Control Execution Environment

[milan2003_07]

Hello,

The [FONT=&quot]Control Execution Environment (CEE) [/FONT]is the execution and scheduling environment for the 1757-PLX52 Control Processor. It is available in two base execution rates, 50 msec (normal) and 5 msec (fast) and is selected and loaded into the processor with Control Builder, so you can select the execution speed at development time.

What is "control execution environment"? In spite of the explanation given, it's still a bit difficult to comprehend the meaning.

Thanks

'Environment' is a pretty all-encompassing word, and it's commonly used in the field of software - in particular 'software development environment (a set of one or more interacting bits of software that make it easier for a programmer to develop more software).

In this case, this sort of 'programming environment' is available to make it easier to develop software that manipulates how some control software (software that controls something) is executed. I think.

But this is an area of a great degree of abstraction. Most people don't think about the fact that any long-lived software (say, WinWord) was developed by anyone. In reality, hundreds (or maybe thousands) of developers have worked on it, using dozens of different programming languages, and - over time - many different development environments. (But what do I know:-? ;-))

The control system can be set up with different tasks and you can select how fast/often they run individually. This is the "environment" in which the tasks are executed.

You select how the tasks are "scheduled" and "executed" (i.e. which tasks run in what order and how often they run.
