9.11.4 Diagnoscs
The controlled node indicates applied diagnosc 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 opon are sent as extended diagnos-
c messages to the managing node:

9.11.5 Process data transfer
POWERLINK transfers process data, parameter data, conguraon data and diagnosc data
between the managing node and the involved controlled nodes. Depending on their me-crit-
ical behaviour, the data is transmied via corresponding communicaon channels.
Details
•
Process data is transmied cyclically between the managing node and the controlled node
(permanent exchange of current input and output data).
•
The transfer of process data is me-crical.
•
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 dened via I/O data mapping.
•
Process data are not saved in the device.
Process data (RxPDO):
•
0x4008:001 (P590.01) (NetWordIN1)
•
0x400B:013 (P592.13) (Network frequency setpoint [+/-16384])
Process data (TxPDO):
•
0x400A:001 (P591.01) (NetWordOUT1)
•
0x400C:009 (P593.09) (Frequency [+/-16384])
•
0x2D88 (P104.00) (Motor current)
•
0x4050:002 (internal parameters)
