Introduction

In this example the fault output from an HS35iQ encoder was connected to a Rockwell PLC. A simple single line

of ladder logic was used to read the fault line from the encoder and turn on an LED when a fault is present. The

LED is just an easy way to indicate the fault was successfully read from the encoder but other solutions such as

alerting maintenance are possible by utilizing the fault output function.

Hardware Setup

The following components were used to test this example:

•

HS35iQPROGR81721R2 encoder with 2.2k load resistors

•

L27ERM-QBFC1B PLC

•

24V DC Power supply

•

LED with current limiting resistor

The supply terminals for the PLC and the encoder were both connected to the same 24V DC power supply. The

24V power supply was also connected to the +V and COM0 connections on the "DC OUT" port included with the

PLC. The anode or positive side of the LED had a resistor connected in series to limit the current supplied from

the PLC output. The LED/resistor pair was connected to DC OUT 08 and COM. The fault output from the encoder

was connected to DC IN 00. COM0 of "DC IN" was also tied to common (COM) of the PLC and encoder. See

the wiring diagram in Figure 1.
