Using WinCC Flex with Redundant 315-2PN/DP CPUs

Raymondk Posts: 62 Rating: (0)	Hello Everyone, I am using Wincc Flex Configuration and Runtime package on a PC which is connected to a Redundant S7300 system 315-2PN/DP (PLC A and PLC B) via ehternent. My question: In WinCC Flex when I tag a button for example,I tag to a bitfrom one CPU connection (PLC A) so press the button and the bit is set high. If PLC A goes to stop and PLC B takes over the bit is not set high because it was only set in PLC A. IfIpress the button the bit status does not change on PLC B. How can I make the connection in WinCC Flex change from PLC A to PLC B or B to A? Thanks, Raymondk
