• built-in isolation.
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.
Barrel Control
Select barrel control for multiple–zone applications in which there is
thermal conduction between the zones. Injection molding and
extrusion are good example applications because they use multiple
heater bands (zones) mounted on one thermal conductor (the metal
barrel). The barrel conducts heat between different zones. If you
select barrel control, also select between inner and outer zones (word
1, bit 13 for channel 1). A barrel loop is autotuned as the temperature
rises from a cold start to a temperature setpoint during startup.
