Modbus TCP
This section must be configured only in case you want to interrogate an external server. The options
are:
▪
Swap ON
: the datalogger includes a Modbus TCP server. For example, it can be interrogated by
a SCADA. Since each value is expressed by two 2-bit registers, this field allows for specifying
which register is the upper one and which is the lower one. It is explained in more detail in the
section Modbus TCP Server.
▪
Auto close
: Time, in seconds, to close the socket in case the status of the port Modbus TCP is
inactive.

GPRS parameters
To configure the GPRS connection of the datalogger
delete the field Gateway IP and type an asterisk *
instead. Then, save the changes and restart the datalogger.

verify that the GPRS connection is working. There are three possible values: zero (
0
), if you
want the datalogger to connect to the URL set by default;
NO
, if you don't want the datalogger
to check the ping (this can lead to faults); or, if wanted, the user can type a particular URL.
▪
If after 3 pings the datalogger does not receive any reply, the GPRS connection is restored.
The fields: APN, User and Password from the section GPRS Parameters must always contain
something. If you are not going to use the GPRS connection, put an asterisk (*)
