Supporting Legacy Embedded Systems

One request we get quite often at Impulse, is whether we can support older, legacy applications. There are typically a few reasons why legacy systems can't be simply upgraded to the latest hardware technologies: the software was written in a particular programing language or for a particular operating system platform, the original source code has been lost or the developer is no longer in business, which can make migrating the application to a new platform and operating system cost prohibitive or even impossible for the customer to achieve, or it could be that there is bespoke hardware such ISA and PCI interface cards or serial interfaces which for similar reasons can’t be changed. Whatever the scenario, Impulse Embedded in most cases can provide a solution that will not only get you through the initial stages of such a scenario but could support you for years to come, saving large amounts of time and re-development expenditure.
Impulse partners with key global IPC manufacturers who specialise in providing hardware support for legacy systems, processing architectures and interfaces. This, combined with our in-house Embedded Systems Specialists who have decades of experience providing support and advice to OEMs and system integrators in the Embedded market, enables us to not only to support our customers' embedded computing products and applications through suitable computing and operating system platforms, but it also gives our customers the option to integrate serial, Fieldbus, analog and digital I/O technologies with modern enterprise and cloud platforms such as AWS and Azure.

Embedded Computer Systems considerations

In order to begin the process of supporting or modernising a legacy embedded system, we first look at the original processor platform and operating system so we can tailor the replacement solution to be as close to the original as possible.

One of the options we often look towards is the Vortex86 range of single-board computers from Icop Technology. The Vortex86 CPU's are 32-bit x86 computer processors that offer clock frequencies from 300MHz to 1GHz and support DOS, older Windows operating systems (desktop, embedded and CE/Compact), as well as Linux, and have built-in support for a range of modern and legacy I/O interfaces such as ISA, PCI, PCIe, serial comms (RS-232 and RS-485), IDE/SATA, I2C, SPI, CAN, GPIO, USB and 10/100 LAN.  Icop's sister company DM&P Electronics, manufacture the chip in-house allowing for very long supply and support lifecycles across their product range making them ideal for long-term applied computing applications where base system continuity is key.

In addition to the Vortex range, we can also supply base boards and systems that support all major available Intel platforms from Atom to Core and everything in-between, supporting ISA, PCI, PCIe, serial (RS-232 and RS-485), SATA/RAID, CAN, GPIO and USB.

Next, we look at the board footprint. With all of the major embedded footprints at our disposal, such as PC/104, 2.5”, 3.5”, Pico-ITX, plug-in options such as half-size ISA and PCI, full-size PICMG 1.0/1.3 SBC's as well as Mini-ITX, ATX and Micro-ATX industrial motherboards we are able to source the exact board platform to meet the requirement of your legacy embedded system.

Finally, we consider the environmental variables such as power, temperature and IP rating of the device. Not only do many of our products support wide voltage input off-the-shelf, but Impulse can also provide a range of power conversion products to tailor the incoming power from your installation to an embedded computing device, as well as UPS solutions if power stability is an issue.

As well as devices that work in standard temperature environments (0°C to 50°C) we can also offer the vast majority of our solutions to cope with wide temperatures as low as -20°C and as high as +70°C. Some of our solutions even reach extended operating temperatures as low as -40°C and as high as +85°C.

Using the available technologies, Impulse has supported customers with maintaining legacy applications in all kinds of environments such as roadside controllers and signage, OEM medical devices, automation systems, test and measurement devices amongst many others.
 

Legacy serial and I/O solutions

In addition to our industrial and embedded computing offerings, should your application use serial-based communication Impulse offers an extensive range of Serial Servers, Fieldbus gateways, distributed I/O devices and IIoT gateway products to bring valuable data from your PLCs and sensors to a modern IP network or even the cloud.

This could be as simple as connecting a serial port on a CNC machine to an IP network and being able to then send jobs directly to the machine from the design office, or it could be more complex as taking numerous serial or serial Fieldbus devices (Modbus/RTU, DNP3, Profibus etc.) together with anti-log and digital I/O points from PLCs, drives, meters etc., and making them available on an IP network so that they are available to SCADA systems, data collection servers and even cloud systems.

In conclusion 

Whatever the make-up of your application, and its age, it’s worth talking to our Embedded Systems Specialists before completely overhauling older, but still very functional systems and applications, as it is very possible we can provide you with a solution to maintain or modernise your legacy computing and communications installations without the outlay of completely replacing your hardware.
