Allen-Bradley PLC programming in Kenya: ControlLogix, CompactLogix, Micro800 and MicroLogix

Allen-Bradley controllers from Rockwell Automation are common on imported bottling, packaging and process lines. We program and troubleshoot Logix and Micro800 controllers, and migrate discontinued SLC 500 and MicroLogix systems to current hardware.

Allen-Bradley PLCs we work on

• ControlLogix: large plants and process control
• CompactLogix: mid-size machines and lines
• Micro800 (Micro820, Micro850, Micro870): standalone machines
• MicroLogix and SLC 500: legacy controllers we maintain and migrate

Software: Studio 5000 Logix Designer, RSLogix 5000, RSLogix 500, Connected Components Workbench. Networks: EtherNet/IP, DeviceNet and DH+ on older systems, Modbus to third-party devices.

Allen-Bradley PLC services

• Ladder, structured text and function block programs in Studio 5000
• Clearing major and minor faults, I/O faults and EtherNet/IP connection problems
• SLC 500 and MicroLogix to CompactLogix or Micro800 migration
• Add-on instructions and structured tags for clean, reusable code

Signs your PLC system needs attention

• The machine stops with faults nobody can explain, or the only person who understood the program has left
• There is no current backup of the program, or the backup does not match what is running
• Spare CPUs and I/O cards are discontinued, expensive or months away
• Operators work around the sequence by hand because the logic no longer matches the process
• You want production data, remote access or new functions that the old program cannot provide

How we approach a PLC job

1. Upload and back up the running program and hardware configuration before any change.
2. Document the I/O and the sequence with your operators, so everyone agrees what the machine must do.
3. Write or modify the logic offline, structured and commented, and test it with simulation where possible.
4. Commission on site: test every input, output, interlock and alarm, then run under real production load.
5. Hand over the final program, I/O list and drawings, and train your technicians on fault finding.

Tips from our engineers

Keep the right Studio 5000 version

Logix projects open only with the matching major firmware revision. Keeping the right software version available saves hours on service calls.

Migrate discontinued controllers in a plan

SLC 500 and most MicroLogix controllers are discontinued. Converting the logic and testing it offline keeps the shutdown short.
