2-1 Controlling Operation and Outputting Data with the Sensor's Standard Parallel Connection
This section explains how to directly connect the Sensor to external devices with the I/O cable, and control the
Sensor and execute output.
Basic Operation with a Parallel Connection
This section describes the basic connections and signal flow with external devices.
With the default settings, the Sensor operates in the following manner.
*1: You can also use the READY signal, which will turn ON when a measurement trigger can be input.
You can assign the READY signal to any output from OUT0 to OUT2.
( Getting Individual Judgements and Expression Judgements: p. 41)
• Create the ladder program to control the TRIG and IN5 input signals so that they do not turn ON while the BUSY
signal is ON. If not, a TRIG input error will occur and the ERROR signal will turn ON.
• Operation When the Sensor Power Supply Is Turned ON
The BUSY signal will operate as shown below when the Sensor’s power supply is turned ON.
Create the ladder program in the PLC or other external device so that the BUSY signal is ignored while it turns OFF,
ON, and OFF again for up to 5 s after the power supply is turned ON.
