Communicating with an External Device
Overview
Command frames are sent to the Sensor and response
frames are received from the Sensor without the use of
any specific protocol.
Data can be exchanged between the PLC, computer, or
other external device and the Sensor by sending and
receiving ASCII or binary format data.
Control and Output in No-Protocol (TCP) / No-Proto-
col (UDP): p.173
Commands or inspect item parameters are transfered or
received between Sensor Data Unit and or RS-232C
cables in No-protocol communication.
Introduction to RS-232C Connections: p.202
This is a command system (FINS) for message services
that can be used in common on OMRON networks. Data
can be exchanged between an OMRON PLC and the
Sensor by a command/response method.
