Diagnostics; Process Data Transfer - Lenze i55AE125B Manual

Diagnostics

The controlled node indicates applied diagnostic data by an emergency message to the man-
aging node.
Details
The XXXX parameter serves to suppress the transmission of emergency messages to the
•
managing node. Thus, errors of a certain type can be suppressed in a targeted way.
Errors and warnings of the inverter and the network option are sent as extended diagnos-
•
tic messages to the managing node:

Process data transfer

POWERLINK transfers process data, parameter data, configuration data and diagnostic data
between the managing node and the involved controlled nodes. Depending on their time-crit-
ical behaviour, the data is transmitted via corresponding communication channels.
Details
Process data is transmitted cyclically between the managing node and the controlled node
•
(permanent exchange of current input and output data).
The transfer of process data is time-critical.
•
The process data serves to control the POWERLINK nodes.
•
The process data can be directly accessed by the managin node. The data in the PLC, for
•
instance, are directly stored in the I/O area.
The contents of the process data are defined via I/O data mapping.
•
Process data are not saved in the device.
