further cabinets are added in response to post-installation changes. Clearly, it is time for a new solution that facilitates a standard design for all marshalling requirements, that is compact and space-saving, while at the same time is simple to install and maintain. Furthermore, any new marshalling solution should be easy to reconfigure and have minimal impact on project and whole life cost.
SMART UNIVERSAL MARSHALLING
Eaton has applied its industry knowledge and technical expertise to develop a new solution that offers the simplification and standardisation that customers are seeking, with no compromise on functionality. Smart Universal Marshalling (SUM) is a modular approach that enables the five key marshalling requirements to be achieved using a single cabinet design. Eaton calls its solution MTL SUM5. Benefits for process engineers are considerable. Firstly, all the marshalling functions are in one unit, so there is no longer any requirement for complex, hard-wired interconnections – eliminating the risk, downtime and associated costs that arise from wiring faults. Te configurable design accommodates late changes, reducing risk during project execution. It also ensures that the system is adaptable over time, without major rewiring or the need for cumbersome ‘bolt-on’ equipment.
SUM typically reduces the number of marshalling components by 65% compared to a standard solution. For example, on a project with 4,500 I/O small changes in the number of each I/O type results in the Bill of Materials for the traditional solution required 4,651 changes. Te Bill of Materials for the same project using MTL SUM5 would require only 115 changes. Te modular

types mean fewer spare parts need to be held in stock. With MTL SUM5, configuration information is held in the terminal, so a module can be changed out without the need for reprogramming. Te modular design approach eliminates some components altogether and makes others more compact, so there is typically a 30-50% saving in the number of marshalling cabinets required. Tis in turn means there is potential to reduce the overall size of control rooms – freeing more room for production.
IN SUMMARY SUM addresses concerns regarding the costs and complexities associated with traditional marshalling systems. It makes life easier for busy process engineers by significantly reducing the number of components required and totally eliminates the need for complex wiring. Tis in turn delivers advantages that include a reduced Bill of Materials, simplified installation and maintenance, and the ability to adapt rapidly to change. In short, it makes marshalling fit for purpose in an automated, connected world.
