2.2.5 SIE Client x Commands
The SIE Client x Commands section of the configuration sets the Siemens
Industrial Ethernet Client command list. This command list polls Siemens
Industrial Ethernet server devices attached to the Siemens Industrial Ethernet
Client port. The module supports numerous commands. This permits the module
to interface with a wide variety of Siemens Industrial Ethernet protocol devices.
The function codes used for each command are those specified in the Siemens
Industrial Ethernet protocol. Each command list record has the same format. The
first part of the record contains the information relating to the MVI56E-SIE
communication module, and the second part contains information required to
interface to the Siemens Industrial Ethernet server device.
Command List Overview
In order to interface the module with Siemens Industrial Ethernet server devices,
a command list must be constructed. The commands in the list specify the server
device to be addressed, the function to be performed (read or write), the data
area in the device to interface with, and the registers in the internal database to
be associated with the device data. The Client command list supports up to 16
commands.
The command list is processed from top (command #1) to bottom. A poll interval
parameter is associated with each command to specify a minimum delay time in
tenths of a second between the issuances of a command. If the user specifies a
value of 10 for the parameter, the command will be executed no more frequently
than every 1 second.
Commands Supported by the Module
The format of each command in the list depends on the Siemens Industrial
Ethernet Function Code being executed.
The following table lists the functions supported by the module. The type of
functions that will be supported will also depend on the server device and what it
can support. Below are examples of S7-200, S7-300 and S7-1200 functions that
are supported using MVI56E-SIE module.
