6.3 PC Networking Applications:
(For this application, we recommend to use i-7520U to replace the i-7520)
Every remote-PC must have a unique address. This unique address is similar to
the module address of the 7000 series. We call it a “slave-PC address”. The module
address of the 7000 series is limited to 256, but the slave-PC address is unlimited. The
user can connect thousands of PCs in one RS-485 network by using a repeater, the
7510.
Refer to “DCON_DOS.pdf” for software details. Using this software, the host-PC
can send out commands to remote-PCs, just like sending commands to the 7000
series modules. The remote-PC will receive these commands and execute the
command if the destination addresses matches it’s local address.
These remote-PC and 7000 series modules can use the same RS-485 network.
The host-PC can send out the 7000 series commands and send out PC-networking
commands at different times. The modules and remote-PCs will receive their
command respectively. This makes the network very low cost, with high flexibility and
reliability. This unique feature is not found elsewhere in the world.
