Allen Bradley PLC-5 Troubleshooting
Course overview
Manufacturers are increasingly facing greater pressures to reduce costs and maintain efficiency whilst also maximising output. These problems are further challenged when it comes to arranging shift patterns to release essential production line staff for training.
This problem can be eased, as we now offer you three day courses rather than our more traditional five day courses on Allen Bradley PLCs. Our new three day course enables you to maintain your efficiency levels with the minimum of disruption, whilst also providing focused learning.
This troubleshooting course targets maintenance personnel who have attended the 3 day First Line Maintenance course, or who have a reasonable working knowledge of Allen Bradley PLC-5 PLCs, and who need to be able to troubleshoot PLC-5 hardware, software and process related faults. The course is entirely practical and consists of troubleshooting a range of fault scenarios to establish a logical approach to faultfinding and to reinforce the use of standard tools and test procedures.
Target group
All engineering personnel involved with the maintenance, servicing and troubleshooting of automated systems controlled by Allen Bradley PLC-5 Systems.
Course duration
Courses run over three days.
Syllabus
Logical Approach to Faultfinding
- Understand what should be happening
- Understand what is/is not happening
- Understand the reasons why most faults will not be PLC hardware or software & are much more likely to be due to field device failures or wiring problems
- Define the symptoms & consider possible causes
- Perform appropriate checks to localise the problem
Troubleshooting Hardware Problems
- Understand the importance of carrying out visual checks
- Know the first level checks to begin to quickly distinguish between PLC & field faults
- Know typical fault symptoms for common PLC hardware failure
- Be able to recognise & interpret the meaning of system diagnostic LEDs
- Be able to interpret the status of I/O LEDs & relate these to the operation of field devices
- Understand implications of sink/source configuration when testing I/O signals
- Understand the value of module swapping when localising hardware faults
PLC-5 system Re-starts
- Understand the operational effects of cycling the key switch or power
- Understand the implications of the retentive/non-retentive instructions
- Understand the operational effects of cycling the power with a failed battery
- Understand EEPROM memory configuration & operation
Troubleshooting through interpreting Program Code
- Navigating ladder views in RSLogix 5

Recommend follow up courses
Allen Bradley PLC-5 Networked Systems
The benefit of attending this further 3 day course is that delegates will be able to gain knowledge & practical experience of maintaining & troubleshooting Allen Bradley PLC-5 control systems that incorporate DH+, RIO, Ethernet, ControlNet, DeviceNet & DH485 networks.
Understanding Allen Bradley PLC-5 Programs
The benefit of attending this further 3 day course is that delegates will be able to make sense of & understand more complex (but typical) program code so that they are able to trace field I/O & both bit & word status through data structures & more powerful routines to troubleshoot beyond just the very basic program code.
