About Connecting with External Devices
With the FZ3, serial interfaces and parallel interfaces can be used to communicate with external devices.
With serial interfaces, RS-232C/RS-422 and Ethernet can be selected as communication
ports.Non-procedure and PLC Link can be used with either communication port.
Additionally, data transfer through FTP is also possible with Ethernet.
Protocols usable with serial interface

PLC Link
With a parallel interface, control such as measurement control, scene group switching, scene switching,
clearing areas, clearing measurement values, clearing parallel terminals is possible.

About Connecting with External Devices
Controls the FZ3 through commands from a PC or specialized device.
Control from the PLC is also possible.
The FZ3 is controlled and measurement results are acquired only through data memory operations
in the PLC.
The FZ3 reads commands in the data memory (DM) and channel I/O (CIO) in the PLC, executes
measurement, and writes execution results to the data memory.
This protocol is appropriate when the PLC is used as an external device.
The PLC supported by the FZ3 PLC Link protocol is the SYSMAC CS/CJ/CP/One series PLC from
OMRON.
