现场总线

对于BK3150

Fieldbus RUN 指示现场总线通信状态，BF和DIA亮红灯代表通信异常

Fieldbus -RUN	BF	DIA	含义	处理方法
亮	暗	暗	操作状态:RUN, 可以输入可以设置读书。	正常工作
亮	亮	暗 , 闪	1. 总线激活，且从站已经参数化	启动主站
			2. 总线回应PROFIBUS 错误: K-Bus 输出变为 0 或  K-Bus 输出保持	参数检验, 配置
暗	暗	暗	主站数据交换没有开始	运行程序
暗	亮	亮	无总线	主站启动,检查电缆
暗	亮	暗, 闪	由于PROFIBUS通信错误: K-Bus停止通信	主站启动, 参数检验, 配置

对于BC3150

LED RUN	LED BF	LED DIA	含义
灭	灭	灭	没有连接现场总线，耦合器正在搜索合适的波特率
亮	亮	亮	主站未激活
亮	亮	灭	总线耦合器已经找到合适的波特率了，等待配置和参数设置
亮	灭	灭	无错误，耦合器正在交换数据
亮	灭	闪	错误，参考错误代码

对于EL6731

LED	Color	Meaning
PB Err	red	off	DP-Master in CLEAR/OPERATE mode, all DP-Slaves are in Data-Exchange
		blinking	DP-Master in CLEAR/OPERATE mode, at least one DP-Slave in Data-Exchange
		on	DP-Master in STOP mode

 

对于BX3100

LED（BUS）	意义
暗	没有连接，耦合器正在搜索合适的波特率
亮红灯	快闪——错误代码——错误参数
亮橙灯	总线耦合器找到了正确的波特率，等待配置与参数设置
亮绿灯	连接正常，BX控制器正在通信

DIA-LED blink codes

If an error occurs in the parameterisation or configuration during DP start-up, this is indicated both through the fieldbus LEDs and in the diagnostic data.

Fast blinking	Start of the error code
First slow sequence	Error code
Second slow sequence	Error argument (error location)

Error code 1

Error code 1 indicates that a reserved bit in the UserPrmData has been set to an incorrect value, or that the function corresponding to the bit in the UserPrmData is not supported. The error argument describes which UserPrmData byte has been detected as containing an error (the offset of the faulty byte + 1).

Error code 3

Error code 3 indicates that a combination of functions selected in the UserPrmData is not allowed. The error argument describes the impermissible combination.

Error code argument	Description
1	The Reaction to DP error cannot be set to "Outputs unchanged" in synchronous mode
2	The DPV1-MSAC_C1 connection has been activated by the master, but no DPV1-MSAC_C1 connection is defined
6	The Multi-configuration mode is not allowed if Checking the CfgData is switched off
8	Synchronous mode may only be activated when at least one DP output byte is configured
10	The optimised input cycle is only possible in synchronous mode
11	The length of the DP buffer exceeds the size of the DP RAM in the PROFIBUS ASIC
12	Fast-FreeRun mode may not be activated together with synchronous mode

Errors when checking the CfgData

Error code 2

Error code 2 indicates that a byte in the CfgData is not correct. The error argument describes which CfgData byte has been detected as containing an error (the offset of the faulty byte + 1).

Error code 5

Error code 5 indicates that the length of the digital outputs (in bytes) calculated from the CfgData is not correct. The error argument contains the expected byte length.

Error code 6

Error code 6 indicates that the length of the digital inputs (in bytes) calculated from the CfgData is not correct. The error argument contains the expected byte length.

Error code 7

Error code 7 indicates a variety of errors when checking the CfgData. The error argument describes the error.

Error argument	Description
1	The length of the CfgData received is not correct
2	The syntax of the CfgData received is not correct
3	The length of the DP input data that has been calculated from the CfgData is too large
4	The length of the DP output data that has been calculated from the CfgData is too large

Errors during slave start-up

Error code 8

Error code 8 indicates that the length of the DP buffer is greater than the size of the DP RAM in the PROFIBUS ASIC. The error argument contains the difference (divided by 8). DP communication is deactivated.

Error code 9

Error code 9 indicates a variety of errors that may be detected as the device boots. The error argument describes the error.

Error argument	Description
1	The length of the DP input data is too great (too many modules are inserted)
2	The length of the DP output data is too great (too many modules are inserted)
3	The length of the CfgData is too great (too many modules are inserted)
