Change PLC Connection thru script

Nitin G

...
I want to keep only one PLC active.

Dear Nitin,

I have checked it for TCP/IP connection successfully.
Please go through following steps.

(1) Create an MPI connection of adrress say 2.
(2) Create External Tags linked with PLC.
(3) Open any graphics page.
(4) Click anywhere which allows Dynamic Wizards to be visible.
(5) Double Click on "Create Redundant Connection" Dynamic Wizard.
(6) Go through the forms nevigation.
(7) When it asks for Alternate Address, Change it as 3 instead of 2. See Main connection format and then change accordingly. Main Connection Name: Test
Main Connection :MPI,2,0,,0,2,02 Alternate Connection :MPI,3,0,,0,2,02
(8) Mark Change connection Automatically Checkbox.
(9)Save and close picture.
(10) You have to mark Global Script Runtime checkbox in Computer Name Properties.
(11) Alternate connection Tags will be automatically generated in your MPI connection Group.
(12) In that A tag will be there name @AlternateConnection Address of type char.
(13) Place a button on Graphics Screen and write event on its left click:
SetTagChar("@Test@AlternateConnectionAddress","MPI,3,0,,0,2,02");

I have checked it with redundant system. I hope it will work for Stand alone system also. Else study auto generated C-Script after implementing step-9.
Go through Software Redundancy help in WinCC.
If any problem, do not hesitate for further assistance.
