FIELDBUS INTERFACE

DeviceNet protocol

To enable the DeviceNet physical interface, ensure that switches 1 and 2 of the DIP switch communications card (on the CPU module) are on. The external connections through the fieldbus interface are as follows.

Table 13: Fieldbus interface external connections (DeviceNet)

Path	Connection (external)	Wire color

V–	Pin 3, CAN_GND	Black
L	Pin 2, CAN_L	Blue

C	Pin 5, CAN_SHLD	Bare

H	Pin 7, CAN_H	White

V+	Pin 9, CAN_V	Red

The Modbus status (MS) and network status (NS) LEDs indicate the status of the Fieldbus interface.

Table 14: DeviceNet LED indications

LED	LED operation	Description

MS	Green on, red on, green on	Device self-test

	Flashing green	Device in standby state

	Green on	Device operational

	Flashing red	Recoverable fault

	Red on	Unrecoverable fault

NS	Flashing green	Online, not connected

	Green on	Online, connected

	Flashing red	Connection timeout

	Red on	Critical link failure

	Red and green	Network access detected

When used for DeviceNet, the fieldbus port has the following characteristics.

•Baud rate: 125, 250, and 500 kbps

•MAC ID: 0 to 63

•Vendor ID: 928

•Product Code: 0x4D39

•Message types: poll, and explicit messaging

DeviceNet Communications

The device profile is an extension of the Communications Adapter Device Profile (0xC0). It is a group 2 only server. The MAC ID and baud rate are programmable through the EnerVista MM300 Setup software and the Graphical Control Panel. The MM300 supports the following DeviceNet object classes.

CLASS	OBJECT

01H	Identify

02H	Message Router

03H	DeviceNet

05H	Connection

A0H	Generic Data - Polling/Explicit

B1H	Explicit Control Writes

B0H	Analog Data - Explicit
