Set the DeviceNet MAC ID and Baud Rate

The MAC ID and baud can only be set using the DIP switches on the front of the D77B-DSNAP.
A software tool (such as CH Studio) can view the settings for the D77B-DSNAP MAC ID and
baud rate, but cannot be used to modify them.

Refer to the following instructions, figure and table when setting the MAC ID and baud rate.

● Moving a DIP switch to the right is ON and moving the switch to the left is OFF. The

MAC ID is in binary with the major units numbered to the right of the switch on the side
label. Adding up the major units set to ON determines the MAC ID of the D77B-DSNAP.

Example: To set the MAC ID to 25, start from the top (or 32) and set the switches to OFF, ON,

ON, OFF, OFF, ON (16+8+1=25).

● The baud rate is set using the configuration switches B0 and B1.

Most significant bit to be at top or left end of switch block.

To set the DeviceNet MAC ID and baud rate, set the DIP switches
to the desired settings.
The following example is set to MAC ID=25 and Baud 125K.

“Out of Box” Operation

Note: Before applying power to the D77B-DSNAP for the first time, make sure it is properly

mounted on the starter and that all connections are made (DeviceNet, terminal adapter
and auxiliary connector).

September 2002

When the D77B-DSNAP is properly installed, and has a properly set baud and MAC ID, per the
“Installation” section on Page 11, the following tables in the Quick Start section indicate the
information to expect for I/O assemblies on DeviceNet.

Quick Start

This part of the section provides the information necessary to install and operate the D77B­DSNAP on a Full Voltage Non-reversing (FVNR)
Starter and an S751 Soft Start motor controller. Detailed information is available in Appendix A
for setup of enhanced parameters and extended Input and Output data (assemblies).

Safe State Behavior

The safe state behavior of the D77B-DSNAP is factory set to Fault and Stop. Refer to Page 35,
Table 33 Control Supervisor Object (0x29) Instance 0x01 (16 Dec.) for more information. Safe

State is defined as the state in which the D77B-DSNAP will place the motor controller when a
communication loss is detected. The D77B-DSNAP will be in a safe state when the unit is
powered but does not have a valid I/O connection established.

WARNING

Intelligent Technologies (

IT.

) D77B-DSNAP

If the Safe State value is set to Run1 or Run2, any time the D77B­DSNAP is powered and does not have a valid I/O connection, the
motor controller will be commanded to the Safe State value. This
includes first powering up the DeviceNet system (D77B-DSNAP)
and not having the controller on-line.

Input and Output Assemblies

An I/O assembly is an ordered collection of data that the system controller exchanges with
the D77B-DSNAP for monitoring and control. The input assembly is the data that is sent from
the D77B-DSNAP to the system controller for monitoring of the D77B-DSNAP. The output
assembly is the data that is sent from the system controller to the D77B-DSNAP for control of
the D77B-DSNAP.

The D77B-DSNAP offers a variety of input and output assemblies, as indicated in the following
table. The tables in this part of the section provide data definitions and details on these
assemblies.

distributed throughout the DeviceNet subnet. The subnet is then being controlled by a PC or
PLC, which scans the D77B-DSNAP for control and monitoring information.

Overload

A phase current unbalance trip will occur if one or two of the line currents are 40 –
60% or less of the remaining line(s) for longer than 10 seconds.

A phase loss trip will occur with a load current of at least 75% of the minimum FLA
if one of the two input line voltages is lost, with the line current going to zero for
longer than 10 seconds.

While the motor is running and depending on the FLA and trip class settings, when
the FLA is exceeded for a period of time (depending on the trip class setting), a
thermal overload trip will occur. For more information on this feature, see the

Auxiliary opening on the front of the D77B-DSNAP.

While the motor is running, a warning will be activated when the current falls below
a user-settable % of overload’s FLA pot setting.

While the motor is running, a warning will be activated when the current rises

To protect the SCRs from premature damage, a temperature sensor monitors the

All of the I/O assemblies are viewable and settable from the I/O Info Tab of the Property
Pages. The assembly can be changed by simply selecting on the new assembly and pressing
Apply in the lower right of the page. After the new assembly is chosen, a representation of
the data format and structure for the new I/O assembly is created.

Using a Generic DeviceNet Tool

When configuring the D77B-DSNAP with a DeviceNet management tool other than CH
Studio, refer to the tables in Appendix A: Supported DeviceNet Objects for the definitions of
individual attributes. In addition, an Electronic Data Sheet (EDS) file is available at the Web
site www.cutler-hammer.eaton.com/it for use with tools that can use an EDS file.

Follow these steps to configure a D77B-DSNAP through a generic DeviceNet tool:

1. Search for EDS and download the D77B-DSNAP EDS file from the Cutler-Hammer Web
site:
www.cutler-hammer.eaton.com/it

Note: There are multiple EDS files for the D77B-DSNAP, depending on whether it is used with

an FVR, FVNR or S751 configuration.

2. Open/start the tool.

3. Load the EDS file into the tool.

4. Go on-line and connect to the D77B-DSNAP you wish to configure.

5. Open the EDS for the D77B-DSNAP and edit the attributes. For a full list of attributes and
definitions, see Appendix A: Supported DeviceNet Objects.

) D77B-DSNAP

6. Send the changed attributes to the D77B-DSNAP.

7. Close the tool.

Autoconfiguring the D77B-DSNAP for the Starter

1. Verify the D77B-RJJ1 is installed between J1 on the D77B-DSNAP and J1 on the Starter
Terminal Adapter.

2. Connect the “out-of-box” D77B-DSNAP to a powered DeviceNet network.

3. Apply power to the starter terminal adapter, the MS/NS LED should change from
blinking red to blinking green.

4. If possible verify that the configuration has occurred by reading the device type from the
Identity Object (instance 1 attribute 2)
0x000C — Configuration has not occurred
0x0016 — Starter
0x0017 — S751 Soft Start

Note: It can take as long as 15 seconds for the autoconfiguration to be performed on an S751

and 7 seconds for an

Note: The autoconfiguration is a one-time event. To autoconfigure the D77B-DSNAP for

another motor controller, an out-of-box reset must be performed. Using a DeviceNet
configuration tool, perform a reset to the Identity Object, instance 1 data = 1.
