Selecting Modular
Processors SLC 500 modular processors are designed to meet a wide range of
applications, from small stand-alone to large distributed systems and
from simple to complex applications.
Processor Features
Memory size - The SLC 500 modular processors memory is user
configurable for either data storage or program storage. Memory size
is 1 K...64 K.
I/O points - The SLC 5/01 processor supports addressing of up to 3940
I/O. The SLC 5/02, SLC 5/03, SLC 5/04, and SLC 5/05 processors
support addressing of 4096 I/O. The SLC 500 modular processors are
supported by over 60 different I/O modules including digital, analog,
and intelligent I/O.
Performance - The SLC 500 modular processors are designed with
throughput performance in mind. The program scan time for a typical
instruction mix are 0.9 ms/K...8.0 ms/K depending on the processor.
I/O scan times are 0.25 ms...2.6 ms depending on the processor and
I/O installed in the system.
Advanced instruction support - The instructions available depends on
the processor used. The following table lists the instructions
supported by the SLC 500 modular processors.
