Demo22 provides the following functions:
Provides a configuration file for system configuration
Based on configuration file, performs data acquisition when the timer is up
Based on configuration file, performs data averaging
Based on configuration file, performs digital filtering (slew-rate control)
Based on configuration file, performs data compression
With the help of Xsever (demo22), one PC can link to multiple 7188E2
modules. In turn, every 7188E2 can link to multiple 7000 modules. PC need
only send one TCP/IP command to the 7188E2, then the 7188E2 will send
back all I/O points installed in the RS-485 network. Therefore, the PC sends
one TCP/IP packet to read back hundreds of I/O points installed in the 7188E2.
This Lets one PC controls thousands of I/O points easily.
