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.
