the received value is out of range, bit 2 will be set in the error output of the process. If due to a timing
problem a process is never evaluated during a sample interval, bit 1 will be set.
To simplify analysis of multiple problems within a configuration, an Error Checking Alarm Process can
be created (Category 3, Number 12). It will report the total number of processes reporting errors and the
first four process record numbers as well as their error codes.
10.5. DEFINING CONSTANTS
Twenty user-definable floating-point constants are available to the user in the Constants Menu.

Constants defined in the Constants Menu can be used as inputs to Process
Records or outputted in the Data Output Records.
You might want to use a constant as a replacement to real data collected by
a sensor when a particular sensor is not available.
The Constants Menu is accessible from the System Functions Menu by typing the command K{ENTER}.
The Constants Menu will look something like this:

Some versions of ZenoSoft™ support as many as 60 constants. Since only 20 constants can be adequately
shown on a single page, options P and N were added to the Constants Menu to allow you to see constants numbered
greater than 20.
