无

None.

改变DNB(SDN)模块的节点号,因为你所设置的

DNB(SDN)模块的节点号在设备网中已经存在

available one. The node address you selected is

already in use on that channel.

重新配置DNB(SDN)的扫描列表,删除所有的非

法数据

Reconfigure the scan list table and remove any

illegal data.

检查从站设备和确认连接是否正确

Inspect the field devices and verify connections.

在扫描列表中出现错误的设备处输入正确的设

备ID (厂商,产品号和产品类型)

Enter a matching scan list device sure

that the device at the flashing node address

matches the desired key parameters (vendor,

product code, product type).

修改设置到有效的数据位置

Modify your configuration and check for invalid

data.

确定扫描列表正确。检查网络连接。

Verify scanlist is correctly configured to scan

slave DeviceNet network

connections.

有其它在线激活设备,初始信息，但没有本模块

信息。

are other active devices on the

network,initiating messages,but none of the

messages are for the module.

重新配置DNB(SDN)模块或从站设备

Either reconfigure the slave device,or change the

module’s scanlist to match the slave device.

检查在扫描列表中存在的设备工作是否正常

将该设备添加到设备网中,或者在扫描列表中

删除该设备

Add the device to the network, or delete the scan

list entry for that device.

确保你的DNB(SDN)已经正确的连接到设备网

上,检查网络电缆,检查通讯波特率

Make sure that your module is connected to a

valid network. Check for disconnected cables.

Verify baud rate.

使控制器在运行模式

Put the controller into RUN mode and enable the

RUN bit in the Module Command Array.

检查在模块命令数组中的错误值。

Check the FAULT value in the Module Command

Array.

检查DNB(SDN)的扫描列表确保设备的输入和输

出数据的大小是正确的.检查设备的配置.

Check scan list table entry for slave device to

make sure that input and output data lengths are

correct. Check slave device configuration.

检查DNB(SDN)扫描列表，检查从设备的配置,

重启从站设备

Check accuracy of scan list table entry. Check

slave device slave device

Module is in IDLE mode.

扫描模块已经停止收发I/O数据。

The Scanner has stopped producing and consuming I/O

condition does not affect the scanner’s system or

messaging modes.

设备的返回信息有部分错误发生

Error detected in sequence of fragmented I/O messages from

device (node number alternately flashes).

Device is producing idle state data while the scanner is in Run

Mode.

Available for allocation. Scanner has not yet been detected by

allocated master, or slave mode is enabled but scanner is not

allocated to a master.

不是故障，请重新给DNB(SDN)模块上电或者复位。

This is not an error. At power-up and reset, the module displays

all 14 segments of the node address and status display LEDs.

从站对扫描模块的初始数据响应错误，或扫描模块的配置表

对某一从站是非法的。

Slave device responded with an error to the initialization data

sent to it by the scanner; or the configuration table in the

scanner’s flash memory is not valid for a slave node.

用户在软件中禁止了DNB(SDN)

User has disabled communication port

无.当模块正确启动后此代码自动清除

None. This code clears itself once module

attempts to initialize all slave devices on the

channel.

检查设备的初始化程序和配置,给从站设备配

置一个小点的数据尺寸。

Check slave device installation and

ure the slave device for a

smaller data size.

检查设备的配置或从站设备的当前状态

Monitor scanner to determine if error code clears

when master detects scanner. If error remains,

check scanner slave mode configuration.

无

None.

重新下载adr.

Try the ADR download again. If it still fails, try

clearing the ADR flash by downloading an empty

ADR configuration to the scanner and then try the

ADR configuration again.

重新配置模块。检查程序中的DNB(SDN)命令寄

存器中的禁止位是否为1

Reconfigure your module. Check the disable bit in

the Module Command Register.

检查设备网线的连接和所有设备是否连接正

确。检查出现错误的设备或其它引起故障的设

备和接口

Check DeviceNet connections and physical media

integrity. Check system for failed slave devices or

other possible sources of network interference.

给设备网线提供24V电源。确保已将24V工作

电源正确的传输到DNB(SDN)的通讯端口上
