5.3 MBTCP 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
MBTCP.CONFIG Configuration information
MBTCP.DATA MBTCP input and output data transferred between the processor
and the module
MBTCP.CONTROL Governs the data movement between the PLC rack and the
module
MBTCP.STATUS Status information
MBTCP.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 MBTCP.CONFIG
When ProSoft Configuration Builder (PCB) downloads the configuration file from
the PC to the processor, the processor stores the configuration file data in the
MBTCP.CONFIG.FileData array. Its CRC is also included in this array.
You cannot edit this array directly. You must use PCB to edit the module
configuration since PCB calculates a unique CRC to protect data integrity. Any
change to the configuration parameters directly in this array do not match the
calculated CRC.
Tag Name Description
MBTCP.CONFIG.FileData
This parameter contains the MBTCP configuration data after it
has been downloaded from PCB. It is displayed in ASCII format.
Note: MBTCP configuration changes cannot be made directly in
this array; the configuration must be downloaded with PCB.
MBTCP.CONFIG.FileSize Configuration file size (MBTCP.CONFIG.FileData array) in bytes.
MBTCP.CONFIG.FileCRC32 CRC checksum of the configuration file stored in the array.
MBTCP.CONFIG.FileStatus Configuration file status. 0 = No file present, 1 = File present
