'S7 F Distributer' of FB223 (F_SENDDP) and FB224 (F_RCVDP) want to use the DP-DP communication. Hardware configuration is as follows: DP-Master: CPU 412-3HJ14 address 2 DP-I-Slave: CPU 315F-2DP address 3 Reference manual Safety-related_master-I-slave_communication_via_PROFIBUS_DP_27044338_en.pdf (In this document, S7-300 and the communication was ET200S) S7-315F reference compile error occurs when you create a program. Compile Error: F-application blocks for safety-related CPU-CPU communication may only be called in the F-program block. Thanks for reading long Please tell me if this question is inappropriate for this forum.

Please see the section 8.8 of the S7DistSafety manual. You will need a 300F Profinet version and must use Ethernet with S7 connections. Please read the getting started manual for S7 Distributed Safety see attached. The safety blocks must be called within an F-FC or F-FB which you create. You can create an FFB/FFC in the same way as a standard block except you must choose the F-LAD or F-FBD language instead of LAD/FBD. Call FRCV-S7 at the beginning of the program and FSEND-S7 at the end. In the blocks folder insert an FC and use the language called FCall instead of FLAD/FFBD. Double click the FCALL block and assign your program to the FCALL. You then need to call the FCALL in either a cyclic OB or OB1. Attachment s7fcoGSb.pdf (1159 Downloads)
