Functions and Features
The TGW-100 is a gateway for the connection between automation devices and servers
(SCADA, PLC, PC), mainly used on the master side (i.e. control rooms, SCADA
servers etc.) to make a connection between devices based on serial protocols and a
TETRA network.
The TGW-100 supports nearly all standard and proprietary serial communication
protocols. It has two serial data interfaces (RS-232 or RS-485/422) and an Ethernet
(10/100 Mbits/sec) port. For the data transmission on the TETRA radio network, either
of two modes can be selected: SDS based communication (on supported infrastructures)
or packet data based transmission (working on any infrastructure which allows the
connection of IP based equipment to the TETRA switch).
The main function of the TGW-100 is to connect serial based equipment to the TETRA
network with a direct IP connection to the TETRA switch. This will save the air
interface link on the master side, where normally the data to all outstations will be
routed through. As IP based protocols can directly be connected to the TETRA switch,
serial based protocols must use a gateway device for being connected to the
infrastructure, featuring also a protocol address detection and translation into addresses
which can be handled by the TETRA network (ISSI or IP addresses).
The use of a gateway instead of a radio link on the master side will dramatically
decrease the load on the base station located to the master site and also reduce the
latency by the half of time. It will eliminate the bottleneck of data communication which
is sitting on the master side, where all data needs to pass, if a normal TETRA radio is
used to connect the control room or master SCADA to the TETRA network.
The TGW-100 is delivered as a 19" rack version as "TGW-100R". The rack version
allows the easy mounting in a server cabinet and includes two redundant power
supplies. Up to 3 additional TGW-100 plug-in modules can be placed into the basic
TGW-100R enclosure, giving a total of 4 TGW-100 modules with overall 8 independent
serial ports.
The TGW-100 is also available in a rugged aluminum housing compatible with standard
DIN rail mounting. The wide power input voltage range of 12-24 VDC [+/- 20%] makes
it easy to integrate the unit into monitoring and control systems.
