Configure TCP-server

[DmSilkin]

Hello!
I have an IEC-remote driver connected to the redundant system. Configs are:
1. Project #1
[general]
...
data = "Host#1"
event = "Host#1"
[iec_72]
tcpServerPort = 2404
2. Project #2
[general]
...
data = "Host#2"
event = "Host#2"
[iec_72]
tcpServerPort = 2404

This driver is a TCP-server. For now, TCP-client is connected to the driver but ConnectionState is inactive on host#1 and active on host#2. Can i configure the driver to have both hosts active OR can i have the ConnectionState always to an active host?

Are you starting the IEC driver which connect to server 1 and server 2 on the same machine?
Why aren't you starting only one driver which connects to both servers?

If you want to start a remote driver which connects only to server 2 in a redundant system you have to add additional config entries to give the driver the information which server he connects to.
For details please have a look at the WinCC OA Documentation and the config.redu file of the WinCC OA installation.

I'm starting driver on the different machines. Each of its IEC-driver connects to only one host as i mentioned before.
If i start with config:
data = "host#1$host#2"
event = "host#1$host#2"
I get the connection error on my TCP-client and error in PVSS.log:
Unexpected state, InetConnection, searchByAddr, No valid host TCP CLIENT

As described in my previous post you have to add some config entries for the driver connecting only to server 2.
The entries are necessary to give the driver the information that the "_2" datapoints must be used.
