NI PXI-1045Series 90-30 CPU Capacities The following table describes the maximum capacities and operating features for the Series 90-30 PLC CPU models. For State Logic CPUs, see “System Specifications for Series 90-30 State Logic CPUs” in Chapter 9.Maximum of 160 combined I + O points. 2 Maximum of 320 combined I + O points. 3 Configurable from 128 to 32,640 words, in 128 word increments. 4 Depends on assigned values for configurable word memory (%R, %AQ, %AI). Maximum is 240K Bytes. 5 CPU352 and CPU374 have hardware-based floating point math. Other CPUs have firmware-based floating point math. User Memory Addresses (References) Data in the Series 90-30 PLC programs is referenced by its memory address. A reference indicates the way that data is stored in the PLC. A reference specifies both a memory type and a precise location (number) within that memory type. For example: %I00001 specifies address 1 in input memory. %R00256 specifies address 256 in register memory.
