CTI 2500 Series® Cost-Effective Solutions

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.

Embedded client/server protocols perform data transfers based on configuration tables without

the need for any additional logic in the PLC or ACP1 application program. 

It has been used to build systems using 2500 Series®  Processors to operate dozens of

variable speed drives connected over Ethernet/IP and Modbus-TCP to control material movement

in the factory.The unique capabilities of Function Block Diagram (FBD) programming in the ACP1

allowed the user to develop a single function block which controlled all the drives in the system.

Development and maintenance of the software were dramatically simplified compared to doing

the same project in RLL.

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.
