Hello,

we don't know why you want increase this area, what is the reason to do that. Can you be more clear about your HW and what you want to do, what devices you have on bus? In case you have only one, it can be problem, you need to be more effective with your code probably. In case you have on CP attached more PB Slaves, solution can be next CP attached and set there some of Slave/s to have previous network more available for data inside I/O. You can have 2 independed PB networks without problems. Describe pls your situation better.
