Automation Control Panels and System Retrofits

Panel work starts with the machine or plant equipment list. We consider connections between motors, drives, sensors and control hardware within the electrical design. At this stage, we define which equipment the panel will control and which information it will receive from the field.

PLC, operator panel and drive connections are assessed alongside the production sequence. We assemble the control panel according to these connections. Sharing existing equipment details and the expected functions of the new system during design allows hardware and field connections to be planned together.

Before a retrofit, we examine the internal panel layout, control hardware, electrical drawings and field equipment. We identify the connections to be changed by assessing how the new control system relates to existing equipment. Panel photographs, device details and existing drawings help with the initial review.

For fault investigations, screen upgrades or added equipment, we describe the required tasks individually. Hardware to be changed in the panel, circuits to be rewired and software functions to be modified are specified in the quotation. The business can therefore assess which parts the retrofit will affect.

• Automation panel and cable checks.
• Reviewing existing connections alongside electrical drawings.
• Defining panel upgrade and rewiring scope.

We convert relay control systems to PLC and HMI control. We assess the machine's existing sequence, operator controls and field connections, then engineer the new control hardware accordingly. Required modifications to panel and field connections are also part of the conversion scope.

PLC software and HMI screens work together with panel hardware. During a retrofit, the control functions and screens to be upgraded are defined alongside hardware changes. The detailed scope of software development and operator screens is covered separately in our PLC and HMI service.

After panel assembly or retrofit, we carry out cable checks and system testing. On site, we assess transfer of sensor information to the control system, motor and drive commands and equipment operating sequences. Checks are based on the equipment and functions defined in the project.

For changes to existing production, we discuss the shutdown that can be planned for implementation and commissioning at the outset. Operating conditions, site access and existing system information supplied by the business help prepare the implementation plan.

Electrical drawings, PLC/HMI program backups, an operating manual and operator training are included in our standard handover. Training covers use of the upgraded control system and operator screens. For technical service, we connect through the customer's computer or a remote access device when the customer provides internet access.

What information is needed for an automation panel quotation?

Share the function, equipment list and location of the machine or plant and the work you require. For existing systems, panel photographs, PLC/HMI and drive details, electrical drawings and any planned production shutdown help with the assessment.

Can a retrofit use the existing panel?

The retrofit scope is defined after examining the condition of the existing panel, control hardware and field connections. The assessment describes the equipment to retain, parts to replace and wiring work together.
