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.

Master Driver Mode

In Master Mode, the MVI46-DFCM module is responsible for issuing read or write

commands to slave devices on the DF1 network. These commands are user

configured in the module via the Master Command List received from the SLC

processor or issued directly from the SLC processor (event command control).

Command status is returned to the processor for each individual command in the

command list status block. The location of this status block in the module's

internal database is user defined. The following flow chart and associated table

describe the flow of data into and out of the module.

Step Description

The Master driver obtains configuration data from the SLC processor. The configuration

data obtained includes the number of commands and the Master Command List. These

values are used by the Master driver to determine the type of commands to be issued to

the other nodes on the DF1 network (Refer to the MVI46-DFCM Module Set Up Guide).

After configuration, the Master driver begins transmitting read and/or write commands to

the other nodes on the network. If writing data to another node, the data for the write

command is obtained from the module's internal database to build the command.
