Configure RevPi Gate for DeviceNet

Setting MAC-ID and Bitrate

The MAC-ID and bitrate are assigned in binary format.

You can set the MAC ID via the DIP switches 1-32, and via switches S1 and S2 you can set the bitrate.

Set an address switch to “OFF” to switch bit value 0 or to “ON” to switch bit value 1.

Valid value range for the bitrate:

Valid value range for the MAC-ID: 0-63

Switch Setting Value
Switch 1: ON,
Switch 2: OFF
125 kbit/s
Switch 1: OFF,
Switch 2: ON
250 kbit/s
Switch 1: OFF,
Switch 2: ON
500 kbit/s
Switch 1: ON,
Switch 2: ON
Automatic bit rate detection

Example: Here, you can see the switch setting for the MAC address 42 and the bitrate 500 kBit/s.

DeviceNet Objects

To configure the gateway component, you have to make the appropriate settings in the DeviceNet objects with the configuration software of your Device master.

Object structure

DeviceNetTM uses the application layer CIPTM (Common Industrial Protocol) that was specified by the ODVA (Open DeviceNet Vendor Association – http://www.odva.org). Physically based DeviceNet on CAN (Controller Area Network).

CIP is a connection oriented protocol. It allows the exchange of I/O data via cyclical I/O messages and the exchange of general data for configuration, diagnosis and Management via explicit messages. For this purpose, CIP defines 4 essential functions:

  • Uniform object model for addressing data
  • Uniform communication model for exchanging data
  • Uniform configuration methods
  • Uniform device profiles

Each DeviceNet device is characterized by a collection of objects. Each object has a defined behavior. Each object belongs to a class. Objects belonging to the same class are called instances of this class. Data elements within an object are called attributes. All attributes can be addressed with class, instance and attribute IDs. Services are explicit tasks that an object can execute.

The following sections describe which objects, attributes and services are supported by the gateway component.
Class Code 0x01Hex

This class contains information about the identification of the module.

The gateway component supports the following functions in this class:

Get Attribute Single (0x0e): 
This function returns the content of certain attributes.
Reset Service (0x05):

  • Type 0: The module restarts the DeviceNet Software.
  • Type 1: The module is reset to the original settings.
