PROFINET-Device
5.5.1
Configuring the PROFINET-device in CODESYS
Add the PROFINET_Device to the Ethernet interface using the "Add Device"-function and config-
ure the length ofthe in- and output data, which have to be exchanged with the higher-level PROF-
INET-master.
Properties
max. number of I/O data
1024 byte in total
(512 IN + 512 OUT)
NOTE
It can be necessary to increase the PROFINET cycle time for larger BLxx-stations.
Fig. 34: Configuring the PROFINET-device in CODESYS
NOTE
When configuring the I/O-data the following has to be observed: The input data in CODE-
SYS have to be configured as output data in the PROFINET-master configuration and the
output data in CODESYS as input data.
The data thus have to be configured in reverse order in the PROFINET-master configura-
tion ( see also
Configuring the in- and output data (page 55)
).
