contains the subdirectory:
• /MODBUS: Denition les for the monitored Modbus modules.
• /LOG: Contains the gateway’s system logs (IDSite_DATE.log) and the debug logs,disabled by
default (IDSite_DATE_debug.log).
5.2 Access to the NTP Server
To set its date and time correctly to UTC time, the WebdynModbus synchronises itself with an NTP server
before each connection to the FTP server. By default, the gateway is congured to get the time from
the NTP server “pool.ntp.org”. As this NTP server is accessible only via Internet, the gateway must have
operational Internet access (UDP port 123 must be open for outgoing trafc) for synchronisation to occur.
5.3 Connection via GPRS or Ethernet
Access to the FTP and NTP servers can be done either via an Ethernet connection or a GPRS connection.
5.3.1 Ethernet Connection
For connection to Internet via Ethernet, the following conguration parameters must be correctly informed
to the gateway:
• IP address of the WebdynModbus on the local network (factory IP address: 192.168.1.12)
• Subnet mask
• IP address of the router or ADSL modem
• IP address of the DNS server
5.3.2 GPRS Connection
For connection via GPRS, it is essential to insert an activated SIM card with a DATA option in the gateway,
and to inform it with the following information correctly:
• APN (Access Point Name): Name of the GPRS access point. This depends on the operator and
the type of subscription
• User name and password for connection to the APN
5.3.3 Managing the PIN Code for the SIM Card
The WebdynModbus handles the SIM card’s PIN code automatically, the PIN code cannot be informed to
the gateway. The SIM card must therefore either have no PIN code or have a PIN code set to 0000 when
it is rst inserted.
The management of the SIM card’s PIN code is as follows:
• If the PIN code is deactivated: GPRS communication is operational for the gateway.
