WARNING!

1. GENERAL

Instead of sending and receiving information to and from frequency converters through I/O, you can connect them to a fieldbus.

Vacon NX frequency converters can be connected to the DeviceNet using a fieldbus board. The converter can then be controlled, monitored and programmed from the Host system.

If you purchase your DeviceNet Option Board separately, please note that the it shall be installed in slot E on the control board of the frequency converter.

Internal components and circuit boards are at high potential when the frequency converter is connected to the power source. This voltage is extremely dangerous and may cause death or severe injury if you come into contact with it.

3. DEVICENET

3.1 Introduction

DeviceNet is an open network based on CAN that is designed to connect low cost industrial control devices (such as limit switches, photoelectric sensors, motor starters, process sensors, frequency converters, panel displays and operator interfaces) to a network and eliminate expensive hardwiring. The direct connectivity provides improved communication between devices as well as important device-level diagnostics not easily accessible or available through hardwired I/O interfaces. The DeviceNet Model is application independent; it provides the communication services needed by various types of applications. Many of today’s lower level industrial control devices must retain their low cost/low resource characteristics even when directly connected to a network. DeviceNet takes this into consideration by defining a specific instance of the Model for communications typically seen in a Master/Slave application. This is referred to as the Predefined Master/Slave Connection Set. DeviceNet allows the interchangeability of simple devices while making interconnectivity for more complex devices possible. In addition to reading the state of discrete devices, DeviceNet provides the capability to report temperatures, to read the load current in a motor starter, to change the deceleration rate of drives, or to count the number of packages that have passed on a conveyor in the previous hour.

3.2 DeviceNet physical layer and media

The basic trunkline-dropline topology provides separate twisted pair busses for both signal and power distribution. Thick or thin cable can be used for either trunklines or droplines. End-to-end network distance varies with data rate and cable size.

and

Devices can be powered directly from the bus cable.

Nodes can be removed or inserted from the network without powering down the network.

communicate with each other using the same

Power taps can be added at any point in the network which makes redundant power supplies possible. The trunkline current rating is 8 amps. An opto-isolated design option allows externally powered devices (e.g. AC drives starters and solenoid valves) to share the same bus cable. Other CAN-based networks allow only a single power supply (if at all) for the entire network.

4.2 LED indications

The DeviceNet Option Board includes three LED status indicators next to the connector: Network status (N), Node address (A) and Module status (M). Network status provides information on the network connection status, Node address blinks the MAC ID of the unit while it is powered and Module status provides information on the DeviceNet module.

A LED test is performed at power-up. The following sequence is performed:

1. All LEDs off

READ FIRST CHAPTER 8 'COMMISSIONING' IN VACON NX USER'S MANUAL (Document nr. ud00701, please visit Vacon’s internet site.

Note! You must select Fieldbus as the active control place, if you wish to control the frequency converter through fieldbus. See Vacon NX User’s Manual.

The recommended method for setting the DeviceNet parameters is with a

(see chapter 6.1). However, the parameters can also be set with the

Tool

DeviceNet Configuration

control keypad

(see chapter

6.2), but then it must be ensured that the parameter settings correspond to the settings in the Master system.

6.1 DeviceNet Configuration Tool

Before using the OPTC7 option board, you must configure the device baud rate and node address to the desired values. This can be done by using a DeviceNet Configuration tool (e.g. Netview or RSNetworx for DeviceNet). The default baud rate is 125 Kbaud and node address 63. All devices must have the same baud rate.

Since all new devices are factory set to node address 63, it is recommended that the address is changed. You must also check or set the following attributes before use:
