CTI 2576 DeviceNet™ Scanner Module

The 2576 allows a 2500 Series® PLC to read I/O devices on a DeviceNet™ network.

The module provides one DeviceNet™ channel which can attach up to 63 network

devices. Multiple modules can coexist in the same I/O chassis.

Features

• DeviceNet™ points appear as a standard PLC I/O

• RS-232 serial port enables configuration of module and network devices

• Front panel LEDs allow monitoring of module and network devices

• Built-in power tap can be used to power DeviceNet™ network

Product Summary

The 2576 DeviceNet Scanner is a SIMATIC® 505

module that enables the PLC to access devices on a

DeviceNet network. The 2576 module writes data

supplied by the PLC to DeviceNet devices and obtains

data from these devices and presents it to the PLC as

standard I/O.

Since DeviceNet data appears to the PLC as standard

data types, no special PLC programming techniques are

required to access the DeviceNet devices. Using a CTI

supplied configuration program, the user can specify

how device data will appear to the PLC. Inputs from

the device may be mapped to X, WX, or V memory

locations. Outputs to the device may be mapped to Y,

WY, or V memory locations.

To maximize performance and provide maximum

flexibility, the 2576 logs into the PLC as two I/O slots -

a high-density I/O slot and a special function slot. The

high-density I/O interface provides 32 discrete-in (X),

32 discrete-out (Y), 32 word-in (WX) and 32 word-out

(WY) data points.  The Special Function interface can

transfer up to 480 words per PLC scan. It can also be

used by the PLC to send special commands to the module.

The module DeviceNet port can operate at baud rates

up to 500Kb.  A serial port provides a means to

download configuration record and software updates.

The front panel includes a complete set of LEDs that

display module and DeviceNet status.  The module also

includes a DeviceNet power tap, which allows the user

to connect a power supply to the network.
