PLC & HMI Programming

Crown Controls provides PLC and HMI programming for new machinery, conveyor systems, standalone cells and changes to existing equipment.

We work across multiple platforms, including Allen-Bradley, Siemens STEP 7 and TIA Portal, Omron and Schneider. Based in Charlestown, Co. Mayo, we undertake programming, integration and commissioning projects across Ireland.

PLC Programming & Control Systems

We develop control software around the equipment, the process and the people operating it, with clear operating sequences and software that can be maintained and extended.

  • New PLC programs for machinery and process equipment.
  • Automatic sequences, manual controls and operating modes.
  • Conveyor sequencing and coordination between machines.
  • Pump, valve, motor and variable-speed drive control.
  • Instrumentation integration and process control.
  • Alarm handling, fault information and recovery sequences.
  • Changes and additions to existing PLC software.

We work with manufacturers, machine builders, equipment suppliers and contractors, from the initial operating requirements through to commissioned equipment.

PLC Platforms & Programming Software

We provide PLC and HMI programming across multiple manufacturers, including Allen-Bradley / Rockwell Automation, Siemens, Omron and Schneider Electric. Our Siemens work includes SIMATIC STEP 7 and TIA Portal for S7-300, S7-400, S7-1200 and S7-1500 systems. We also work with CompactLogix, ControlLogix, SLC 500, MicroLogix and Schneider Modicon controllers.

HMI Development & Replacement

We develop operator interfaces that make equipment status clear and give operators the controls and information they need to run the process and respond to faults.

Applications bring together machine and process overviews, operating modes, settings, alarms and diagnostics. Where required, we include trends, production values, recipes and product changeover settings, with appropriate access for operators and maintenance personnel.

We also modify existing HMI applications and replace older operator panels, including PanelView interfaces, adapting the screens and communications to suit the replacement hardware.

Equipment Integration & SCADA

We connect PLCs with drives, remote I/O, sensors, instrumentation and other machines, bringing individual devices together into a coordinated control system.

For applications requiring wider visibility, we develop and integrate SCADA systems, including Ignition, to bring equipment status, alarms and process information into a central interface. This can cover a standalone production cell, multiple machines or separate process areas, with monitoring and control arranged around how the installation is operated.

Changes & Upgrades to Existing Systems

We modify PLC and HMI software for additional conveyors, new equipment, revised sequences, replacement drives and expanded instrumentation. We also support controller and HMI replacements where hardware has become obsolete or difficult to maintain.

Before making changes, we review the existing application, establish the available software and drawings, and take backups. The modifications and commissioning arrangements are agreed around the equipment and production schedule, with ongoing technical support available afterwards.

Discuss Your Programming Requirements

Contact Crown Controls about a new control program, an HMI application or changes to an existing installation.

Tell us the PLC and HMI make and model, the work required, the site location and your preferred timescale. Existing software files and drawings are helpful, but you can contact us before these are available.
