代码 描述

正常显示,所显示的数字均是DNB(SDN)模

块的节点号

0 - 63 Normal operation. The numeric display

indicates the 1747-SDN’s node address on the

DeviceNet network.

改变DNB(SDN)模块的节点号,因为你所设置的

DNB(SDN)模块无法通过自检

check.

在DNB(SDN)的扫描列表中存在非法的数

71

据(错误设备的节点号码交替闪烁)

Illegal data in scan list table (node number

alternately flashes).

设备网设备停止通讯设备的节点号码交替

72

闪烁()

Slave device stopped communicating (node

number alternately flashes).

在扫描列表中出现错误的设备处输入正确的设

DNB(SDN)扫描列表中的设备ID与实际设

73

备ID不匹配(设备的节点号码交替闪烁)

Device key parameters do not match scan list

table entry (node number alternately flashes).

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).

74

通讯数据过多

Data overrun on port detected.

在DNB(SDN)中没有扫描列表

No scan list is active in the module.

没有直接的网络数据交换

No direct network traffic for module detected.

设备返回到DNB(SDN)中的数据与

DNB(SDN)扫描列表中的数据预留空间不

77

匹配(设备的节点号码交替闪烁)

Data size returned does not match scan lists

entry (node number alternately flashes).

DNB(SDN)无法找到在扫描列表中设置好

78

的设备(设备的节点号码交替闪烁)

Slave device in scan list table does not exist

(node number alternately flashes).

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

重新配置DNB(SDN)模块

Reconfigure your module and change the

addressing.

修改设置到有效的数据位置

Modify your configuration and check for invalid

data.

配置新的扫描列表

Enter a scan list.

无,DNB(SDN)正在监听网络通讯

None. The module hears other network

communication.

检查设备和连接是否正确

Inspect the field devices and verify connections.

DNB(SDN)模块的节点号在设备网中已经存在

Change the module channel address to another

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.

无

None.

建议

75

76

list entry for that device.

确保你的DNB(SDN)已经正确的连接到设备网

79

DNB(SDN)无法向设备网发送消息

Module has failed to transmit a message.

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.

80

81

模块没有激活

Module is in IDLE mode.

模块故障

Module is in FAULT mode.

设备的返回信息有部分错误发生

82

Error detected in sequence of fragmented I/O

messages from device (node number

alternately flashes).

DNB(SDN)和设备通讯时设备有错误的信

息返回

83 Slave device is returning error responses

when module attempts to communicate with it

(node number alternately flashes).

无

84

DNB(SDN)正在初始化

Module is initializing the DeviceNet channel.

运行中设备返回数据的大小和预期值不同

85 Run time data size returned from slave device

is not the size expected.

DNB(SDN)在运行模式时设备挂起

86 Device is producing idle state data while the

scanner is in Run Mode.

Available for allocation. Scanner has not yet

87

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。

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

module displays all 14 segments of the node

address and status display LEDs.

Auto Device Replacement (ADR) error. Slave

device responded with an error to the

89

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.

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.

无

None.

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

Check slave device installation and configuration.

检查设备的配置或设备的当前状态

Check device configuration/slave node status.

Monitor scanner to determine if error code clears

when master detects scanner. If error remains,

check scanner slave mode configuration.

检查DNB(SDN)扫描列表，检查从设备的配置

Check accuracy of scan list table entry. Check

slave device configuration.

无

None.

无

None.

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.
