5.3.1 MBS.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
MBS.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 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 with 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
5.3.2 MBS.DATA
This structure contains the Read Data and Write Data arrays for processor-to-
module communication.
Tag Name
Description
MBS.DATA.ReadData
Data area copied from the module to the processor. This array
stores the Modbus data coming into the module from the
Modbus network.
MBS.DATA.WriteData
Data area copied from the processor to the module. This array
stores the outgoing data sent from the module to the Modbus
network.
5.3.3 MBS.CONTROL
This array handles special tasks requested by the processor.
MBS.CONTROL.PortControl
This array allows port commands to be controlled by the processor.
Tag Name
Range
Description
MBS.CONTROL.PortControl.
Set
0 or 1
Sends Port Control to module
MBS.CONTROL.PortControl.
Get
0 or 1
Reads Port Control from module
MBS.CONTROL.PortControl.
Portx
n/a
Definition of Port x Control
MBS.CONTROL.PortControl.
Portx.Active
0 or 1
Port Control: Disable = 0, Enable = 1
MBS.CONTROL.PortControl.
Portx.CmdEnableBits[x]
0 or 1
Index of command to be controlled. Example:
Command 20 in port 1 command list can be controlled
at CmdEnableBits[1].3. This is the 20
th
bit offset.
