A = Power/status indicator – indicates power applied to module and

status of module.

B = Insertable label for writing individual I/O assignments.

C = Status Indicators –

A = Status of input A

B = Status of input B

Z = Status of input Z

G = Status of input G

+ = Positive count detected

– = Negative count detected

+ Yellow On when a positive pulse is detected; turns off

on negative pulse.

- Yellow On when a negative pulse is detected; turns off

on positive pulse.

OK Red Red during initialization after power turned on

Green Green when initialization is completed

In this chapter, we told you how to install your incrementa encoder

module in an existing programmable controller system and how to
