The 2541 Redundant Processor Manager (RPM) provides an automatic

backup solution for 2500 Series® PLCs. If the active PLC fails, the RPM

will automatically switch the remote I/O to the standby PLC.

Transfer to the standby PLC is bumpless. All remote I/O updates are

mirrored to the standby PLC. In addition, up to 4096 words of user-

defined critical data can be transferred from the active PLC to the 

standby PLC every scan.

Other non-critical data can be transferred over several scans.

The RPM can also switch up to two serially attached operator interface

devices.

IMPORTANT NOTE: Due to extensive component obsolescence issues

and insufficient demand to justify a re-engineering effort, this product

has been matured.  For users needing PLC redundancy in the future,

we have a solution planned based on our new Janus Programmable

Automation Controller which uses two Janus PLCs and a Modbus relay

that switches Remote I/O and Profibus networks from the primary PLC

to the backup in case of a Processor failure.

The 2577 allows a Profibus Master to read any PLC V, WX, X, and C

memory location and write any V, WY, and C memory location over

Profibus.

Features

• No changes required to existing PLC configuration and I/O

• Allows transfer of up to 110 words of data in and 110 words of data

out to Profibus Master

• Maintains statistics and diagnostic information for the Profibus network

• Auto-senses Profibus baud rate

• Integrates CTI 2500 Series® and Simatic® 505 systems into S7 and

PCS7 designs

The 2500S family of Slice I/O modules expands the capability of 2500

Series® Systems to include small drops of I/O connected over Ethernet.

Slice I/O modules communicate to 2500 Series® Processors using CAMP

protocol and read/write directly to the PLC memory or I/O image table.

This allows transparent integration into the 2500 Series® system without

the requirement for any complicated configuration step.

Ethernet connection to the CPU can be accomplished using the on-board

port on 2500-Cxxx Processors, or using a 2572 / 2572-A Ethernet module.

Note that when using 2572 or 2572-A modules, Slice I/O can be connected

even to legacy Siemens® and Texas Instruments PLCs.

Several models of Slice I/O are available with different mixes of I/O and with

additional communications options including RS232/485 and 900MHz radio.

Slice I/O modules feature Universal Analog Inputs which allow connection

of 0-5V, 0-20mA, thermocouple, and RTD sensors. All Slice I/O modules can

also be configured to communicate over Ethernet using Modbus-TCP.

Note: This unit is designed to work on a battery so +12VDC is operating

voltage, not +24VDC.

NOTE: THIS PRODUCT IS MATURE AND IS  NO LONGER AVAILABLE FOR

PURCHASE.
