Because I/O on Demand represents a significant shift in how most types of I/O are engineered and implemented, it can be a challenge to decide just what options to use in a particular project. And while plant practices and application requirements may dictate the mix of I/O on Demand platforms chosen, figuring out how much money you could save relative to the traditional way of doing things just got a whole lot easier.
Enter IOonDemandCalculator.com, a new website created by Emerson Process Management to help you estimate project cost savings—and impact on project schedule—based on the mix of electronically marshalled, wireless and fieldbus I/O you expect to deploy.
The essential information you'll need to know includes:
Once these essential project parameters have been entered into the calculator, you can estimate the project costs savings and the impact on delivery schedule for different mixes of I/O on Demand platform options relative to a conventionally wired and marshalled system. The essential options include electronically marshalled in a central control room, electronically marshalled in field junction boxes, fieldbus and wireless.
Take, for example, a project with a total I/O count of 5,000, 20% spare I/O capacity and average control-room-to-junction-box and junction-box-to-field-device distances of 200 m and 20 m, respectively.
If 20% of I/O are electronic marshalled in the control room, 30% are electronically marshalled in field junction boxes, 30% of I/O points are implemented using wireless and 10% using fieldbus, the I/O on Demand Calculator indicates that you stand to save $8.11 million in project costs relative to conventional wiring practices.
Further, if 500 I/O points (10% of the total) are estimated to be subject to change orders, and 100 people are working on the project, the I/O on Demand Calculator indicates that this mix of I/O on Demand platforms can potentially eliminate 44.9 man-project days and 1,867 man-hours of work.
While these initial project cost savings are nothing to sneeze at, it's important to note that they do not take into account the longer-term benefits afforded by electronic marshalling and a wireless infrastructure.
Indeed, once a project is done, the I/O on Demand savings have only just begun.
