Technical Manual
Send SMS
The device can be used for sending test SMS messages. This is useful, for example,
for checking the phone number of the current SIM card.
Default settings
The device can be reset to the factory default settings. When resetting to the factory
settings, the network settings are excluded.
IEC-104 application settings
The IEC 60870-5-104 and IEC 60870-5-101 protocols share the same ASDU level
messaging but differ on the link level. IEC 60870-5-104 is intended for packet-
switched TCP/IP communication and IEC 60870-5-101 for serial communication.
By using the device's IEC 60870-5-104 gateway, the IEC 60870-5-101 slaves, for
example, RTUs, can be connected to an IEC 60870-5-104 master (for example,
SCADA). The device requests events from the IEC 60870-5-101 slave locally and
sends them to the IEC 60870-5-104 master. This eliminates the need to
continuously poll the data remotely and also reduces the communication costs on a
pay-per-use GPRS network. This approach also eliminates the IEC 60870-5-101
parameter problems caused by variable round-trip delays on the GPRS network and
makes the information exchange faster and more reliable.
