We failed to establish ethernet communication between S7-315 and S7-319 S7_315 IP ADRESS: 192.168.0.3 S7_319 IP ADRESS: 192.168.0.1
We have used PUT, GET SFBs on S7-315 (S7-315 Master). DB95 and DB96 same datablocks are downloaded to all CPUs. We get: GET_ERROR =1, GET_STATUS=1 PUT_ERROR =1, PUT_STATUS=1 And obviously no communication. Application programme is attached. We would be glad your guidelines.

Hello VEDAT_BARUH there's a couple ofdefinitive "issues" in your setup which need to be fixedto begin with: 1.) You need to enterthe 319's IP address into the connection details of the(unspecified) S7 connection that you configured in NetPro. 2.) You used SFB14/15 GET/PUT in your logic, these canhowever only be used in an S7-400. Replace them with FB14/15GET/PUT (to be found in "Libraries - SIMATIC_NET_CP - CP 300"folder). Below is a link which has some more details on the configuration of an unspecified connection (and what to look out) which should help too (Note that it decribes a 400 as a partner, but the procedure is the same and the CPU Slot numberof a 300 Partner is always "2". Note too that this linkcontains further links to example GET/PUT programs). What should you watch out for when configuring an unspecified S7 connection for data communication between an S7-300 and an S7-400? An additional example program can also be found below: Sample Program: S7 Communication with blocks FB14 ("GET") und FB15 ("PUT") of the CPU 317-2PN/DP I hope this helps |
