Output
*1: The execution of commands or other processing received through any other protocol cannot be detected.
The parallel BUSY signal can be used in all protocols.
If you use more than one protocol and need to detect command execution, use the parallel communications BUSY signal.
*2: This signal is linked to the measurement processing.
It is not associated with the BUSY signal. It is not related to the parallel interface OR signal.

Command/Response Method

Parallel
Commands are input to the Sensor by turning the IN signals (Standard Parallel: IN0 to IN5, Parallel Interface
Sensor Data Unit: IN0 to IN7) ON and OFF. There is no direct response to these commands. Confirm whether
a command was received by checking the BUSY signal.
The command code is input with part of the IN signals (Standard Parallel: IN0 to IN4, Parallel Interface Sensor
Data Unit: IN0 to IN6), and the command is executed by turning ON the execution bit (Standard Parallel: IN5,
Parallel Interface Sensor Data Unit: IN7).
Standard Parallel
IN5 IN4 through IN0
Execution Command
PLC Link, EtherNet/IP, or PROFINET
Command/response control signals can be exchanged by storing control commands from the PLC to the
Sensor and responses from the Sensor to the PLC in the I/O memory of the PLC. This enables you to send
single measurement and scene switch requests to the Sensor without any sequence control with
communications commands from the PLC.

Function
The FQ2-S/CH series turns ON
this signal when measurements
can be performed and it is in Run
Mode.
This signal tells when execution
of the DI command has been
completed.
This signal tells when Camera
exposure has been completed.
This is the trigger signal for the
strobe.
