Communicating with the IB Series

Entering an external input into a sensor amplifier

Available external inputs: External inputs 1 - 4

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.

• 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".
