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.
