Hello,

you be right, it was my mistake with the actual CPU 1515.

The "next generation" of the 1515 which was showing at the sps automation in Nuremberg.
They have this performance with a new Firmware 3.0 and "new" architecture with 2 processors.

They.will be possible to buy in the first quarter of 2023

The "problem" is that you can`t exactly calculate the necessary working memory.
If you migrate the program to TIA-V16 or 17 and compile it, then you can see what is the necessary size of your program.

Otherwise you can't calculate exactly the cycle time of the PLC.

Sorry for my mistake.
