modules on different serial ports may have the same address. Every
module on one serial port of a host computer must have the same
baud rate.
Figure 6. Address and Baud Rate Switch
Switches 1-5 set the network address of the FP-1001. The
addresses of the terminal bases connected to the network module
are automatically configured to be sequentially higher than the
network module’s address. For example, if the network module is
set to address 20, the I/O module in the terminal base immediately
connected the network module is at address 21, the next I/O
module is at address 22, and so on. A terminal base is assigned a
network address whether an I/O module is inserted into it or not.
Table 1 shows the possible switch positions and the corresponding
address of the FP-1001.
