Cable Connections - MVI56E-FLN
The MVI56E-FLN module has the following functional communication
connections installed:
One 10/100 Mbps Ethernet port (RJ45 connector, labeled E1) for
configuration and troubleshooting only
One 10/100 Mbps Ethernet port (RJ45 connector, labeled E2) for FL-net
application data transfer only
4.9.1 Ethernet Connection
The MVI56E-FLN module has two RJ45 ports located on the front of the module
labeled "E1", to be used only for configuration and troubleshooting, and "E2", to
be used only for connection to the FL-net FA Control Network.
Warning:
The MVI56E-FLN module is NOT compatible with Power Over
Ethernet (IEEE802.3af / IEEE802.3at) networks. Do NOT connect the module to
Ethernet devices, hubs, switches or networks that supply AC or DC power over
the Ethernet cable. Failure to observe this precaution may result in damage to
hardware or injury to personnel.
Important:
The module requires a static (fixed) IP address that is not shared with
any other device on the Ethernet network. Obtain a list of suitable IP addresses
from your network administrator BEFORE configuring the Ethernet port on this
module. The last digit of the IP address for port
E2
is the FL-net node number of
the module on the FA Control network.
4.9.2 Ethernet Cable Specifications
The recommended cable is Category 5 or better. A Category 5 cable has four
twisted pairs of wires, which are color-coded and cannot be swapped. The
module uses only two of the four pairs.
The Ethernet ports on the module are Auto-Sensing. You can use either a
standard Ethernet straight-through cable or a crossover cable when connecting
the module to an Ethernet hub, a 10/100 Base-T Ethernet switch, or directly to a
PC. The module will detect the cable type and use the appropriate pins to send
and receive Ethernet signals.
Ethernet cabling is like U.S. telephone cables, except that it has eight
conductors. Some hubs have one input that can accept either a straight-through
or crossover cable, depending on a switch position. In this case, you must ensure
that the switch position and cable type agree.
Refer to Ethernet cable configuration (page 143) for a diagram of how to
configure Ethernet cable.
