CPU 416 2DP MLFB No. 6ES7416-2XL01-0AB0 with CP443 MLFB No. 6GK7443-1EX11-0XE0 CPU 416 2DP MLFB No. 6ES7416-2XK02-0AB0 with CP443 MLFB No. 6GK7443-1EX11-0XE0 CPU 416 2DP MLFB No. 6ES7416-2XN05-0AB0 with CP443 MLFB No. 6GK7443-1EX30-0XE0 and CPU 417 2DP MLFB No. 6ES7417-4XL04-0AB0 with CP443 MLFB No. 6GK7443-1EX20-0XE0Now we want to interconnect all the four CPUs through Ethernet switches and intend to have global data transfers.Can we do it ?CPUs and CPs are all different from one set to other.Will it be any problem ?

You can find more information’s and exampleshere: CPU-CPU communication with SIMATIC controllers, SIMATIC NET, Program blocks for SIMATIC NET S7 CPs, Programming Manualor Industrial Ethernet S7-300/400 CPs -- Configuring and programming communication -- Using communication blocks
