Definition of
Gateway
The Atrium / TCP Gateway (simply referred to as Gateway, throughout this
document) is a software application used to connect an Atrium coprocessor to the
TCP network using existing PC connections (software and hardware connections).
It runs on Windows 2000 or XP operating systems.
It can either use an Ethernet or modem connection.
With a modem connection, you need to use the RAS for Atrium (See Configuring the
"RAS profile" screen, p. 22) function and communicate using the PPP protocol.
The communication initiative can come from a PLC connected on the X-Way
network.
Existing PC connections, as well as Ethernet and modem connections, can be used
simultaneously.

The Gateway can be used to communicate on the Ethernet network in Modbus and
Uni-TE.
Modbus and Uni-TE messaging services are identical to those of Ethernet Premium
communication modules, whatever the Ethernet connection:
l with the ISA card: TSXETHPC101M,
l with the PCI card: TCCETH01.
The user can also use applications such as OPC, PL7 and Vijeo Look
simultaneously.

the Gateway uses the Windows RAS function to communicate on the STN
modem link.
l
compatibility and transparency with X-Way drivers:
X-Way transparency is provided with the Atrium card.
General presentation
Operate mode
Installation
The Gateway software is installed using a CD-ROM which, once inserted in the
drive, automatically starts the installation of the software onto the hard disk of a PC
or Magelis iPC (if the CD-ROM automatic start-up option under Windows is
activated).
Hardware and
software
configuration
This software is based on Windows interfaces enabling easy configuration of the
parameters according to needs. This tool is used to set up a static configuration of
the Gateway.
During validation, all parameters are checked and recorded in a file.
There is no dynamic reconfiguration of the Gateway. All reconfigurations require the
Gateway software to be restarted.
The Gateway operates under the following Windows operating systems:
l Windows 2000,
l Windows XP.
It can only be run on a PC or Magelis iPC with a built-in Intel processor. PCs with
built-in multi-processors are also supported.
There is no version of Online mode (Run Time) for platforms without a built-in Intel
processor.
Online mode
This mode can be launched automatically (See Detailed description, p. 19) on startup of the system (PC or Magelis iPC). A service window opens before user identification and provides information on the status of remote PLCs on the network.
Once the configuration has been recorded, no user operation is required on starting
up the system.

Product configuration
Configuring the "RAS profile" screen
At a Glance
The Gateway supports the management of the RAS (Remote Access Service), used
normally for communication by modem via the PPP protocol. Its operation is limited
to an output modem and an input modem.
Note: before each configuration the modem(s) must be installed first of all on the
PC.
Characteristics integrated in the Gateway:
l initialize the RAS connection in order to accept a remote PPP connection,
l initialize the RAS connection in order to create a PPP connection to a remote
RAS server:
l dynamically, when it is necessary to establish a remote TCP connection.
In the case where there are two modems, a client link and a server link can both be
active at the same time.
If several modems (internal or external) are installed, all incoming connections will
be accepted regardless of the modem used.
Once communication is established, the communication is two-way (See Uni-TE
and Modbus message handling, p. 27).

l this zone allows you to select the modem on which the PC's outgoing calls are
made (dial out or Atrium clients).
For incoming (Dial in) calls, the Gateway accepts all calls from all the modems
configured on the PC. However, the PC must be configured to accept incoming
calls. This configuration is set up using the Windows "Network and Dial-up
Connections" window.
l the "Modem" button activates the Windows "Modems" window.
Note: if two STN lines are available, one modem can be used for outgoing calls
(Atrium Clients), and the other for incoming calls, for remote connections to Atrium.
Server parameters:
these parameters enable you to configure controls for incoming calls (dial in).
23
Product configuration
Note: the PC must be configured to accept incoming calls.
l
the "Enable" checkbox enables or disables incoming calls. If the box is not
checked (disabled) all incoming calls are ignored.

Uni-TE message handling
TCP server mode
The Gateway is awaiting a remote connection on the previously configured port (port
502 by default). In this case, it acts as server for the exchanges initiated by the
remote stations.
On a Client TCP request, the Gateway opens a connection according to which
access rights are set as "authorized / excluded". This mode is frequently used for a
typical client connection such as PL7 / Unity Pro programming tools.
Note: A maximum of 53 simultaneous connections in server mode are accepted by
the Gateway.
Client TCP mode
The Gateway opens a connection with a remote station on the previously configured
port (port 502 by default) according to the connection parameters in client TCP
mode for a given X-Way address.
In this mode, the Atrium initiates an exchange to a remote station using the
SEND_REQ() communication functions.
When using the Gateway in client mode, a table of 6 bytes corresponding to the
destination address needs to be placed at the start of the send buffer. For further
information, consult the TSX DR NET manual.

Note: in client mode, only the request SEND_REQ is used. This request does not
carry out a consistency check of the input parameters (e.g.: check the number of
data items to be written against the size of the data buffer). This must be checked
by the user.

This program is used to send a Uni-TE request to a remote device with an X-Way
address: 2.4 (16#0402). The request allows 3 bits to be read: %M100, %M101,
%M102.

Uni-TE and Modbus message handling
Modbus messaging
At a Glance
The Gateway uses the Uni-TE messaging service to communicate with the Atrium.
A Modbus / Uni-TE conversion (or vice versa) is automatically carried out by the
Gateway for both modes (client and server) as described below.
Server mode
If a Modbus frame is recognized by the Gateway, Modbus to Uni-TE conversion is
carried out before the request is sent to the PLC. This conversion enables the reply
to be sent back.
Note: for each Modbus remote station, the couple (IP address, {station network}
X-Way) must be configured in the correspondence table:
Client mode
The Uni-TE to Modbus conversion is carried out by Gateway only if the client
connection is identified as a Modbus connection and the X-Way addressing
complies with the Uni-TE to Modbus format.
The correspondence between Modbus function codes and Uni-TE requests is
described in the table below:
