Windmill News: Windmill's Flexibility Aids Data Logging 
from Pilot Plant
________________________________________________________

Until recently, a pilot plant for the manufacture of 
water treatment chemicals used an old DOS program to 
control its data loggers. The plant's Program Manager 
wanted to upgrade the software but feared he would have 
to write the program himself, as he could not find a 
flexible product that would accept custom-made drivers. 
Then he discovered Windmill software.

  "The Windmill software was a great find for me. 
  The free download was used to evaluate application 
  of the software to my datacq hardware. I then 
  purchased a license for three installations." 
  Jeff Castor, Program Manager, Hercules Pilot Plant

Most of the water treatment chemicals manufactured by 
the plant are polymers, made by typical batch 
polymerisation processes (solution, emulsion and 
dispersion polymerisations). The plant consists of six 
reaction systems. It employs seven Molytek 2702 loggers, 
connected via an RS232 link to a PC by means of a code 
activated switch. The Windmill software suite could 
easily read and control the Molytek loggers through its 
serial driver. The suite also included a software Logger 
application to store and time-stamp many channels of 
different types of data. Process data logged from the 
plant by Windmill include: reactor temperature, reactor 
jacket temperatures (supply and return), reactor jacket 
flowrate, reactor pressure, overhead temperatures 
(vapour, distillate, condenser coolant) and various 
weights, reagent flows and process analytical instrument 
readings.

Readings taken by Windmill are passed to various data 
processing tools for analysis and reporting, including 
Excel, RS/1 and TK!Solver.

The Molytek 2702 was a state of the art logger in the 
1980s. It is built of standard mechanical and electronic 
components and so, can, in theory, be maintained 
indefinitely. For that reason a lot of 2702s are still 
around. They make a good, reliable, hardware front end 
to a low speed data acquisition system.

If you would like to evaluate the Windmill software  
our subscribers can download the free Windmill 4.3 suite 
and ComDebug program.
