Hi

Im having some issues regarding profinet communication between 2 PLC´s, I hope I can get some help from the specialists ;)

The communications is between S7 315-PN/DP (where I made the configuration using put and get) and S7 315 2DP + CP343-1. I can ping both plc´s from the network so the cables look good but the stats is always 25 job in progress and then 2. I cant figure whats the problem.

I send the program in the attach (FC1 Ethernet).

BestRegards

Hello,

you use old Version of the FB14 and FB15. Just have a look at standard library ->  communication blocks, here you´ll find a Version 1.2 of them.

Copy it into your projekt, load the plc  315-2 PN and try again!

Hey, yes it sems that the Versions of SFB14/15 are still V1.1!

Anyway SFB 14/15 is to use in S7-400, FB 14/15 for S7-300 and if an CP is used in S7-300 there are another pair FB14/15 in SIMATIC_NET_CP library. 

Question: Have you load the 1_ETA from NetPro? You must do that! 

If it´s not solved jet, I´ve one more idea!

At first go into HW-Config and dubbleclick at plc, in register communications you must free some reservations! Here are 10 connections reserved for S7-Basic communication, you don´t use!!!

Second go to NetPro and delete the S7- connection on ETA-external! Define a new connection -> unspecified -> S7-connection -> it wil be set up in that plc only! enter the IP-Adress for CP343-1LEAN and go to adress detail and enter on partner side rack:0 slot: 2 connectiontype: 03

load again both plc from NetPro!
