If a PROFINET CP is used...
The following is to be taken into account:
•
Hardware configuration:
Depending on the device type, several PROFINET CPs must be configured in a SIMATIC
300 station, however only exactly one of them may be configured for PROFINET CBA .
Depending on the device type, several PROFINET CPs may be configured in the central
rack in a SIMATIC 400 station, however only exactly one of them may be configured for
PROFINET CBA .
•
Configuration for standard components: When you configure the Ethernet port, you must:
–
select the "IP address is used" option
–
deselect the "Set MAC address / Use ISO protocol" option.
•
Copy block in the S7 program:
The PN_InOut function block (FB 88 or FB 90) must be called in the CPU program. This
function block is a PROFINET copy block. It transfers the data from the interface DB to
the PROFINET CP and from the PROFINET CP to the interface DB.
The FB 88/FB 90 must be copied from the PROFINET system library to the block folder
for the STEP 7 basic project. For additional information, refer to the help relating to the
block and the CP device manual.
