Ethernet Cable
The maximum cable length between the Ethernet port and a 10/100Base-T port
on an Ethernet hub (without repeaters or fiber) is 100 m (328 ft).
Security Considerations
IGMP (Internet Group Management Protocol) is used for IPv4 multicast. A
multicast is communication between a single sender and multiple receivers on a
network. IGMP is used to exchange membership status data between IPv4
routers that support multicasting and members of multicast groups. A router is
an intermediary device on a communication network that expedites message
delivery by finding the most efficient route for a message packet within a
network, or by routing packets from one sub-network to another. A sub-network
is a separate part of an organization’s network identified through IP addressing.
PanelView Plus terminals provide level 2 (full) support for IPv4 multicasting
(IGMP version 2) as described in RFC 1112 and RFC 2236.
SNMP (Simple Network Management Protocol) is used for internal network
management and is not supported.
Ports 137 and 138 are normally open to support the NetBIOS protocol used by
Windows CE.NET similar to other Microsoft and IBM network operating
systems.
Table 43 - Ethernet Cable Requirements
For These Terminal Models Use this Ethernet Cable
1000 terminals Belden 7921A shielded CAT5E cable according to TIA 568-B.1 and RJ45 connector
according to IEC 60603-7 for compliance with Marine emission limits and the
European Union 89/336/EEC EMC Directive.
400 and 600 terminals Use category five, twisted-pair cables.
You can use a standard Ethernet cable or a crossover cable, such as catalog number
2711P-CBL-EX04, when connecting directly to a logic controller or switch.
WARNING: Do not connect or disconnect any communication cable with power
applied to this device or any device on the network. An electrical arc could cause
an explosion in hazardous location installations. Be sure that power is removed
or the area is nonhazardous before proceeding.
