Demonstration kit for the ST7570 power line modem
with graphical user interface
Introduction
The ST7570 GUI is a software tool that allows interfacing with one or more
STMicroelectronics™ power line modem (PLM) demonstration boards with a personal
computer (PC). Only PLM demonstration boards equipped with the ST7570 device are
supported.
The ST7570 GUI gives the user complete control of the ST7570 device, having access to all
its registers and functions, as described in [2].
The typical application environment (shown in Figure 1) consists of an ST7570 GUI running
on a PC and communicating through a USB connection with a PLM demonstration kit
equipped with the ST7570 product, such as the EVALKITST7570-1 (consisting of a modem
board and a power supply board).

Introduction
The ST7570 GUI gives the user complete control of the ST7570 device, with full access to
all the settings and functions described in [1.]. The GUI can be used to:
●
Establish a connection to the ST7570 modem
●
Configure the ST7570 and manage all its settings
●
Perform any transmission and reception of data and alarms over the power line
Figure 12 shows the main window of the ST7570 GUI. The panel is divided into two
sections:
1.
Node panel: used to control an ST7570 node. In case of multiple nodes connected to
the GUI, the user can switch between the panels through the node panel tabs.
2.
Console: box displaying where all the messages exchanged with the node are
displayed. In the case of multiple nodes, this panel is common to all the nodes.

Adding other nodes
By default, the GUI shows only one node tab in the panel (“Node 1" in Figure 12).
Nevertheless, a single instance of the ST7570 GUI can control more nodes if needed. To
add a new node, left-click on the “Main” menu and then select the menu item “Add node”
(Figure 14).

Basic modem configuration
At power-on, the modem is in IDLE state (refer to [2.]).
In order to perform communication on the power line, the modem must be configured
through the “Configure” button.
This command groups all the basic operating settings of the modem, as resumed in MIB
0x00A1 object (“PLC Configuration”):
●
Operating mode
●
Bit rate
●
Mains frequency
●
Transmission gain
●
Channel frequencies
●
Access layer mode
●
Current control
A confirmation (positive or negative) appears on the console notifying that either the
configuration required has been successfully set or an error has occurred (Figure 22).

PHY layer communication
In order to perform power line communication between two modems:
1.
Open two COM ports, as described in Section 5.3.
2.
Configure the modems, as described inSection 6.1 (first node as PHY client, second
node as PHY server).
3.
Customize (if desired) the payload to be transmitted.
4.
Press the CMD_DataRequest button.

Synchro indication information
As soon as a valid PRE+SSD has been received by the ST7570, the GUI displays
a CMD_SynchroIndication notification in the console box with the related information
regarding signal and noise levels, electrical phase and embedded PGA code.
Figure 25 presents the graphical format of the Synchro Indication notification, and it shows
how to decode the values displayed of signal and noise levels, electrical phase and PGA
code.

PHY data indication information
In PHY mode, the Data Indication exchanged from ST7570 to the PC host gives information
about the payload of the received frame, the levels of signal and noise estimated during
frame reception, and some statistical information about the demodulation procedure.
Figure 26 shows how the ST7570 GUI presents the PHY Data Indication.

Synchronization management
A client modem acquires the timeslot synchronization as soon as a frame is either
transmitted or received; a server node is not allowed to transmit if not synchronized, and
synchronization can be achieved through a valid reception only.
CMD_SynchroStatus
In the Node tab, the CMD_SynchroStatus button can be used to know the synchronization
status of the modem, as it implements the CMD_SyncroStatus command [2.].
Both console and “Sync” box show the modem status: Found(1) or NotFound(2) are the
possible answers, as in Figure 27.

CMD_DesynchroRequest
It is possible to force a rejection of the synchronization through the dedicated command
CMD_DesynchroRequest. When pressed, the CMD_DesynchroRequest button in the node
tab allows this request to be sent. The execution of this command does not generate any
answer notification and, therefore, the console does not show any message.

MIB operations
In addition to basic modem configuration, explained in Section 6.1, as described in the
IEC61334-5-1 standard, there are several other parameters that influence modem behavior
when configured as MAC; all these parameters belong to the MIB and are accessible
through MIB write and read operations.
Figure 29 shows the panel that appears once the “MIB” button in the node panel is pressed.

The MIB parameters allowing basic operations at MAC layer are:
1.
Addresses: Local MAC address, Initiator MAC address, FIMA and LIMA, and MAC

The MIB panel allows to write and read all the MIB objects listed and described in [2.]. The
object name used in the label is the same as in [2.] and the object index is shown on the
tooltip.
For all MIB objects, the “W” button close to the corresponding box name allows to write the
value set in the box in the ST7570 registers. On the other hand, the “R” button reports the
current value stored in the ST7570 registers and it is displayed in the corresponding box
name.

MAC layer communication
In order to perform communication in MAC mode, follow the steps listed in Section 6.2
making sure the operating mode is set to MAC instead of PHY.
5.4.1
MAC frame transmission
As described in [3.],the standard MAC frame is made up of several parameters that can be
set directly in the GUI, as shown in Figure 33. When the CMD_DataRequest button is
pressed (i.e. the user is requesting a packet transmission), the ST7570 GUI software sends
a proper command to the modem with the parameters values.
Figure 33. MAC layer frame composition
If the communication is correctly performed, the console displays the successful Data
Confirm notification in the client side and the Synchro Found and Data Indication
notifications in the server side.

Statistic information
Several MIB variables (accessible through indexed MIB write and read operations) allow
a complete analysis of the communicating behavior and performance of the modem set in
MAC mode.
The writing operation on these statistic variables causes a reset to default values and the
Reset Count's button resets all the counter values.

Alarm services
Once synchronized, the node can transmit, receive, and repeat alarms according to the
settings stored in the following MIB objects:
1.
Alarm Repetition number, Alarm Before Indication number, Alarm Reject Window
number: MIB object 0085h in [2.].
2.
Disable Alarm Indication, Disable Alarm Repetition, Disable Alarm SN Indication: MIB
object 0086h in [2.].

In case of alarm transmission, the console displays the successful Alarm Confirm
notification in the client side and the Alarm Indication notification with the total number of
received alarms in the server side.

Through MIB alarm counters (MIB object 0083h, 0084h in [2.]), it is also possible to know
the total number of transmitted and received alarms (these values depend on the alarm
setting):

Repeater Call
The ST7570 GUI allows the user to manage the Repeater Call for both MAC Client and
Server nodes. In order to activate the automatic recognition of the Repeater Call procedure,
the “RC Request Catch” setting must be ticked as in Figure 42.

Repeater Call for client nodes
The Repeater Call service is started by a Client node in accordance with the details
presented in [2]. By pressing the CMD_RC Request button with the parameters presented in
Figure 43 properly filled, the GUI performs both operations:
●
send a MAC data request command to the connected modem following the upper
protocol layer specifications for Data Payload; the Payload window automatically
switches to the RC Request (BASIC) item; the data transmission takes into account the
credit parameters expressed in the GUI (the IC parameter must be greater than 0 so
that the modem can accept the RC Request)
●
send an RC Request to the modem while powerline transmission is in progress to
respect the RC mechanism, with the TX_POS, RC_THRESHOLD parameters
expressed in the GUI.

Repeater Call for server nodes
In order to activate the Repeater Call service for server nodes, the MIB object 000Bh
(repeater settings) must be written to either a “No” or “Yes” value through the referred ring
menu from the MIB panel, as in Figure 44.
