To connect to the MASTER, use a standard twisted pair Ethernet
cable with RJ45 connector.
The RJ45 Ethernet connection cable has a variable maximum length,
depending on the type of cable. A common Cat5 shielded cable
can have a maximum length of about 180 m.
• You can connect the Ethernet communication port directly to the
PC, without having to go through other network devices (routers,
switches, hubs, LAN-bridge or the like), but special RJ45 cables must
be used, called “crossover.”
• Normally cables are the “direct” type and allow connection to
network devices such as routers or hubs, but not direct connection
to two PCs (even if there are
currently network cards with
auto-sensing technology, which
recognize the type of cable and
the type of connection, allowing
direct PC-PC connections as well
as using non cross-over cables).
• On side are diagrams of the
two types of cables mentioned
and their connection diagram.
ETHERNET / IP CONNECTION
Ethernet / IP is a real-time industrial protocol which is based on the
Ethernet network.
There are two RJ45 connectors to allow connection of multiple in-
struments in the same network.
Refer to the previous page for connection notes and warnings.
Features:
10 and 100 Mbit operation, Full and Half Duplex
Modbus-TCP server
Up to 128 bytes of I / O fieldbus in every direction.
