2.2 Fiber I/O Applications

The PDS-220Fx series provides fiber optic I/O solution:
Linking to I-7000 series modules
The I-7000 series provides a variety of I/O operations, such as D/I, D/O, A/D, D/A, Counter
and Frequency Measurement, etc. The I-7000 series was originally designed to be used
with RS-485 networks, so COM2 on the PDS-220Fx can be used to link to I-7000 series
modules. They are very robust and work well under the harsh industrial environments.
By using VxComm technology, programs that on the host PC support serial devices can
be upgraded from a RS-485 network to a fiber optic network without requiring any
modifications to the program. Refer to Sec. 2.1 for more information.

2.3 Configurable Fiber Optic Data Logger

Using the VxComm driver, PDS-220Fx + I-7000 modules can be virtualized to become
COM Port + I-7000 modules located on the host-PC, and then the Data Logger in the
DCON Utility can be used to access data of I-7000 from the fiber optic. Signal data
originating from the I-7000 modules can be analyzed using MS-Excel without the need to
write any custom programs
