Parallel Output of Measurement Data (Only Supported on the FQ2-S3/S4/CH Series)
When a Parallel Interface Sensor Data Unit is connected to the Sensor, the two types of data output below can
be performed, in addition to output of measurement judgement results.
Output data type
Parallel Data Output
Parallel Judgement Output
Order of Parallel Data Output
Parallel Output of Multiple Items
Items set to output numbers 0 to 31 of parallel data output are output by item (4 bytes) in ascending order to
the reception buffer of the PLC. The GATE signal turns OFF > ON
When this occurs, the first data item that was output to the PLC reception buffer (data 0) is overwritten by the
next output data item (data 1).
Therefore, the data output to the PLC reception buffer must be saved to PLC memory each time the GATE
signal turns ON for each data item.
Parallel data output
0. Measurement data 0
31. Measurement data 31
*1: The operation of the DSA signal depends on whether handshaking for output control is enabled.

Data Output Timing
Output Sequence
If both parallel judgement output and parallel data output are performed at the same time, parallel judgement
output will be performed first followed by parallel data output.
Example: Parallel Judgement Output of D0 to D15 and Parallel Data Output of Data 0
Parallel judgement
D0
output D0
Parallel judgement
D1
output D1
Parallel judgement
D15
output D15
FQ2-S/CH User's Manual
for Communications Settings
The measurement data is output. A maximum of 32 items can be output.
The judgement results are output. A maximum of 16 judgement result items can be
output. The following two types of judgement results can be output:
• Judgement results for specified inspection items
• Judgement results of set judgement conditions for the specified item values
