Entering an external input into a sensor amplifier
Available external inputs: External inputs 1 - 4
Device assignments:
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-output mode.
(1) The device value in the OUT area which is assigned an external input request 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.
• An "amplifier unit external input ON" status is recognized when
either the "external input from communication" or the "amplifier
unit input signal line" is ON, and input operation is executed (OR
operation).
[Example] When a "laser beam stop input" setting is specified at
external input "n", the "laser beam stop" input is exe-
cuted when either the "external input from communica-
tion" or the "amplifier unit input signal line" is ON.
• When bank switching is used, the amplifier unit's "BANK switching
method" must be specified as "external input switching".
