KAESER SIGMA CONTROL 2 User Manual

8.10.2.1 Reaction in the event of a communication malfunction
After switching on the power supply, monitoring for communication malfunctions is suppressed for
a period of time which can be defined by means of the Start td parameter. The setting depends on
the time passing at the bus master between return of power and start of communication via the
bus.
For the communication with SAM 4.0, the value of Start td must be set to 30 s.
SIGMA CONTROL 2 can monitor the bus communication at user level. For this purpose, the bus
master reads a value ("toggle bit") that changes with every bus cycle and returns it without change.
SIGMA CONTROL 2 returns a communication malfunction if the value does not change for a time
longer than set ( Timeout ).
Monitoring for communication malfunction can be activated if needed. For this purpose, the
Send/receive option must be set for the data exchange. Activate the Communication error
check box to enable monitoring for communication malfunctions.
