Understanding
Registers
The first part of this section gives you a quick overview of way the Modbus
Communications Card uses registers to control and/or monitor APEX functions. The
second part gives you step-by-step instructions about how to use the Modbus registers
to change products, get summary statistics (such as the total reject count), and back up
all your important APEX settings. And the final part, which is presented in the form of
table, gives you a complete summary of all Modbus registers used by the APEX.

Data Handling
