I notice that “The RMC75E supports up to 128 registers in each direction, and the RMC150 supports up to 256 registers in each direction. Notice that at the time of this writing (September 2010), Siemens S7 PLCs are limited to 63 registers in each direction.”

Until now，Can 128 registers be supported? i need 128 registers in incoming direction .

I am not certain, but it appears the Siemens PLCs still have that limit. However, for a definite answer, you should contact Siemens.
