Troubleshooting and Corrective Actions

If the system fails to perform as expected, it may be necessary 
to perform one or more of the following procedures to discover 
the cause and restore normal operation.

  

Digital Inputs and Outputs

If a digital input or output doesn’t seem to be working, check 
the following:

•

Is the digital I/O point’s 

Direction

 set correctly as an input 

or output? See 

Digital I/O on page 132

.

•

Is the 

Logic

 set correctly? Refer to 

Digital I/O on page 132

.

•

Is the output selected as an Output Destination for more 
than one function (e.g. a control output and an alarm 
output)? See 

Channels on page 115

 and 

Alarms on page 

123

.

•

Is the digital I/O point associated with a variable set as an 
output in a logic program? Refer to the 

LogicPro User’s 

Guide

.

•

Are the cable and wiring connections correct? See 

Connecting I/O to the PPC-2010 on page 37, Connecting to 
the Relay Outputs on the PPC-206x on page 70

, and 

Connecting Digital Inputs to the PPC-207x on page 74

.

•

Is leakage current from one of the configurable I/O points 
such that a device is being switched on or partly on? See 

Connecting Digital Outputs on page 41

.

•

Is the field I/O device powered? Note digital outputs on the 
PPC-2010 and PPC-2040 sink current. That current must 
be sourced by an external device that is referenced to the 
PPC’s common. See 

Connecting Digital Outputs on page 41 

for the PPC-2010 and 

Connecting Digital Outputs on page 

65 

for the PPC-2040.

  

Process Variable

If the Process Variable is not updating, check the following:

•

Is a valid analog input selected as the 

PV Source

? See 

Channels on page 115

.

•

Is the input corresponding to the 

PV Source

 updating as 

expected? If not check LEDs on the associated module, See 
corresponding module section in this chapter.

•

Is the input wiring correct? See 

Connecting I/O to the 

PPC-2010 on page 37, Connecting Analog Inputs to the 
PPC-2021 — 2025 on page 45, Connecting Encoders and 
Analog Outputs to the PPC-2030 on page 55, or Connecting 
to the Relay Outputs on the PPC-206x on page 70
