Note: Messaging is only supported when the MVI46 is Class 4.
To configure the class of the MVI46, use the command line options shown below
when loading the MVI driver MVI46BP.EXE. If no options are given, the MVI46
MVI driver defaults to Class 4, 32 words of I/O, and M0 and M1 sizes of 1024
words (module ID = 13635).

Usage:
C:\MVI46bp.EXE [-iomix=n] [-class=n] [-m0size=n] [-m1size=n]
where:
- iomix=n sets the I/O image sizes. Valid values for n are:
0 => 2 words of IO 5 => 12 words of IO
1 => 4 words of IO 6 => 16 words of IO
2 => 6 words of IO 7 => 24 words of IO
3 => 8 words of IO 8 => 32 words of IO (default)
4 => 10 words of IO
- class=n sets the module class. Valid values for n are:
1 => Class 1 (Messaging disabled)
4 => Class 4 (Messaging enabled, default)
- m0size=n sets the number of words for the Messaging
receive buffer, default m0size=1024
- m1size=n sets the number of words for the Messaging
send buffer, default m1size=1024
NOTE: m0size + m1size must be less than 16320 words.
When configuring the Host Controller for the MVI46, the programming software
requires the Module ID for each module in the system. The Module ID for the
MVI46 depends upon the configuration set by the driver. When the driver is
loaded, it prints to the console the Module ID value that can be entered into the
programming software for the Host Controller. For example, the default
configuration prints the following information:
[C:\]MVI46bp

Class 4
IO mix 8 = 32 words of IO
M0 File size = 1024 words
M1 File size = 1024 words
SLC Module ID = 13635
The first line, IRQPRIORITY=1, assigns the highest interrupt priority to the I/O
backplane interrupt. The next line loads the backplane device driver. In this
example, the backplane device driver file (MVI46BP.EXE) must be located in the
root directory of the ROM disk. In the case of the MVI46, the module I/O is set
when the backplane driver is loaded. The module is set to class 4 with a 3000
word M0 file and a 10000 word M1 file. The Module ID for installing and
configuring the module in the ladder program will be printed to the console when
the backplane driver is loaded.
