The diagnostic data are requested by the bus node with the
function Slave_Diag (see chap. 3.3.3).
With the function Set_Prm you can determine the watchdog
time (WD_Fact_1, Octet 2, WD_Fact_2, Octet 3).
The behaviour of the bus node in case of error (e.g. bus fail-
ure) depends on the parameterisation (see chap. 2.8).
