2 SLC 500™ Chassis–Based Processors

Publication 1747-2.39

Features and Benefits

Supports user memory sizes from 1K to 64K.

By offering a wide

range of user memory, SLC 500 modular processors can be used

in a wide variety of applications.

Supports a variety of input and output modules.

The 1746 modular I/O

system offers over 60 types of modules, allowing you to

customize your control solution to meet your application needs.

Supports I/O configurations of up to 3 chassis (30 local I/O slots).

Provides you with the flexibility to expand I/O capacity as

required.

Supports remote I/O and DeviceNet.

The SLC 5/02 and above

processors support up to 4096 discrete inputs and 4096 discrete

outputs which may be a mix of local or remote I/O as well as I/O

on DeviceNet.

Provides superior system throughput.

SLC 500 modular processors

deliver fast overall system throughput times, providing fast

response in high–speed applications.

Supports Ethernet communication.

The SLC 5/05 processors support

10 Mbps Ethernet communication and use the TCP/IP protocol.

The 10Base–T Ethernet channel provides an economical

connection to your Ethernet network.

Supports Data Highway Plus

™

(DH+) communication.

The SLC 5/04

processor provides communication and seamless integration into

the larger Allen–Bradley PLC–5

® network.

Supports DH–485 communication.

Communication via the DH–485

network is available in every processor we ship, reducing your

system cost for processor communication.

Provides a second channel for RS–232 communication for the SLC 5/

03, SLC 5/04, and SLC 5/05 processors.

This allows:

• dial up for remote monitoring and programming

• networking over modems for SCADA master/slave RTU

applications

• an alternate connection for operator interfaces freeing up

peer–to–peer network

• direct communication to ASCII devices such as bar code

decoders and serial printers via a complete set of ASCII

ladder instructions which simplify programming.

Provides user–selectable program security.

The wide range of system

protection capabilities allow you to secure user data and program

files from changes.
