6 Configuring and Programming the CP as a PROFINET IO Device

B3L−31

CP 343-1 Lean for Industrial Ethernet / Manual Part B3L

Release 03/2007

C79000-G8976-C198-04

Transfer the process inputs (DB10) to the I addresses with PNIO_SEND

For the configured I addresses, you will need to make data areas available on the

PROFINET IO device, for example in a DB (in this example in a DB10) that

contains not only the process data but also the data areas for the IOCS status

information.
