3.1.3 Process data communication (general)

By means of process data communication new process output data (PDOUT) can be sent to the KEB PROFINET
slave and the actual process input data (PDIN) can be determined. Which parameters concern to the data is
determined by the process data mapping in the frequency inverter control.
Currently a maximum of 16byte process data for each data direction can be transferred.
The KEB F5 PROFINET operator expects PDOUT1 data on PROFINET in network byte order. For a combined
mapping of 1x32 bit and 2x16 bit (PDOUT1Hsp5Service = 50) the following transmission sequence results:
Byte 0
MS Byte
MS ByteMost significant Byte (most significant byte)
LS Byte: Least significant Byte (least significant byte)
Analog applies for the transmission sequence of the PDIN data, if PDIN1Hsp5Service = 50.

3.1.4 Process data communication (synchronous mode)

All communication tasks between operator and frequency inverter control are strictly cyclical processed with only
one internal PDO (Process Data Object). Minimum cycle time is 2000 µs (see ComCycle).The process data as-
signment is determined here by parameters of the pd-group in the frequency inverter control.
Operator parameters
• Fb05 PDOUT1_Hsp5Service
• Fb06 PDIN1_Hsp5Service
• Fb07 PDIN1_Cycle
• Fb08 PDOUT2_Hsp5Service
• Fb09 PDIN2_Hsp5Service
are not significant. The real number of process data bytes to be exchanged is determined also by the setting of
parameters CfgNrPdins and CfgNrPdouts.

3.1.5 PROFINET-IRT communication and synchronous mode

The internal synchronous mode and the PROFINET-IRT communication are independent from each other. The
PROFINET-IRT communication makes sense only in synchronous mode. The synchronous mode operates ti-
mer-controlled independent of external synchronization signals. If the synchronous mode is active and also the
PROFINET-IRT communication, the KEB F5 PROFINET operator receives a synchronization signal (start of red
phase/outputs valid) on which the operator tries to synchronize. The required time interval between IRT-synch
signal and the following start of the internal synchronous communication cycle is adjustable via parameter Fb02:
