-3200 User Manual
This section describes several topics of an advanced nature. You should not read this section until you
have a good understanding of creating basic ZENO
®
-3200 configurations.
The topics covered in this section are varied:
Understanding ZENO
®
-3200 Timing
The Universal Serial Interface
Configurations with Multiple Serial Sensors
Sharing Data between multiple ZENO
®
-3200's (multiprocessing)
12.1. UNDERSTANDING ZENO
®
-3200 TIMING
The key to understanding timing in the ZENO
®
-3200 can be summarized by the following statements.
Each function that the ZENO
®
-3200 is required to do by its configuration requires a certain amount of
time for completion.
The time that each function requires must be balanced with each other in order for the ZENO
®
-3200
to successfully carry out all the functions defined in a configuration.
When the amounts of time various functions within a configuration are imbalanced, the ZENO
®
-3200
will be unable to carry out the various functions for a configuration, and errors will result.
Many of the errors that occur in a ZENO
®
-3200 configuration are the result
of the user not understanding how much time each function will require
within the configuration.

-3200 Timing Structure
ZENO
®
-3200 timing structure can be illustrated with the following diagram showing four different layers.
Each layer is dependent upon the layers beneath it!
