
checked on this limit (error when out of limit)
maximum value of parameter allowed when parameter is read/written via RS232, the value will be
checked on this limit (error when out of limit)
indication if parameter is allowed to be read via FLOW-BUS
indication if parameter is allowed to be written via FLOW-BUS
indication if parameter should be polled continuously by RS232 application in order to keep
(changing) parameter information up to date
indication if parameter is for advanced users only these are mainly parameters for
maintenance/service
indication if parameter is secured for use through FLOW-BUS reading this parameter is possible,
but changing it needs special handling
indication if parameter is highly secured (only few parameters) reading this parameter is possible,
but changing it needs special handling
short description about meaning of parameter or what it is used for
parameter DDE string (max. 10 characters), DDE value when parameter is not available on
instrument; also: until FlowDDE V4.58 used for parameter identification
Parameter acceptance:
Changing parameter values is possible when a parameter is not read-only and not secured. The range
and type of parameters are described in the tables. When parameter values are out of range they will
be either 'clipped' on the nearest value allowed or you will get an error message: 'parameter value
error'.

(FlowDDE) Parameter numbers:
All parameter information is referenced to the parameter number. This is a unique number for a parameter to avoid
redundancy. These numbers are needed for DDE communication only.
For communication with FLOW-BUS through other ways than DDE: directly via RS232 ASCII-strings or via C-libraries
(DOS or Windows), use the parameter numbers for the FLOW-BUS modules (in column FBnr of table Parameter
properties). Now you will always have to know the node-address of the instrument on the FLOW-BUS, the process
number on the instrument and the parameter number on the instrument.
Process nr could be read from the table or has to be determined, when nothing is filled in. In most cases process
number will be 1. Node-address should be determined also. This is the node-address of the instrument on the FLOWBUS. Newer RS232 protocols on Multibus instruments accept node = 128. When sending messages to this node
address, the message will be always accepted, unregarding the node address of the instrument on the bus.
It is important to know that not all parameters are available on all FLOW-BUS/Multibus devices.
For more details about parameters and their use see also document nr. 9.17.023 for description of
digital instruments. If you have the program FlowDDE, you can also get an overview of which
parameters are available on which devices.
APPENDIX 1 AND 2 WILL GIVE INFORMATION ABOUT PARAMETERS, THEIR PROPERTIES AND THEIR POSSIBLE
VALUES.

6 TROUBLESHOOTING
6.1
LED INDICATIONS
LED indications can be very useful in case of problems with the instrument.
The green LED is normally used for instrument status indication, like normal operation or special function mode. For
DeviceNet it is also possible to show that the instrument is in abort state and idle state. The red LED is normally used
to for error/warning indication (how longer the flash, how greater the trouble).
More information can be found in the manual “917023 Operational instructions digital instruments”
This document can be found at:

6.2
TROUBLESHOOTING HINTS AND TIPS
SITUATION
Description
RS232 communication problems
Check cables. Make sure correct cables are used for specific purpose.
Check address of interface (slave). Sending messages to node 128 will mostly
be accepted by the interface.
Try to reset the instrument and/or restart your PC/PLC.
Make sure your messages are assembled according to FLOW-BUS protocol
description.
Make sure the parameter values you try to read/write are available and in
the correct ranges (check tables).
Controller doesn’t respond on setpoints:
• Check control mode, when 0 and other field bus gives error: safe state
will be entered, resulting in safe setpoint. Can be overruled by making
control mode = 18 (RS232 only operation)
• Alarm or counter module in instrument forces setpoint to alarm setpoint.
Reset alarm or counter and proceed.
• Setpoint slope could have very high value. New setpoints will be reached
when this slope time has been elapsed. Make setpoint slope smaller.
• Control mode could have other value than 0 or 18. Check function when
value is different.
• If measure doesn’t change check forward pressure and piping (evt. shutoff valves).
• Make sure setpoints are within allowed range: 0...32000 (= 0...100%).
• Make sure setpoints are send to proper instrument and process (mostly =
1) and parameter (FBnr for setpoint = 1), and type of data is correct
(short integer = 2 bytes MSB first)
