Warm Boot (Write Block)

This block is sent from the ControlLogix processor to the module (output image)
when the module is required to perform a warm-boot (software reset) operation.
This block is commonly sent to the module any time configuration data
modifications are made. This will force the module to read the new configuration
information and to restart. The structure of the control block is shown in the
following table:

Because many of the parameters set in the configuration file require the program
to restart, this function works the same as the cold-boot function. It will cause the
module to exit and restart the program.

Cold Boot (Write Block)

This block is sent from the ControlLogix processor to the module (output image)
when the module is required to perform the cold boot (hardware reset) operation.
This block is sent to the module when a hardware problem is detected by the
ladder logic that requires a hardware reset. The structure of the control block is
shown in the following table:

5.2.7 PROFIBUS Slave Error and Status Data

The PROFIBUS Slave Error and Status Data area is discussed in this section.
This information is available in the PDPS1.InStat.PDPSStatus structure, and
found in the diagnostic PROFIBUS SLAVE STATUS screen. See Diagnostics
and Troubleshooting (page 41) for more information.

The data area is initialized with zeros whenever the module is initialized. This
occurs during a cold-start (power-on) or a warm-boot operation. Counter values
are also initialized to 0 at power up.
