About Connecting with External Devices

With the FZ4, 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.
Data transfer through EtherNet/IP (tag data link communication) or FTP is also possible with Ethernet.
Protocols usable with serial interface
The protocols that can be used with a serial interface are listed below.
Non-procedure
PLC link
7
With a parallel interface, control such as measurement control, scene group switching, scene switching,
clearing errors, clearing measurement values, clearing parallel terminals is possible.
Important
PLC link function refers to a function that communicates using 3 link areas indicated below: the command area,
●
response area and data output area.
It is different from the serial PLC link protocol used to inter-connect PLCs serially.

360 About Connecting with External Devices
Controls the FZ4 through commands from a PC or specialized device.
Also possible to control from the PLC.
The FZ4 is controlled and measurement results are acquired only through data memory operations
in the PLC.
The FZ4 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 is appropriate when the PLC is used as an external device.
The PLC supported by the FZ4 PLC link protocol is the SYSMAC CS/CJ/CP/One series PLC from
OMRON (models supporting FINS command) and PLC MELSEC Q series (protocol: MC protocol)
from Mitsubishi Electric Corporation.
