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 easy

configuration 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.
