SFIDK.PS.023.C2.02
DeviceNet is a distributed control network. The DeviceNet protocol is embedded in the add-on
module (AOM) and is a communication protocol conforming to the Open DeviceNet Vendor
Association (ODVA) standard.
The add-on module allows DeviceNet compatible controllers, sensors and network management
tools to control, monitor and supervise the MAG 6000/MASS 6000 flowmeter. The add-on module
is designed to the DeviceNet system “Protocol for Vendors” as a slave device.
1.4 Product and
environment
The MAG 6000/MASS 6000 flowmeter functions as a slave on the DeviceNet network. All
addressing and linking the nodes is done at installation time by a network manager tool. The
network installer and the network management master have significant influence on how the
nodes function on the network. A DeviceNet network can support up to 64 nodes.
1.5 Network
The end-user is a network manager programmer or controller who sees the DeviceNet add-on
module as an invisble bridge to the flowmeter. Control and supervision of the flowmeter will be
possible through the standard parameter set.
1.6 User profile
The interface connection to the DeviceNet network is implemented through a microprocessor
with an imbedded CAN controller. For the MAG 6000, two different I/O assemblies are available
in the AOM. For the MASS 6000 seven different I/O assemblies are available in the AOM.
The I/O assembly can be controlled by the user. The I/O assembly can only handle polled mode.
For explicit messages the interface uses the pre-configured master functionality.
1.7 Interface to DeviceNet network
This manual is intended to be used both as an instructional and a reference manual. It only
briefly touches on the basics of the DeviceNet protocol.
The manual is also intended to serve as a guideline when you specify and optimize your
communication system.
Even if you are an experienced DeviceNet programmer, we suggest that you read this manual
entirely before you start programming, since important information can be found in all chapters.
1. Introduction to
DeviceNet
1.1 About this manual
This manual assumes that you use a Siemens Flow Instruments MAG 6000 or MASS 6000 unit
with DeviceNet. It also assumes that you are using a PLC or PC, as a master, that is equipped
with a serial communication option supporting all the DeviceNet communication services
required by your application. Furthermore, it is assumed that all requirements stipulated in the
DeviceNet standard as well as those set up in the generic profile and those pertaining to the
MAG 6000 or MASS 6000 flowmeters are strickly observed as well as all limitations mentioned
fully respected.
The Siemens Flow Instruments DeviceNet module is designed to communicate with any master
abiding by the DeviceNet standard. It is therefore assumed that you have full knowledge of the
PC or PLC you intend to use as a master in your system. Any questions pertaining to hardware
or software produced by any other manufacturer is beyond the scope of this manual and is of no
concern to Siemens Flow Instruments.
If you have questions about how to set up master, master communication or communication to
a non Siemens Flow Instruments slave, the appropriate manuals should be consulted.

3. Installation
3.1 Add-on module
19” rack mounted versions IP 67 compact versions
The installation procedure for an add-on module to a Siemens Flow Instruments USM II
transmitter is as follows:
1. Unpack the add-on module and
insert it in the bottom of the signal
converter as shown.
2. Press the add-on module in the
direction shown, until it stops and
is firmly seated in position
3. This completes the add-on module installation, and the signal
converter may now be connected
to the terminal box. Communication with the display/keypad and
the electrical input/output terminals is established automatically
when the power is applied.
After mounting, the DeviceNet menus are shown in the display and (set table) values are stored
in the SENSORPROM

3.6 EMC precautions
The following EMC precautions are recommended to obtain an interference free operation of
the Devicenet network. Additional information on EMC can be found in the MAG 6000/MASS
6000 handbooks.
Note
Relevant national and local regulations, for example regarding protective earth connection,
must be observed.
The DeviceNet communication cable must be kept away from cables that can contain electrical
noise such as motor and mains cables to avoid coupling of noise from one cable to the other.
Normally a distance of 200 mm (8 inches) is sufficient, but it is generally recommended to keep
the longest possible distance between the cables, especially where cables are running in
parrallel over long distances.
The use of separate cable trays for signal cables and high power cables has proven to be a very
good practice for eliminating noise coupling.
If the DeviceNet has to cross a main cable or other cables that are a source of noise, they must
cross eachother at an angle of 90°.
PE
Termination: Connecting a resistor of 121Ohm 0.25W over 91,92 will terminate the
DeviceNet Bus. This must be done if the device is the last on the Bus.
