Module Configuration with RSLogix

2.3.2 Data Object (MV69101M_DATA)

The MV69101M_DATA object is defined in the example ladder logic to
demonstrate how the data from a module can be stored in the processor. This
object stores data to be sent from the processor to the module (WriteData) and
data to be sent from the module to the processor (ReadData). A structure of this
type can be constructed for each session or sector or can be set as in the
example as one large database. The user should decide the best data storage
method for their application. Another factor in determining the database layout is
the simplicity of the ladder logic. In the example ladder logic, only one data copy
operation is required for each data type as the data is packed in the module. If
separate data areas are defined for each session, more copy instructions would
be required. This could simplify data management. The structure of the object
used in the example logic is shown in the following example:
Name
ReadData
WriteData

Configuration File

In order for the module to operate, a configuration file (IEC101M.CFG) is
required. This configuration file contains all the information required to configure
the module's master drivers, set up the databases for the controlled devices and
established a command list. Each parameter in the file must be set carefully in
order for the application to be implemented successfully. The Reference chapter
contains an example listing of a IEC101M.CFG file.
The configuration file is separated into sections, with topic header names
enclosed in the [ ] characters. The configuration file consists of the following
sections:
[Section]
[Backplane Configuration]
[IEC-870-5-101 Master]
[IEC-870-5-101 Master Port 0]
[IEC-870-5-101 Master Port 1]
[IEC-101 Master Session x]
[IEC-101 Master Session x Sector y]
[IEC-101 Master Commands]
After each section header, the file contains a set of parameters. Unique labels
are used under each section to specify a parameter. Each label in the file must
be entered exactly as shown in the file for the parameter to be identified by the
program. If the module is not considering a parameter, look at the label for the
data item. Each parameter's value is separated from the label with the ':'
character. This character is used by the program to delimit the position in the
data record where to start reading data. All data for a parameter must be placed
