Starting Over with a New CMS

Learning a new CMS for my two web sites. They were wiped out, along with 450 on the same server. So, I'm taking this opportunity to start over. Xaraya is not only a CMS (Content mangement system) but a Web foundation. Update: Sept 2006, Now I am using Joomla.

Lack of Standards in Modbus

I am about to teach a class on Modbus to customers. Most of our customers see computers as a tool (This is a good thing TM), and are not programmers. So I have to explain how this very old standard does not cover current use and there are dozen's of different ways to use Modbus. The basic standard has not grown since the 70's. There are no standards for bytes, 32 bits, 64 bits, floating points, bitfields. Even byte order is not followed by some vendors.
