Note: Not all controllers support program access to the configuration file. Refer to
your controller's user manual.
After module installation, you must configure operation details, such as thermocouple
type, temperature units, etc., for each channel. Channel configuration data for the module
is stored in the controller configuration file, which is both readable and writable.
The configuration data file is shown below. Bit definitions are provided in Channel
Configuration, below. Detailed definitions of each of the configuration parameters
follow the table.

4.2.1 Configuration Data File

The default value of the configuration data is represented by zeros in the data file. The
structure of the channel configuration file is shown below.
