Hi, I am aiqbal, relatively new in FF bus area.
I am looking for a free tool that help calculate segment voltage
drops, performs some basic calculations for sizing power supply.
I tried the link on www.iac.honeywell.com/ichome ... provided by
Stephen ,but it never worked.
I apprecaite any help

Most suppliers make one, though they tend to be specific to their own products. We have one, of course, which does an excellent job of the complexities of our split-architecture I.S. solution. The way to make a calculator really useful is to include a database of FF devices with their current demand plus a database of FF cables by manufacturer with their parameters, but this is always going to be too much work for a vendor freebie. In reality, all the software aids on the physical layer are various ways to smarten up the presentation of Ohm's law. Perhaps the Foundation should start a project to make the ultimate Segment Calculator.....

Making one out of Excel is easy; getting the data for your application shouldn't be that hard. Take your power conditioner starting voltage, and deduct all of the voltage losses resulting from your total segment current (add up all the devices or use 20mA/device as an average):
- source voltage loss (typically 0.5V from the open-circuit voltage, non-IS)
- cable voltage loss (total segment current x cable resistance/m x length)
- spur protector loss (typically 1.0V).
= what's left for your devices (most users require 10V to allow a 1V margin over the basic device requirement).

What would be useful is a way to properly calculate the macro-cycle impact of various control schemes, but most DCS companies seem to regard that as confidential information.

. . . about 4 items down is the wiring calculation tool.

Pepperl + Fuchs has recently released V 1.4 of the Segment Checker software. Segment Checker is an open software tool that supports centralized and distributed fieldbus architecture concepts for both FOUNDATION Fieldbus and PROFIBUS PA. Segment Checker allows you to build, validate,edit and save multiple fieldbus projects and importField devices from a library or create new ones with the device editor, including generic power supplies. You can also checkoperational parameters to validate fieldbus segment architecture and evaluate potential problems with a fieldbus segment configuration.
