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
