Why Xserver Technology?
Ethernet is extremely popular, so you can find it nearly everywhere. For
industry applications, there are some important issues that are given as follows:
Linking RS232 devices to Ethernet network
Reading analog/digital input signals from Ethernet network
Sending analog/digital output control to Ethernet network
Standing alone operation
True distributed computation.
Working stably and reliably as PLC
Easy programming and maintenance
The Xserver is designed to solve all the above problems
1 Linking RS232 devices to Ethernet network
The Xserver provides port 10000 for serial port configuration and port
10001 to 10008 for data sending/receiving. So its built-in function is to
link RS-232 devices.
2 Reading
analog/digital
input
signals from Ethernet network
3 Sending analog/digital output control to Ethernet network
The Xserver supports easy interface to the 7000 family. So its basic
function is to link to 7000 family for analog/digital I/O. The Xserver also
support an I/O expansion bus for user’s special devices.
4 Standing
alone
operation.
5 True distributed computation.
The Xserver supports a loop-scan function and a timer trigger function to
assist Xserver in data acquistition, data analysis and performing immediate,
real-time control. The event-trigger function makes Xserver send a TCP/IP
packet to destination immediately when an emergency is occurred. In
general, Xserver can make the 7188E/8000E work perfectly for both data
acquisition and control application.
6 Working stably and reliably as PLC
The most important codes of Xserver are provided by ICPDAS. We have
spent thousands of hours designing and testing this server. Consequently,
this server is as stable as PLC without any user’s additional programs. If
users add their tailor made additions, the dual-watchdog mechanism and
well-designed user interface will make this new Xserver stable enough for
