Tags missing or disappear from ArchestrA - Dassidirect3

[pisoj]

Hello, I have yet another question regarding Intouch
I need to establish a communication between S7 400 PLC and InTouch v14.
I am using Archestra and DASSIDIRECT.3 driver.

In InTouch I made Access Name Test_1, Node Name is my PC, Application Name is DASSIDIRECT, Topic Name is Test_1; Protocol is SuiteLink but i tried also with DDE.
In Archestra under DASSIDIRECT i made new S7Cp Object with next properties:
-Network Adress: adress of my PLC; Local and Remte TSAP are default as everythin else.
-Under Device Groups i made a group named Test_1 (same as in InTouch)

First problem was that tags in InTouch were not displayed in Archestra Management Console in Diagnostics Tab. I have managed to get my tags to show, but sometimes they suddenly disappear and only way to make them appear again is to disconnect and connect Ethernet cable from my PC.

Any ideas why?

Thanks in advance.
