Global Data

The Series 90-30 PLC supports very fast sharing of data between multiple CPUs using Genius global data. The Genius Bus Controller, IC693BEM331 in CPU, version 5 and later, and the Enhanced Genius Communications Module, IC693CMM302, can broadcast up to 128 bytes of data to other PLCs or computers. They can receive up to 128 bytes from each of the up to 30 other Genius controllers on the network. Data can be broadcast from or received into any memory type, not just %G global bits. The original Genius Communications Module, IC693CMM301, is limited to fixed %G addresses and can only exchange 32 bits per serial bus address from SBA 16 to 23. This module should not be used as the enhanced GCM has over 100 times the capability.

Global data can be shared between Series Five, Series Six, and Series 90 PLCs existing on the same Genius I/O bus.
