I am trying to establish a connexion between a CPU 414 2 DP with an 443-1 CP and a CPU 317 2 PN/DN with integrated PN port. I manage to transfer data with PUT/GET instructionas and with a S7 connexion. I will like to do the same using an ISO on TCP connexion and with AG-Seng AG-Receive, but I don´t know how to parametrize the both interfaces. Any help?

For the CPU 414 it needs the use of the AGSEND, but for the CPU 317 it needs the use of the TSEND instruction, as it has integrated PN port. I will upload my project to see if something´s misssing.

Pittiplatsch Posts: 1368 Rating: (128)	You are right, with a S7-300 PN-CPU, you use the TCON, TSEND and TDISCON. Then this FAQ is relevant for you http://support.automation.siemens.com/WW/view/de/29737976 Can you post only a screenshot from your AGSEND-CALL, TCON_Param and TADDR_Param? Thx

But it does´n work . On the CPU 400 AGSEND status I have the 7000 error and on on the CPU 300 I have the error80B7 .

Pittiplatsch Posts: 1368 Rating: (128)	There is an mistake in the TCON_Param. Please check the parameters: block_length, local_tsap_id_len, rem_subnet_id_len, rem_staddr_len, rem_tsap_id_len, next_staddr_len

Pittiplatsch Posts: 1368 Rating: (128)	can you post the TCON_PARAM in "online view"? And the AG_SEND configuration on other side!
