Monitoring

The response to POWERLINK errors such as the lack of PDOs can be configured via the following parameters.
 
In the "Operational" state, the controlled node detects an interruption of the POWERLINK communication, e. g. by cable breakage or failure of the managing node.
The response to the interrupted communication is controlled by the following settings:
1.
The watchdog monitoring time defined in the managing node is transferred to the
controlled node when the POWERLINK communication is initialised.
 
2.
If the controlled node does not receive any valid process data in the "Operational" state, the process data are handled in a general (not network-specific) object according to the setting. Thus, the data sent last by the managing node can be used or the process data is set to zero.
 
3.
'After the communication has failed...
 
–
the controlled node changes to the "Pre-Operational" state.
 
–
the red "BE" LED on the front of the inverter is permanently on. Status LEDs 
 
–
the error response set in 0x2859:001 is effected (default setting: "Trouble").
 
 
 
The parameters for setting network monitoring functions are described below.
