2.1 Module Data
All data related to the MVI46-MBP module is stored in user defined data files and
the module's M1 and M0 files. Files should be defined for each data type to be
used with the module. Additionally, a file should be defined to hold the module
status data. The status data should be copied from the M1 file and placed in the
assigned status file. Read (monitor) data should be copied to the user files from
the M1 file and write (control) data should be copied from the user files to the M1
file.
2.2 Module Configuration
In order for the MVI46-MBP module to function in any of its possible modes, a
minimum amount of configuration data must be transferred to the module. The
following table provides an overview of the different types of configuration data
that the module will require, depending on the operating modes to be supported.
Module
Register
Address Functional
Modes
Affected Name Description
4370 to 4409 Global In
Global Out
Slave
Master General Module
Configuration This section of the configuration data contains the generic
module configuration data, and must be configured for the
module to operate.
4410 to 4449 Global In Input File Map If the module's Input File is to be used to transfer data
from the module to the processor, then this section of
configuration data must be set up.
4450 to 5089 Global In
Master Device Definition If the module's Global Input or Master Mode functionality
is to be used, then this section of configuration data must
be set up.
5090 to 7089 Master Master Command List If the module's Master Mode functionality is to be used,
then he Master Command List must be set up.
Refer to the Reference chapter of this manual for a description of the
configuration of the module.
Important: The module will not function correctly until the Module Configuration Data is received
from the processor with at least the Local Modbus Plus Node Address set to a valid value.
The MVI46-MBP module must be configured at least once when the card is first
powered, and any time thereafter when the parameters must be changed.
Power Up
On power up, the module enters into a logical loop waiting to receive
configuration data from the processor. Upon receipt, the module begins
execution of the command list if present.
