Description

The CTI Workbench IDE is used for configuration of module parameters

and development of the user application program for the new generation

of CTI IEC-61131 compatible products, including the 2500P-ACP1

Application Coprocessor. CTI Workbench is a full-featured development

environment with integrated programming editor, I/O and fieldbus

configuration tool, debugger, data monitor, and simulator.

CTI Workbench is PLCopen certified, and may be used to develop programs

that adhere to IEC-61131-3 requirements.

The application program may be developed in any of five

IEC-61131 programming languages:

 Ladder Diagram (LD)

 Function Block Diagram (FBD)

 Structured Text (ST)

 Instruction List (IL)

 Sequential Function Chart (SFC)

A complete library of functions is provided to perform the following tasks:

 Complex mathematical computations

 Boolean logic

 File management

 String handling

 Timer/Counter operations

 PID control

 Real-time data logging

CTI Workbench is compatible with Microsoft Windows® 7. 8. 8.1. and 10.

Making Ethernet Connections

The 2500P-ECC1 module provides two Ethernet port connectors on the front panel.

Both ports connect to a three port switch on the module circuit board.

The third port of the switch is connected to the ECC1 module microprocessor.

This design provides additional flexibility in connecting to the Host Controller and the network.

The switch circuit also provides hardware protection against network traffic storms.

The ECC1 module must have an Ethernet path to the Host Controller and the network containing

the devices with which it will communicate.

Direct Connection to the Host Controller

If a single 2500P-ECC1 is installed in the same base as the Host controller, an Ethernet cable

(Cat 5 or Cat 5e) can be used to connect one Ethernet port on the ECC1 module directly to

the Ethernet port of the 2500 Series® controller.  The other port is then connected to the

network switch.

An advantage of this method is that the embedded switch on the 2500P-ECC1 can provide

broadcast storm protection for the 2500 Series® programmable controller.

Connection via a Network Switch

If multiple 2500-ECC1 modules are communicating with the Host Controller, they should be

connected via an external Ethernet switch.

In this example, port 1 of the ECC1 should not be connected to the network. However, you

could directly connect a laptop PC to this port for programming or maintenance tasks.

Installation

Module Installation

The 2500P-ECC1 can be installed in a CTI 2500 Series or SIMATIC® 505 PLC base. Before installing the

module, remove AC power from the base. Using the guides, align the circuit board with one of the I/O

slot connectors in the base. Slide the 2500P-ECC1 module into the rack until the connector seats. Then

use the thumbscrews to secure the module in the rack.

Connection via a Network Switch

If multiple 2500-ECC1 modules are communicating with the Host Controller, they should be

connected via an external Ethernet switch.

In this example, port 1 of the ECC1 should not be connected to the network. However, you

could directly connect a laptop PC to this port for programming or maintenance tasks.

Apply power to the ECC1 Module

After installing the module, apply power to the base and observe the module LEDs. 

The expected module behavior will depend on whether you transferred the configuration via

the SD card or you chose to transfer the configuration later via the Ethernet port.

The 2500P-ECC1 module communicates with the 2500 Series® controller via a high speed

Ethernet link. Data is transferred between the controller and module using a high density

Ethernet messaging protocol, which is capable of transferring a large amount of data while

minimizing the impact on the 2500 Series® controller.  The controller processes data transfer

requests from the 2500P-ECC1 in a configurable time slice, allowing the user to limit the amount

of scan time used to service the requests.  Up to four 2500P-ECC1 modules can communicate

concurrently with a 2500 Series® controller.

Client requests to read data from the 2500 Series® controller are serviced from a data cache

maintained on the 2500P-ECC1 module. The frequency of cache updates is user configurable.

This data cache design allows protocols such as CAMP Server to provide rapid response to a high

volume of requests from SCADA workstations, HMI equipment, and operator panels while

providing a means to manage data quality.

The 2500P-ECC1 module supports the following communications protocols:

• CAMP Server

• CAMP Client

• Modbus Server

• Modbus Client

• Network Data Exchange

See CHAPTER 2 for information on these protocols.

Using a CTI-supplied configuration program, you can select the protocols to be used and

designate how they will operate. Configuration data is saved on a removable SD memory card,

located on the 2500P-ECC1 circuit board.  If a module ever fails, a replacement can quickly be

placed in service by transferring the SD card from the failed unit to the new one.

Client requests to read data from the 2500 Series® controller are serviced from a data cache

maintained on the 2500P-ECC1 module. The frequency of cache updates is user configurable.

This data cache design allows protocols such as CAMP Server to provide rapid response to a high

volume of requests from SCADA workstations, HMI equipment, and operator panels while

providing a means to manage data quality.

The 2500P-ECC1 Ethernet Communications Coprocessor module extends the communications

capabilities of CTI 2500 Series® controllers, offering increased connectivity and additional

protocols. By offloading the processing of communications protocols from the 2500 Series®

controller, the 2500P-ECC1 module minimizes the impact of network communications on

controller performance.
