LSI LASTEM M-Log – User’s manual
51
One PC server with Windows operating system (Window XP or next version, Windows
Server 2003 or next version), connected to Internet with a public IP address;
LSI LASTEM
CommNetEG code BSZ306.2
program with use licence enabled for GPRS
connections (only for transmission through TCP socket).
M-Log must be configured through
3DOM
program, in order to use GPRS modem and transfer the
elaborated data with selected timing; the GPRS modem can be used only with serial port 1. In the
configuration through 3DOM software, remember to enable with
Yes
the field
Modem powered with
actuator
in the
Serial communication port 1
window when the modem is powered using actuator 3
(recommended solution).
GPRS connection happens according to the spontaneous transmission rate programmed inside the
system; therefore it happens according to the programmed timing (on the initiative of the
instrument); you can also make a manual data transfer by pressing the button
. The remote
computer (that collects the data) consists of one TCP server, set on IP public address. The address
of this server has been programmed inside GPRS modem connected to M-Log.
There are two different transmission’s modes:
Through TCP socket;
Through FTP protocol.
The TCP socket connection allows the use of minimum quantity of IP packets, and for this reason
it’s cheaper than FTP protocol. Moreover one server (no special software installed in it) can transfer
the data through TCP protocol.
In addition to the above-described parameters, set the following parameters through 3DOM
software in according to the selected transmission’s mode:
for TCP mode, select
Switched off and on in case of failure
option in
Serial communication port
1
window;
for FTP mode, select
Power on/off due to actuation logic
option in
Serial communication port 1
window to set the modem to switch off once a day. Then configure an actuation logic for leave
the modem turned on all day except for a minute that will remain turned off; it is advisable to
turn on the modem at least two minutes before the transmission.
M-Log will transfer the data to the operative centre at set timing. The parameters of the operative
centre (IP address, IP port, user name, etc) have been specified inside
config.ini
configuration file
(stored inside GPRS modem). In case of transmission through TCP socket the operative centre must
be equipped with LSI LASTEM
CommNetEG code BSZ306.2
program. In case of transmission
through FTP protocol, one FTP server must be available and working.
