Communicating with IG Series
Entering an external input to a sensor amplifier
Available external inputs: Zero shift, timing, reset, standard waveform, laser emission
stop
Device assignments: "External Input (5 Words (10 Bytes)) assembly instance
(Instance ID): 65H" (Page 3-15)
This example shows how to enter a TIMING input 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 input signal line from cyclic communication is ON,
the sensor amplifier recognizes that the external input is ON and executes
timing input or laser transmission stop input.
