4.18 Frequently Asked Questions
How do I set up the MVI46-DFNT?
The module must be configured using RSLogix in order to be recognized by the
software. You do not have to worry about this step if you are using the sample
ladder logic shipped with the module since the module is already configured in
the I/O configuration.
Refer to the User Manual for information about each parameter.
Finally, you must copy the sample ladder logic to your ladder application. It is
strongly suggested that the sample ladder logic is used.
How does the MVI46-DFNT communicate with the SLC?
The communication between the SLC and the MVI46-DFNT is performed through
the backplane. The module’s internal database in constantly copied to the M1 file
and vice versa. The SLC uses a simple COP instruction to write (or read) values
to the module as described in the sample ladder logic.
How do I monitor the MVI46-DFNT internal database?
You can use the debug port interface by selecting the [D] key (Database View).
The database can be viewed in decimal, hexadecimal or ASCII format.
You can also copy the M1 file (which is a copy of the MVI46-DFNT database) to
the SLC memory.
How do I set up the MVI46-DFNT IP address?
Using an ASCII terminal to access the debug port, you can select the network
menu by selecting "@". You can then copy the current network configuration file
to a PC (WATTCP.CFG).
How can I send commands from the MVI46-DFNT?
You must add commands to the current command list in the configuration file and
transfer the file to the MVI46-DFNT.
Can I control the commands from ladder logic?
Yes, using blocks 3000 to 3002, you can change the Enable field on commands
that are already defined in the configuration file. You can disable or enable
(continuously or conditional).
How do I transfer files to the module?
The configuration file can be transferred using the ASCII Terminal used to
connect to the debug port. Selecting option "R" will cause the module to wait for
a configuration file. The user should then send the file using the menu bar in the
ASCII Terminal software.
