Communications Using the Controller I/O Cable
Using the Controller I/O Cable
By using the Controller's I/O cable, you can output the measured value or judgment result
to external devices, or input a control signal, such as zero reset or LD-OFF, from external
devices. A predetermined I/O signal is assigned to each signal wire of the I/O cable.
Assignments and Functions of I/O Signal Wires
Assignment of output signal wires
*1: In the IC lead pitch and IC lead width judgment modes, both the HIGH and LOW outputs turn ON when the
judgment result is NG.
*2: In the IC lead pitch and IC lead width judgment modes, 0 V or 4 mA is output at all times.
Cable color Function Signal Description
White Judgment
output
(*1)
HIGH Turns ON when measured value > HIGH threshold.
Green PASS Turns ON when LOW threshold
≤
measured value
≤
HIGH threshold.
Gray LOW Turns ON when measured value < LOW threshold.
Co-axial
(black) Analog output
(*2)
Outputs the analog value corresponding to the measured
value.
4 to 20 mA current or -5 to +5 V voltage can be selected.
(Select this by the current/voltage switch on the rear of the
Controller.)
Part Names and Functions p.22
With analog output, output values can be scaled or
corrected to suit the conditions of the connected external
device.
Setting analog output conditions p.68
