Note: The way these files are emulated depends of the First File and File Size parameters. The
previous example shows using the First File parameter set to 7 and the File Size parameter set to
200.
In order to retrieve data from the module's database register 200, the remote
Master would issue a command using the address N8:0. In order to interface with
database base register 405, the remote Master would use the address N9:5. All
the data in the module is available to a remote host. This permits the host device
to remotely configure the module and view the status data.
5.4 Error Codes
The module error codes are listed in this section. Error codes returned from the
command list process are stored in the command list error memory region. A
word is allocated for each command in the memory area. The error codes are
formatted in the word as follows: The least-significant byte of the word contains
the extended status code and the most-significant byte contains the status code.
Use the error codes returned for each command in the list to determine the
success or failure of the command. If the command fails, use the error code to
determine the cause of failure.
