Network Connectivity
AWIN GW120 has built-in four ports. Ports P1-P2 can be connected to an Ethernet switch. The
switch can be part of a host network. A typical host system on the network can be a PLC or
Automation controller using ModbusTCP protocol to communicate to the gateway.
The AWIN GW120 is compatible with networks that use a Dynamic Host Control Protocol
(DHCP) server for allocating IP addresses. AWIN GW120 supports both static and dynamic IP
address assignment.
The ethernet switch port connected to the AWIN GW120 gateway shall have Flow
Rate limiter enabled. Overall bandwidth should be capped to 10Mbps (recom-
mended). Avoid mixing field network with other networks, such as control and cli-
ent/server network. AWIN GW120 belongs to a field network only.
AWIN GW120 is not an interfacing device. Typically, it is located between level 0
(process) and level 1 (basic control) hierarchy of the automation pyramid. It shall be
installed behind switch(es) and firewall(s) from the higher levels.

Hard Reset
A hardware reset restores the default IP address of
172.16.16.10
(subnet:
255.255.255.0
) and
resets the AWIN GW120 to factory default settings.
To initiate a hardware reset, use a screwdriver or something alike to press and hold the “re-
set” button, located on the front of the device.
With unit powered on and fully booted:
1.
Hold Reset button for 10 seconds and release button.
2.
About 10 seconds later the ST and MESH (if it was on) turn off.
3.
Gateway will wait ~20 seconds before flashing LEDs.
4.
ST and RED LED flash for ~30 seconds.
5.
Gateway's ST LED turns to solid GREEN and the system is ready.
