Description

The 2590-A 16-point Isolated Discrete Output Module

provides sixteen discrete isolated outputs from the CTI

2500 Series®or Simatic® 505 I/O base. The module

uses solid- state output circuits to switch on or off ex

ternal devices such as pilot lamps, motor starters, or

solenoids. The 2590-A is designed to switch externally

supplied 20 to 132 VAC. The internal logic signals are

isolated from the external outputs to 1500 VDC.

Word and Discrete Mode

The 2585 may operate as a 16 Bit Word Input Module or as a 16 Dis

crete Input Module. By setting JP1 in Word Mode and using Workshop

to configure I/O the 2585 will look like a standard WX input module; for

example WX1-WX8.

NOTE: The 2585 will be mapped as the first WX address (i.e. WX1). In

Word Mode Channel 1 corresponds to bit 16 or LSB and Channel 16

corresponds to Bit 1 or MSB.

Note:

If the address line is blank or erroneous, re

check the module to ensure that it is firmly

seated in the slots. Generate the PLC I/O

configuration chart again. If the address

line is still incorrect, contact your local dis

tributor or CTI at 1-800-537-8398 for fur

ther assistance.

Changing Operating Modes

Any time the operating mode of the 2585 is

changed with JP1. the module must be con

figured in the PLC. Failure to do so may

cause unpredictable operation due to the

fact that the PLC uses different methods of

addressing discrete modules from word

modules.

Description

The 2585 16-Point TTL Input Module accepts sixteen

TTL driven inputs to the CTI 2500 SeriesTM or

Simatic® 505 Series I/O base. The inputs are

isolated channel-to-channel.

The 2585 has an input voltage range from 2.6 to 28

VDC; therefore, the inputs may be driven by CMOS

and open collector transistor devices.

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.

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
