Entering an external input into a sensor amplifier
Available external inputs: PRESET, TIMING, RESET, ERROR CLEAR
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.
• Set the simultaneous input setting of the sensor amplifiers to individ-
ual input. If it set to simultaneous input, the simultaneous input func-
tion becomes invalid or unable to handle the external input correctly.
• When using the TIMING input, set the "timing type" of the sensor
amplifier to "external timing input."
