Hi, I have a big project which has 6 17-slots Racks connected by Controlnet. How much the maxium scheduled Controlnet connection? If I use comm formt:Rack Optimization instead of input/output Data for DI/DO Cards, Will it save Connections? Thanks,
Rockwell controlnet Connection?

Yes, using Rack Optimisation will reduce the number of connections utilised.
Example : A 17-slot chassis full of Digital* I/O modules will require 16 connections. Using Rack-Optimisation reduces that to 1 connection.
* Analog I/O modules cannot be added to the Rack Optimisation method.
Disadvantages : None except that all digital I/O in the chassis has to run at the same RPI rate. If you do need an I/O module to run at a different rate, it can be added to the configuration so as not to use Rack Optimisation.

What's the maximum connections for Scheduled controlnet?
Yes, you must delete and put back in Rack-Optimised format.
The reason is that this changes the Module-Defined tags that are created, and any existing I/O references are aliased into the rack-optimised tags. This subject usually takes me an up to an hour to get across to most people.
Connection usage is limited by :-
a) The processor - 250 maximum
b) The comms module - the CN2 have twice the nunber of connections than the CNB, the specs will tell you how many each module will support.
