Register Content Description
10,064 Error Delay Counter This parameter specifies the number of poll
attempts to be skipped before trying to re-establish
communications with a slave that has failed to
respond to a command within the time limit set by
the Response Timeout parameter. After the slave
fails to respond, the master will skip sending
commands that should have been sent to the slave
until the number of skipped commands matches
the value entered in this parameter. This creates a
sort of slow poll mode for slaves that are
experiencing communication problems.
