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 offersmodularity 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

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 allowstransparent 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 communicate over Ethernet using Modbus-TCP

to allow connection to DCS and other automation controllers.

Smart ModernizationTM

Whether you are an existing user of the 505 Series® or looking for your next control system,

CTI’s Smart Modernization approach ensures the CTI control system you are investing in will be

around for many years to come. Smart Modernization encapsulates our philosophical approach to

making control system advancements while ensuring seamless transitions for our customers

through the continuous evolutionary improvement of our products.

With many 505 Series® products still in use today—some in use for more than 30 years—

the 2500 Series® allows these customers to modernize existing controls without expensive

re-wiring, reprogramming, retraining, or product line shutdowns.Upgrading a control system

with modern-day replacements of old components and/or enhancing performance with new

advanced function modules — all of which are backward compatible — mitigates risk during

migration and allows reuse of existing application programs and hardware — reducing cost

and downtime. That’s what we call Smart ModernizationTM.

Cost-Effective Solutions

Recent introductions of two Advanced Function Modules —an Ethernet Communications

Coprocessor (the ECC1), and a general purpose Application Coprocessor (the ACP1) provide

new options  for cost-effective and minimally disruptive process control solutions.

The ECC1 provides sub-second responses to even a large number of HMI workstations.

It has been used numerous times to improve HMI/SCADA response rates and in support

of HMI/SCADA migrations. Because it communicates with its host processor over a high-speed

Ethernet link instead of the special function I/O interface, items in the data cache can be kept

current, even when the number of cached items is large, and the user-friendly configuration

interface makes implementation fast and simple.

Other ECC1 features allow easyconfiguration of state-of-change peer-to-peer communications

between 2500 Series Systems,requiring no programming in the PLC and minimizing the use

of network bandwidth.

The ACP1 is programmed with CTI’s new open standards IEC61131 compliant development system.

It allows users to add languages, functions and memory organization features to existing CTI

2500 Series®  and Simatic 505®  controllers and is able to exchange data between the RLL

program on the host PLC and the IEC61131 programs.

Simplicity is Fundamental

One of the design requirements we have for every product we make is that it is simple to use.

We have laser-like focus on the needs of industrial process control, including batch,

continuous, and low-to-medium-speed discrete manufacturing processes, and we harness

the best of today’s technology to address core process control needs as simply and efficiently

as possible.  We design our controllers so that it is easy and straight-forward to perform

all of the most widely used process control tasks.

Our goal is to make our products easy to integrate, easy tooperate, and easy to maintain.

The simple memory layout of our controllers is clean and straightforward.

The PLC scan cycle is flexible and deterministic — allowing customconfiguration while

providing control over absolute worst-case cycle time.  All configuration items and

operation of control functions such as PID loops and analog alarms can be setand/or modified

directly from an HMI without dedicated program logic.  We want to get you — and keep you

— up and running as quickly and efficiently as possible.

Continuous Evolutionary Improvement

The 2500 Series® has its roots in the “ahead-of-its-time” Texas Instruments/Simatic

505® Series system known for its robust performance, intuitive design, and elegantly

simple PID and special function programming.  The 2500 Series® reinvigorates and

modernizes this legendary product line with more memory, more speed and many new

features while maintaining backwards compatibility.

The most important feature of every product CTI sells is compatibility

— both backward and forward.  We don’t obsolete our products and expect customers

to buy our latest control system.  Instead, our products are conceived to allow customers

to improve systems incrementally — building on previous investments in equipment,

programming and training.  A brand new controller with modern features will work

seamlessly with I/O modules from ten years ago or from ten years hence. 

This allows you to upgrade your control system at your own pace and with

minimal disruption.
