Dear All,

I've got a redundant 410-5H CPU configuration, which are both connected to 1 MTP2200 Unified comfort panel. 
I would like the connection between CPU and HMI to be changed depending on which CPU is master.

I've found attached document from Siemens, but this script used is VB, and not javascript. I'm not experienced with any of those scripting languages. 

Could anyone help me started on converting this VB script to javascript? I've been looking a lot, and it seems this document is not existing for unified panels yet?

I'm still not able to get the changeconnection working. 

In s7 I've a redundant 410-5H configuration. Rack 0 slot 3 IP 10.250.9.2, and Rack 1 slot 3 IP 10.250.9.3

Both CPU's have a cable going to MTP2200 X1 (both X1 ports)

In TIA 17 I use a proxy CPU, which is connected to Rack 0 slot 3 IP 10.250.9.2 over an HMI connection named PLC_Changer_12

I have 2 buttons on HMI screen which have following event when pressed:

Changeconnection:Connection name -->PLC_Changer_12
IP address --> 10.250.9.2
Slot--> 3
Rack --> 0

Changeconnection:Connection name -->PLC_Changer_12
IP address --> 10.250.9.3
Slot--> 3
Rack --> 1

However the only HMI connection that works is the initial one to rack0. Is there anything that I'm missing? Is there anyone that was able to successfully make this work on a unified panel?
