Entering an external input to a sensor amplifier
Available external inputs: External input 1, External input 2, External input 3, External
input 4
Device assignments: "External Input (5 Words (10 Bytes)) assembly instance
(Instance ID): 65H" (Page 3-16)
This example shows how to enter external input 2 to the sensor amplifier ID01.
(1)The device value in the OUT area to which an external input request was
assigned is linked via cyclic communication and the external input of the sensor
amplifier is turned on or off.
(2)You can check the input status of the sensor amplifier with the external input
response.
• If the external input or sensor amplifier input signal line from cyclic
communication is ON, the sensor amplifier recognizes that the external
input is ON and executes input operation (OR operation). For example, if
the external input or sensor amplifier input signal line from cyclic
communication is ON when laser transmission stop input is assigned to
external input n, laser transmission stop input is executed.
• To use bank switching, set "bank switching method" to "external input
switching".
