G 3800 X036 Operation Manual
August 2006
The following steps are required for setting up a Mastergenerator for Dupline-Online operation:
•
Select the media for transmitting the Log Records to the Central Server (GSM Modem or the Internet)
• Select the desired Dupline addresses for event-based logging and enter text descriptions
• Select the desired Dupline addresses for time-based logging and enter text descriptions, scaling factors,
engineering units and logging time intervals
• Download the configuration file to the Mastergenerator
• Generate a special Dupline-Online configuration file to be exported to the Central Server via the Internet
In the following sections of Chapter 6, it is described how to go through these steps (except for download of
the configuration file to the Mastergenerator, which is described in sec. 1.2.1)
6.3. Dupline-Online Transmission Media
6.3.1. Using GSM Modem
The procedure for configuring the Mastergenerator for sending the Log Records to the Central Server via GSM
Modem is described in Chapter 5 (GSM Modem Functions).
6.3.2. Using the Internet
In order to use the Internet for sending the Log Records to the Central Server, "COM2 Operation Mode" must
be set to "Automatic Data Logging" (see sections 4.4 and 4.6). Also, "COM2 Baud Rate" must be set to 9600.
This is the only configuration required in the "Communication Setup" menu in order to set up Dupline-Online
operation. In terms of hardware, an external RS232-to-Ethernet converter (item number ETHCONV1) is
required. The converter needs to be connected to COM2 of the Mastergenerator by means of the RS232 cable
included in the ETHCONV1 package. The connection to the Ethernet is carried out by means of a
standard Cat 5 Ethernet cable. In the majority of cases, this cabling is all that needs to be done to bring the
converter into operation, because it is pre-configured to send the Log Records to www.Dupline-Online.com
and to be installed on a network with a dhcp server, which automatically assigns an IP address to it. If a dhcp
server is not available on the network, it is easy, however, to assign a specific IP address to the converter.
It is always the Mastergenerator that initiates the communication from inside the local network by opening a
TCP/IP socket connection to the Central Server. Because of this, there is usually no need to change any setup
in the firewall in the network or in the converter. This is only necessary in those cases, where the firewall is fil-
tering connections made from inside of the network, and this is quite unusual, because then free Internet
access is also inhibited.
6.4. Event-based logging
This is the standard (and only) logging method for Digital signals, but it can also be used for Analink signals.
Whenever a Digital Dupline Address, which has been configured for logging, changes status, a Log Record is
generated and saved in non-volatile memory. If configured to do so (see section 6.2 and 6.3), the Master -
generator will also send the Log record via GSM or the Internet to the Central Dupline-Online WebServer,
where it is saved in a database. The Log Record contains the Address, the new status of the signal (ON or
OFF) and time/date/year of the event. Event-based logging of an Analink signal takes place whenever the
value crosses the limits defined in the setup of the Analink address. The Log Record contains the Address, the
Analink value and time/date/year of the event.
The selection of which signals shall be logged as events is performed under the setup menu for each
individual channel.
