registers with individual bit descriptions are shown with the
bits broken up into groups of four for ease of interpretation in
monitoring the registers in hexadecimal format.
At times register and bit references will be in the form of
"RA,bB," where "A” is the register number and "B" is the bit
number.
4.1 Configuration
Before an application program can be written, it is necessary
to configure the definitions of variables that must be
accessible to all tasks in the rack. This section describes how
to configure the module.
If you are using V3.0 or later of the Programming Executive
software, you can configure the module using a special
software "form" that allows you to fill in the names of the
registers and bits. See the Programming Executive
instruction manual for more information on configuration
forms.
If you are using an earlier version of the programming
executive, you will need to create a configuration task to
configure the registers/bits on the module. See Appendix H,
for more information on creating a configuration task.
