5.7.2 General Command Structure
DF1 Master Port Command
Structure (File for each Master
Port)
Description
Enable/Type Word
0=Disabled, 1=Continuous, 2=Conditional and 999=Poll. The
conditional type only applies to the write functions.
Virtual Database Address
This parameter defines the virtual database register to be
associated with the command.
Poll Interval
Minimum time in tenths of a second to wait before polling with this
command.
Count
Number of data values or registers to be considered by the
function.
Communication
Module
Information
Swap Type Code
Swap type code for command: 0=None, 1=Swap words, 2=Swap
words & bytes and 3=swap bytes in each word.
Node Address
Node address of unit to be reached on the data highway.
Function Code
This parameter defines the module function code to be
associated with the command. Each function code requires a set
of parameters to construct the DF1 message.
Device
Information
Parameters
Up to four parameter fields can follow the function code field to
define the element or data register to be considered by the
function.
Note that the Node Address field of the serial implementation has been
expanded to two fields: IP Address and Slot Number. This is required for network
support. The IP Address specifies the IP address of the device to reach on the
network. The Slot Number has specific meaning determined by the processor.
For ControlLogix processors, the Slot Number is the location in the ControlLogix
rack of the processor. For a four-slot rack, this parameter would have a valid
range of 0 to 3. For the PLC5 and SLC family of processors, the Slot Number
parameter is always set to -1. These processors do not have a slot number in the
path field as the Ethernet interface is resident on the processor.
The following tables define the parameters required for each function.
