Connecting to an Ethernet Network
The ArmorBlock module supports the following Ethernet settings:
• 10 Mbps half duplex or full duplex
• 100 Mbps half duplex or full duplex
Mode selection can be automatic, based on the IEEE 802.3 auto negotiation
protocol. In most cases, using the auto negotiation function results in proper
operation between a switch port and the ArmorBlock module.
With RSLogix 5000 programming software version 18 or later, you can manually
set the communication rate and duplex mode of an Ethernet port you have
connected to the switch port. The settings of the Ethernet port and the switch
port must match.
Cables
Shielded and non-shielded twisted-pair 10/100Base-T cables with D-coded M12
connectors are supported. The maximum cable length (without repeaters or
fiber) is 100 m (323 ft). However, in an industrial application, cable length
should be kept to a minimum.
EtherNet/IP Connections
TCP/IP is the mechanism used to transport Ethernet messages. On top of TCP,
the EtherNet/IP protocol is required to establish sessions and to send MSG
commands. Connections can be initiated by either a client program (RSLinx
application) or a processor.
The client program or processor must first establish a connection to the
ArmorBlock module to enable the ArmorBlock module to receive solicited
messages from a client program or processor.
IMPORTANT
The ArmorBlock module contains two 10/100Base-T, M12-D (4-
pin) Ethernet connectors which connect to standard Ethernet
hubs or switches via RJ-45 (8-pin) twisted-pair straight-through
cable. It can also connect to another ArmorBlock module via a
four wire twisted pair straight-through or cross-over cable. To
access other Ethernet mediums, use 10/100Base-T media
converters or Ethernet hubs or switches that can be connected
together via fiber, thin-wire, or thick-wire coaxial cables, or any
other physical media commercially available with Ethernet hubs
or switches.
