Command 16 Error
For every command that has an error, the module automatically sets the poll
delay parameter to 30 seconds. This instructs the module to wait 30 seconds
until it attempts to issue the command again.
As the commands in the Client Command Last are polled and executed, an error
value is maintained in the module for each command. This error list can be
transferred to the processor.
