3 ETHERNET/IP NETWORK INSTALLATION

This chapter presents recommendations related to equipment installation in an EtherNet/IP network.

3.1 IP ADDRESS

Every equipment in an Ethernet network needs an IP address and subnet mask.
The IP addressing is unique in the network, and each equipment must have a different IP. The subnet mask is used
to define which IP address range is valid in the network.
The SSW900 soft-starter allows the use of two methods for programming these features, programmable via C8.3.4:
Parameters: uses the configurations of IP address, mask and gateway as programmed on equipment parameters.
DHCP: enable the configuration of the SSW900 via DHCP server. The DHCP can automatically assign IP
addresses, subnet mask, etc. to the devices on the network. The configurations performed via parameters
are disregarded.
✓
NOTE!
After changing these properties, for the changes to take effect, the equipment must be turned off and
on again, or requesting the settings update via C8.3.1.

3.2 COMMUNICATION RATE

The Ethernet interfaces of the SSW900 soft-starter can communicate using the 10 or 100 Mbps rates in half or full
duplex mode.
✓
NOTE!
It is important that, for each Ethernet connection made between two points, the baud rate and the
duplex mode are set to the same option. If the option AUTO is used in one of the points, you must set
the other point also to AUTO, or to half duplex mode.

3.3 CABLE

Recommended characteristics for the cable:
Standard Ethernet cable, 100Base-TX (FastEthernet), CAT 5e or higher.
Shielded cable.
Maximum length between devices: 100 m.
For installation, it is recommended the use of shielded Ethernet cables specific for use in industrial environment.

3.4 NETWORK TOPOLOGY

To connect SSW900 soft-starter in an EtherNet/IP network, usually the star connection is made using an industrial
switch.
