Description 1 Upon module boot-up, the Master driver obtains configuration data from the MBS controller tags. The configuration data retrieved includes port configuration and the Master Command List. Special Commands can be issued directly from the CompactLogix or MicroLogix 1500- LRP processor using Event Commands and Command Control. These command values are used by the Master driver to determine the types and order of commands to send to slaves on the network. 2 After configuration, the Master driver begins transmitting read and/or write commands to slave nodes on the network. If the Master driver is writing data to a slave, the data for the write command is retrieved from the module’s internal database. 3 Once the specified slave has successfully processed the command, it returns a response message to the Master driver for processing. 4 Data received from a slave in response to a read command is stored in the module’s internal database. 5 Status is returned to the processor for each command in the Master Command List.

Page 75 of 159 Important: Take care when constructing each command in the list to ensure predictable operation of the module. If two commands write to the same internal database address of the module, the results are invalid. All commands containing invalid data are ignored by the module. Master Command List For a port to function in Master Mode, its Master Command List must be defined in Prosoft Configuration Builder; refer to Modbus Port x Commands (page 44).
This list contains up to 310 individual entries, with each entry containing the information required to construct a valid command. A valid command includes the following items:  Command enable mode: (0) disabled, (1) continuous or (2) conditional  Source or destination database address: The module database address where data is written or read.  Count: The number of words or bits to be transferred – up to 125 words for Function Codes 3, 4, or 16, and up to 2000 bits for Function Codes 1, 2, or 15. Note: 125 words is the maximum count allowed by the Modbus protocol. Some field devices may support less than the full 125 words. Check with the device manufacturer for the maximum count supported by the particular slave device.
