Function no. 4828 + m * 64 + 8 (channel 0 ... 3) m = module number (0 ... 47)
Description Sets whether or not a diagnostic message is to be displayed after
a limit value set with parameters 15 ... 22 is exceeded or not reached
value falls below the minimum sensor temperature range
value exceeds the maximum sensor temperature range.
The limit value monitoring can be set for the individual channels independently of
each other.
