8.3 Diagnosis parameters
1 byte is available per DDL participant. Every parameter
byte can be individually set for every participant. The
parameters are not transferred cyclicly.
The DDL participants provide the DDL master with this
function. Several field bus systems (e.g. PROFIBUS DP)
present comfortable setting possibilities together with
the PLC. This is not currently available with other field bus
systems. They use default parameters instead.
