5.3 MBS Controller Tag Overview

You use controller tags to:

 View the read and write being transferred between the module and the

processor.

 View status data for the module.

 Set up and trigger special functions.

 Initiate module restarts (Warm Boot or Cold Boot).

Tag Name

Description

MBS.CONFIG

Configuration information

MBS.DATA

MBS input and output data transferred between the processor

and the module

MBS.CONTROL

Governs the data movement between the PLC rack and the

module

MBS.STATUS

Status information

MBS.UTIL

Generic tags used for internal ladder processing (DO NOT

MODIFY)

The following sections describe each of these controller tag structures in more

detail.

5.3.1 MBS.CONFIG

When PCB downloads the configuration file from the PC to the processor, the

processor stores the configuration file data in the MBS.CONFIG.FileData array.

Its CRC is also included in this array.

You cannot edit this array directly. You must use PCB for configuration edits. All

configuration edits must be done in PCB since a unique CRC is calculated for

data integrity. Any change to the configuration parameters directly in this array

will not match the calculated CRC.

Tag Name

Description

MBS.CONFIG.FileData

This parameter contains the MBS configuration data after it has

been downloaded from PCB. It is displayed in ASCII format.

Note: MBS configuration changes cannot be made directly in this

array; the configuration must be downloaded via PCB.

MBS.CONFIG.FileSize

Configuration file size (MBS.CONFIG.FileData array) in bytes.

MBS.CONFIG.FileCRC32

CRC checksum of the configuration file stored in the array.

MBS.CONFIG.FileStatus

Configuration file status. 0 = No file present, 1 = File present
