Data Output After Measurements - Omron FQ2-S/CH Series User Manual

No-protocol (TCP) Communications, No-protocol (UDP) Communications, No-protocol (FINS/
TCP) Communications
Communications commands are sent to the Sensor through sequence control in the PLC. An external device
and the Sensor communicate through no-protocol communications.

Data Output after Measurements

After a Single Measurement or Start Continuous Measurements command is executed, the Sensor
automatically outputs the data that corresponds to the measurements that have been specified as output items
to the PLC. This allows you to easily pass measurement results data from the inspection items to the PLC. You
can also choose to output only when the PLC meets the conditions that are required to receive the data (i.e.,
when handshaking is turned ON).
The output destination for data depends on the protocol that is used to communicate between the external
device and the Sensor, as described below.
PLC Link, EtherNet/IP, or PROFINET
The output data is automatically output to the following area that is specified PLC I/O memory.
Area of Memory Used for Data Output after Measurement
Data Output Area The output data for the measurement is written to this area by the Sensor after execution of the
measurement.

Flow of Communications between the PLC and the Sensor
The data to output after measurement and the PLC I/O memory area (Data Output Area) to store that data are
specified in advance. (
(1) Measurement is executed.
(2) After a measurement is executed, the specified measurement data is stored in the Data Output Area in
the PLC.
Parallel
A Parallel Interface Sensor Data Unit can be installed to enable data output.
The output data is output to the PLC signal wires via the D signals (D0 to D15).
This is only supported on the FQ2-S4/CH series.
No-protocol (TCP) Communications, No-protocol (UDP) Communications
The output data is output to the PLC reception buffer through non-procedure (normal) communications.
