Communicating with the GT-70A series
Reading an output from a sensor amplifier
Available outputs: HIGH, LOW, and GO
Device assignments: "Output" (page 3-9)
This example reads the HIGH output from the sensor amplifier of ID01.
It assumes that the operating mode assigned to the device is 3-ou tput mode.
(1)The output from the sensor amplifier is brought into the IN area by I/O
communication.
Entering an external input into a sensor amplifier
Available external inputs: PRESET, TIMING, RESET
Device assignments: "External input" (page 3-11)
This example illustrates how to enter a TIMING input into the sensor amplifier of ID01.
It assumes that the operating mode assigned to the device is 3-ou tput mode.
(1) The device va lue in the OUT area which is assigned an external input reques t is
linked via I/O communication, so that the external input of the sensor amplifier is
turned on or off.
(2)The input status of the sensor amplifier can be checked with the external input
response.
When using the TIMING input, set the "timing type" of the sensor
amplifier to "external timing input." Also, set the "input (pink/purple
wire) function selection 2" to "bank B."
