MVI56E-MCM 连续传输到ControlLogix处理器

MVI56E-CM模块返回一个33字的状态数据块，可用于

确定模块的运行状态。此数据位于模块的数据库中

在寄存器15270至15302处以及在配置中指定的位置处。此数据为

与每个读取块一起连续传输到ControlLogix处理器。对于

状态数据对象的完整列表，请参阅MVI56E-CM状态数据定义。

5查看错误状态表

每个单独命令的命令执行状态和错误代码存储在

主命令状态/错误列表，保存在模块的内部存储器中。有

查看此数据的几种方法。

查看监控Modbus端口中的命令状态、从属状态和端口状态

信息

配置命令错误指针参数（＜CmdErrPtr＞）以复制

状态/错误值输入模块内存的用户数据库区域。

将此表复制到ReadData区域的一个部分，您可以在

ControlLogix控制器标记数据库中的<READDATAARRAY>标记阵列。你可以

将这些值用于通信状态监视和报警。

o<CMDERRPTR>=“MCM.CONFIG.PORTX.CMDERRPTR”

o<READDATAARRAY>=“MCM.DATA.READDATA[X]”

这些变量将保存示例程序或Add-On中的文字标记名称

指示使用这些变量来适应未来的梯形图或标记更改，同时

保持向后兼容性

The MVI56E-MCM module returns a 33-word Status Data block that can be used to

determine the module’s operating status. This data is located in the module’s database

at registers 15270 to 15302 and at the location specified in the configuration. This data is

transferred to the ControlLogix processor continuously with each read block. For a

complete listing of the status data object, refer to MVI56E-MCM Status Data Definition.

5.8.1 Viewing the Error Status Table

Command execution status and error codes for each individual command are stored in a

Master Command Status/Error List, held in the module’s internal memory. There are

several ways to view this data.

View Command Status, Slave Status and Port Status in the Monitoring Modbus Port

Information .

Configure the Command Error Pointer parameter (<CmdErrPtr>) to copy the

status/error values into the User Database area of module memory.

Copy this table to a section of the ReadData area, where you can view it in the

<READDATAARRAY> tag array in the ControlLogix controller tag database. You can

use these values for communications status monitoring and alarming.

o <CMDERRPTR> = "MCM.CONFIG.PORTX.CMDERRPTR"

o <READDATAARRAY> = "MCM.DATA.READDATA[X]"

These variables would hold the literal tag names in the sample program or Add-On

Instruction. Use these variables to accommodate future ladder or tag changes while

maintaining backward compatibilit
