I have built several Remote Control Centers.
One spanning several buildings. That one was in Cohasset California,
and was the Remote Broadcast Station for KHSL-TV.
I had many microprocessor modules distributed in buildings and in equipment in those buildings.
I controlled all broadcast transmitters, Microwave gear, Cameras, and even Security.
All modules communicated with each other over my modified RS485 lines. Each module had control relays to control equipment.
And each module had input lines to measure and see events. Modules communicated at will. Today it could be called "AI".
The communication system was similar to the CAN system in that all modules could communicate at the same time on the same lines.
My advantage was that I could communicate many hundreds of feet. The CAN system can not.
My system also has Human Speech. Any module can speak, by communicating to a Speaking Module.
By division of labor, the Speaking Module's sole purpose is to technically speak. It verbally forms words and sentences.
My Secretarial Program ties in to my Remote Control System at home and in the RV;
Enhancing its awareness and reach.

Here, the secretaries have access to the outside temperature.
But, I have dozens of other local physical parameters available if I want the girls to work with it.
Each module keeps a week long history too. It is located internal locally in the module.
