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.
Model 20 I/O Modules The following I/O modules are available for the Series 90-20 PLC. Each module is listed by
catalog number, number of I/O points, and a brief description. The I/O is integrated into a
baseplate along with the power supply. For the specifications and wiring information of each
module, refer to chapter 5 in the Series 90-20 Programmable Controller User’s Manual, GFK-
0551.
