Security Setting

Though Ethernet technology comes with great benefits in
speed and integration, there also exist risks about network invasion
from outside. For this reason, a security protection design was built into
the ADAM-5000/TCP Series. Once the user has set the password into
the ADAM-5000/ TCP firmware, important system configurations
(Network, Firmware, Pass- word) can only be changed through password
verification.

1-2-9 UDP Data Stream

Most of time, each host PC in a DA&C
system needs to regularly request the I/O devices via TCP/IP packs to
update current data. It may cause to data collision and lower
performance on the network, especially when there are frequent
communication between multi-servers and I/O devices. To reduce the
communication loading of the host computer on your Ethernet
network, the ADAM-5000/TCP Series also supports UDP
(User Datagram Protocol) protocol to broadcast the data packs to
specific IPs without requesting commands. Users can apply this
great feature to implement Data Stream, Event Trigger, and other
advanced functions.

1-2-10 Modbus Ethernet Data Gateway

Much more than an I/O system, ADAM-5000/TCP Series provides an
RS-485 network interface for other Modbus devices integration.
It works as Ethernet Data Gateway, upgrading Modbus serial network
devices up to Ethernet layer. Maximum 16 nodes of ADAM-5511 or 3'rd
party products supported Modbus protocol are allowed to integrate
with an ADAM-5000/TCP Series. This great feature enlarges your system
scope, as opposed to other general dummy I/O system.
