2.2 Ethernet I/O Applications
The 7188E series provide 3 types of Ethernet I/O solutions. They are as follows:
1. Link to 7000 series modules
2. Install an available X??? into I/O expansion bus.
3. User designs a special design X??? and install it onto the I/O expansion bus
2.2.1 Link to 7000 series modules
The 7000 series modules provide a variety of I/O operations, for example,
D/I, D/O, A/D, D/A, Counter and Frequency Measurement. The 7000 series
was originally designed for the RS-485 network. Therefore, COM2 of 7188E
family is designed to link to 7000 family.
Using VxComm technology, old programs in PC can be upgraded from
RS-485 network to Ethernet network without any program modification. Refer
to Sec 2.1.1 for more information.
Using Xserver technology, the client program in PC can send TCP/IP
packets to 7188E. The data in the TCP/IP packets can be converted to RS-485
commands and sent to the 7000 family. Also, the response from RS-485
network will be converted to TCP/IP packets and sent back to the client
program in PC.
2.2.2 Install one X??? board onto I/O expansion bus
Refer to “I/O Expansion Bus for 7188X/7188E series User’s Manual
(Volume 1)” and “I/O Expansion Bus for 7188X/7188E series User’s Manual
(Volume 2)”, and users will find many X??? boards that are already and
available for various I/O operations. Users can find one expansion board to fit
their requirements. Or they can send mail to
to request
new specifications. We won’t guarantee that we will design it immediately, but
if the specifications are well-designed and perhaps needed by other users, we
will design it as a standard X??? board.
