Hi All, when configuring my CFC charts I get the warning message (attached) W: The local data requirements (252 bytes, including OB121 and OB122) of organization block OB83 exceed the warning limit set for the configured local data stack of the corresponding priority class on the connected offline CPU. this message covers all OB82, 83, 85, 86 Any pointers please to solve the problem CPU is a S7414-4HF unit with RAM cards fitted to each CPU.

Hello multimeter there's two ways to solve your problem: 1.) Reduce the numberof TEMP variables for the Blocks that are called from the OB's in question to reduce the local data requirements. 2.)Change the amount of local data that is available for the error OB's (this is what I would do). To do so, go into HWconfig double click on your CPUand adjust the Local data size for the priority class to which your OB's belong(better explained in the attached pic). Please note: Do yourself a favour and use the HELP button on the "Memory" tab and read up on the ramifications of changingthe size of the Local data! I hope this helps |
