Step Description
4 Data received from the node on the network is passed into the module's internal
database, assuming a read command.
5 Status is returned to the ControlLogix processor for each command in the Master
Command List.
Refer to the Module Set Up section for a complete description of the parameters
required to define the virtual DF1 master port. Care must be taken in constructing
each command in the list for predictable operation of the module. If two
commands write to the same internal database address of the module, the
results will not be as desired. All commands containing invalid data will be
ignored by the module. The module does not support the PLC-5 ASCII Address
commands (150 to 152) as outlined in the DF1 Command Set documentation.
The following table describes the functions supported by the module and the
format of each command:
