Why choose Active Ethernet I/O?
Peer-to-peer I/O for lower costs
Reduction in cable costs with input-to-output communication over
peer-to-peer Ethernet connection
Signal distribution to multiple locations with no need for PCs, PLCs,
or programming
Signal extension over existing Ethernet infrastructures for areas
where physical wiring is difficult
TFTP for automatic configuration or remote mass deployment

Active vs. Passive Ethernet I/O
Two types of Ethernet I/O are currently available. Traditional PC-based Ethernet I/O can be considered “passive” Ethernet I/O, where I/O devices cannot
operate without instruction from a PC. Active Ethernet I/O, on the other hand, is based on self-directed operation of I/O devices for automated status
reporting and simple local control.
Passive Ethernet I/O: Slower response, higher network overhead
In passive Ethernet I/O systems, a host computer obtains data from I/O devices by constantly scanning each device. For LAN environments, obtaining
real-time I/O data is possible only when devices are scanned very frequently. However, frequent scanning over the network results in high network
overhead.
When I/O points are distributed throughout remote locations, response times cannot be guaranteed. This is a challenging situation for programmers
when an application demands accurate device timing or instantaneous readings. Typically, the only option for passive Ethernet systems is to install
additional local host computers near I/O devices as needed. The local hosts collect I/O data and forward it to a central host computer for actual
processing.

TFTP Support
Store and Copy settings for mass deployment using TFTP or Windows
utility The Active Ethernet I/O server’s configuration, including IP
address, I/O configuration, and Click&Go logic can be exported to a file
using TFTP or the ioAdmin Windows utility.
You may store the exported file on the computer. When you need to
copy the same configuration to another Active Ethernet I/O server
on the IP-based network, you may use TFTP or ioAdmin to copy the
settings.
TFTP is a simplified FTP protocol that is built into Windows and Linux
operating systems. You can use TFTP with a batch file or system
shell script to establish an automatic system for upgrading a device’s
configuration.
