CTI 2500 Series® Slice Ethernet Remote I/O System

2500 Series® Slice   Ethernet Remote I/O System

OVERVIEW

The 2500 Series® Slice I/O System is designed for use in a

broad range of applications.  It is compatible with the 2500

Series® Programmable Automation Control System and

offers users the ability to place I/O points in multiple

remote locations without the need for I/O bases and RBCs.

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, using a 2572 / 2572-A/B Ethernet module, or

using the 2500P-ECC1 Ethernet Communications

Coprocessor.  Note that when using 2572 or 2572-A/B

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

Powerful & Cost-Effective Ethernet I/O

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

capability of 2500 Series® Systems to include small

modules of I/O connected over Ethernet.  It offers

modularity down to a few I/O points without the need for

an I/O base and RBC.

The CTI 2500 Series®  Slice Ethernet I/O System offers:

• Connection to CTI and legacy Siemens®/TI

CPUs over Ethernet using CAMP

• Connection to DCS or other automation

controllers using Modbus-TCP

• Several models with differing I/O capabilities to

customize the solution to your needs

• Serial RS232/485 and 900MHz radio options for

additional communications flexibility (900MHz

wireless subject to import limitation, depending

on country)

• Extensive intelligent features for processing

attached I/O signals:

 Totalization, filtering, forcing, inversion,

runtime, and counting on digital inputs

 Frequency out (with PWM) and

synchronization on digital outputs

 Filtering, averaging, scaling and totalization

on analog inputs

 Data logging and trending

• All module configuration done using a simple

web browser interface

• Wide –40°C to +70°C operating temperature

range
