1756-EWEB Module: Web Server and More
In this lab we will explore the 1756-EWEB module. You are calling on your favorite
OEM, the Acme Tool and Machine Company (Acme). The machines that Acme
builds are systems of three or four different complex stations, each in line and tied to
the others, so that one station feeds the next. Acme’s machines are all of the same
general design, but each order Acme receives for a machine does have some
customization required. Acme nearly always starts with a ControlLogix system with
only a few modules of local I/O. The majority of I/O is Point I/O on ControlNet.
Every machine also has at least one PanelView on ControlNet. Acme brings up a
number of issues that they have been discussing with their customers, who are end
users.
1. Acme’s customers have been demanding better support from Acme;
2. Acme needs a better way to keep their machine documentation up to date for their
customers (this includes machine user manuals, maintenance schedules, service
manuals, troubleshooting documents, etc);
3. End user customers want to integrate data from Acme’s machines into their
business systems. End user customers in Acme’s industries tend to use main frames to
create production orders, collect data, generate reports, etc.
4. Acme always puts their I/O on ControlNet, so customers have always needed to
buy either a ControlNet card for their programming computer, or a 1756-ENBT for
their ControlLogix chassis. In either case, customers have not been happy having to
buy an extra module just for the sake of programming.
In this lab, we will see how the 1756-EWEB will help Acme to meet these demands
from their customers.
