ControlNet X30 Description
The FieldServer ControlNet X30 driver can be used to emulate a single slave station on a
ControlNet network. ControlNet scanners can open a connection of up to 450 Bytes in each
direction to the FieldServer. Data transfers are via Scheduled Communication and therefore the
FieldServer has to be scheduled on the ControlNet network using a Network Configuration Tool
such as RSNetWorx or RSLogix. The minimum supported network update time (NUT) is 5 ms.
Connection to the ControlNet network is via two standard BNC connector ports. The connection
may be to either one or both of the ControlNet ports. A connection to both ports provides dual
redundant operation. A Network Access Port (NAP) is also provided for the temporary
connection of a Network Configuration Tool.

Configuring the FieldServer as a ControlNet Server
For a detailed discussion on FieldServer configuration, please refer to the FieldServer
Configuration Manual. The information that follows describes how to expand upon the factory
defaults provided in the configuration files included with the FieldServer (See “.csv” files on the
driver CD).
This section documents and describes the parameters necessary for configuring the FieldServer
to communicate with a ControlNet Client/Scanner.
The configuration file tells the FieldServer about its interfaces, and the routing of data required.
In order to enable the FieldServer for ControlNet communications, the driver independent
FieldServer buffers need to be declared in the “Data Arrays” section, the FieldServer virtual
node(s) needs to be declared in the “Server Side Nodes” section, and the data to be provided to
the clients needs to be mapped in the “Server Side Map Descriptors” section. Details on how to
do this can be found below.
Note that in the tables, * indicates an optional parameter, with the bold legal value being the
default.

The ControlNet MAC ID can also be set via the two rotary switches on the side of the

Alternatively
the
System_Station_Address parameter should be eliminated from the configuration file.
Failing to do so, will cause a warning LED to flash although the MAC ID from the
configuration file will still be used.

Appendix A.2. Using RSNetWorx Version 1.06 with PLC-5 scanner
The Anybus ControlNet module is not supported for versions earlier than 1.06.
•
•
Ensure all nodes are physically connected and start RSNetworx.
Go online (check the Go online box) - all connected nodes should appear on the
screen.
•
•
•
Right click on the PLC5 node and choose ControlNet configuration. The program now
launches the Map Editing Tool used to set up data mapping in the PLC-5 processor.
Right click on the line that contains the Anybus ControlNet module (in the current
version of RSNetworx displayed as Any-BusDT) and choose Insert device connection.
When the line changes to blue, the connection size in, connection size out and to which
address in the PLC the data shall be mapped should be entered. The data is mapped to
the Integer area (N-area). For example, 50 bytes in each direction can be mapped so
now 25 words in and 25 words out can be chosen.
•
Save the configuration, switch the PLC key to run and the data is transferred to/from the
PLC data table at the specified address.
Appendix A.3. Using RSLogix 5000 for network configuration
RSLogix is a programming and configuration tool from Rockwell automation. The information
included in this section is based on an entry in the Rockwell Automation Support Library and
can be accessed at:
www5.software.rockwell.com/support/knowbase.nsf/9dc47c2a86607f2d86256365001169f5/
bb01b77898478eca852568ef005e0b52?OpenDocument
RSLogix 5000 Version 2.25 and higher versions have a generic profile called
CONTROLNET- MODULE which is applicable to devices that connect directly to ControlNet,
such as the 1203-CN1 communications card with a Rockwell drive or a Schneider
Momentum I/O device. The Anybus ControlNet card also uses this profile. All Anybus
ControlNet-enabled I/O will use the same assembly instance numbers, but the data size will
change depending on the application and must be relayed to the end user. The ControlNet
module does not use configuration data so the length should be left at zero, though you
must enter a non-zero number for the assembly instance. The following list provides

Varies with how the module is intialized
Note: The ControlNet module uses a ControlNet 32-bit run/idle header, so the actual data
from the module will always start with word 2 (the third word) of the data. The first 2 words,
at 16 bits each, are the ControlNet run/idle header. If you want to mask off the run/idle
header for clarity, create a user defined type with 2 members - HEADER, type DINT; and
DATA, type INT with ‘input assembly size - 2’. Copy the data from the actual input tag to a
tag of this structure, and then you can reference the structure's DATA member using the
element numbers in your documentation.
Output Assembly Instance:

Size:
Varies with how the module is initialized
Configuration Assembly Instance:

Note: There will always be a configuration tag of type AB:ControlNet_MODULE:C:0 created
for this module, which has one member called Data, of type SINT[400]. This SINT[400] tag
is created regardless of the configuration size, which can range from 0 to 400 bytes (SINTs).
Since a data size of zero is specified, no data will be sent to the module.

Appendix B. Driver Notes

Appendix B.1. Setting the FieldServer’s ControlNet MAC ID
The MAC ID can be set in the FieldServer’s CSV file using the System_Station_Address,
(refer to Section 4.1), or it can be set with the two rotary switches as indicated on the
connection diagram. The left switch selects the left decimal digit and the right switch the
right decimal digit of the MAC ID.
Note that the software setting with the System_Station_Address overrides the hardware
setting with the rotary switches. Set the rotary switches to zero or to the same value as in
the System_Station_Address to prevent the warning LED from flashing. A mismatch will still
result in the software setting being used.
Appendix B.2. Using the Network Access Port
The Network Access Port (NAP) should only be used temporarily to connect a network
configuration tool. It must not be used to connect to the main ControlNet network.
