Defining Variables in the
Configuration Task
Before any application programs can be written, it is necessary to configure, or
set, the definitions of systemĆwide variables, i.e. those that must be globally
accessible to all tasks.
This section describes how to configure the system variables on this input
module. Refer to the figure below. Note that this procedure is only used if you are
using the Programming Executive Software Version 2.1 or earlier.

32 Bit Register Reference
Use the following method to reference 32 bits as a single register. 32 bit register
reference is commonly used to read indicated weight or tare weight. The
symbolic name of each register should be as meaningful as possible.
nnnnnăIODEFăSYMBOLIC_NAME![ SLOT=s, REGISTER=r]
When referenced as a long register of 32 bits, register r" is the most significant
16 bits and register r+1" is the least significant 16 bits.
