ADDITIONAL PROjEcT DESIGN FOR SyNcHRONOUS cOMMUNIcATION AccORDING PROFINET IO-IRT
8.2 Additional project design for synchronous communication according PROFINET IO-
IRT
Additional settings must also be made for the slave if PROFINET IO-IRT shall be acti-
vated. First, the exact topology of the PROFINET network must be specified for synchro-
nous communication. This is done by right-click to the PROFINET-IO system and selec-
tion of PROFINET IO topology. The graphical view is selected in the following picture,
since this gives the best overview. In this example Port2 was selected for the PROFINET
communication on control side and Port1on slave side, since the communication with
the programming unit is done via Port1 of the control CPU.
