4.3 Variable Configuration

Before an application task can be written, you need to configure, or

define, systemĆwide data such as the registers on the Pulsetach

Input module as variables. These are variables that must be globally

accessible to more than one task in the rack.

For DCS 5000 and AutoMax Version 2.1 and earlier, you define

systemĆwide variables by writing a Configuration task. For AutoMax

Version 3.0 and later, you define systemĆwide variables using the

AutoMax Programming Executive configuration forms. After the

variables are defined, you can generate the configuration file

automatically.

If you are using AutoMax Version 2.1 or earlier, refer to Appendix F

for examples that show how to define variables in the configuration

task. If you are using AutoMax Version 3.0 or later, see the AutoMax

Programming Executive for information about configuring variables.
