Before Internet (B.I.), traditional device use RS232 output port to

communicate with PC

Drawbacks of serial communication

Advantage of TCP/IP

After Internet (A.I.), traditional device with RS232 output need a PC to

connect to Internet,

until the invention of LinkServer

Various output protocols• Device with Analog output

To be used within LinkServer environment

• For Device with Analog output– Require 3 converters:

AI->RS485->RS232->TCP/IP

• For Device with RS485 output– Require 2 converters

RS485->RS232->TCP/IP

• For Device with RS232 output– Require only 1 converter

Conclusions

• Sensors and Devices can be integrated through FS and LS and accessed through Internet with only 1 fixed IP.

• FS and LS can be integrated to establish SA or MA (Multi-Agent) Supervisory or Distributed Control and Data/Image Acquisition System.
