Entering an external input into a sensor amplifier

Available external inputs: PRESET, TIMING, RESET, ERROR CLEAR

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-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."
