Automation hardware & software design

One size certainly does not fit all. That’s why we’ve designed our very own patented control panel suites and automation architecture to suit you. We prefer to exceed expectations by providing a first-class product with all the added extras, as standard. This provides you with choice, and the ability to fully utilise these components now, or in the future.

We use a range of manufacturers (including Mitsubishi, Allen Bradley, and our preferred Siemens S7-Automation platform) based on HOT standby arrangement, in some cases, for data protection and N+1 redundancy. Our touch screen technology is easy to use, ensuring that your staff can operate efficiently, saving time and money, focusing on the job at hand.

In fact, our TFT touch screen industrial PC (IPC) interfaces allow for easy use in all situations. Rack-mounted Power Supply Units (PSU) are protected via Uninterruptible Power Supplies (UPS) for a minimum of two hours data logging in the event of a power failure. The system also contains load management logic for efficient generator operation.

We’ve thought of everything, so you don’t have to.

How we do it

To fully understand why our industrial refrigeration is so popular, here’s a breakdown of some the important features found in our hardware and software.

SCADA

For our standard SCADA system, we use Siemens IPC industrial PC, built to our specifications and installed with IFIX policy – it’s the chosen platform for all of our control systems.

Automation Systems

Our automation system has been designed to have two network protocols: Ethernet, and Profibus. The Profibus protocol has four nodes, which are incorporated in our system based on Siemens S7-1500 series platform.

The central automation node controls and monitor compressor(s) via binary code signals transmitted from the central processor. The information shared between the compressor node(s) and central system will be used for data monitoring and compressor start-stop and capacity regulation and fault signalling.

The Profibus network is utilised as a subnetwork to the ethernet protocol design for data transfer between the common control’s processor and possible SCADA, or factory uplink for the future, if required.

The industrial ethernet, 100mb full duplex protocol, has been designed and selected for the communication link between the common control section and one IPC interface.

Whereas the ethernet protocol can be used for a SCADA system based on a fully graphical system display, real time data monitoring, set-point review, set point changing functionality, alarm logging, alarm historical logging and temperature data logging for diagnostics.

Automation Design

Our JD Industrial standard has been designed to ensure that the electrical automation system minimises the potential of single point of failure. For example, if network communications are lost to any processor on the sub networks, the local processors will operate via control commands and control set points.
