Chapter 1

Module Overview

This chapter describes the 1762sc-OF8 output module. The module provides 8

analog output channels that can be configured for current or voltage. Included is

information about:

General description

Input types and ranges

Data formats and filter frequencies

Hardware features

System overview and module operation

Section 1.1

General

Description The output module supports current and voltage type outputs. The module

converts the digital value stored in each channel’s output command word to an

analog current or voltage signal. Each output channel is individually configured

via software for a specific output type, data format, and provides open-circuit or

short-circuit detection and indication.

Section 1.2

Input Types

and Ranges The tables below list the output types and their associated ranges.

Voltage Selection

Range (VDC)

-10 V to +10 V

-11.0 to +11.0

Section 1.3

Data Formats For each module, the data can be configured for:

Engineering units

Scaled-for-PID

Raw/proportional data

Percent of full range

Section 1.4

Hardware

Features

Module configuration is done via the controller’s programming software. The

module configuration is stored in the memory of the controller. Refer to your

controller’s user manual for more information. The illustration below shows the

module’s hardware features.

1.4.1 LED Indicator

The 1762 output module uses a single green LED to show operational status of

the module. The LED will illuminate solid when the PLC is in run mode and the

module properly configured. If the module is not properly configured, or if the

PLC is not in run mode, the LED will blink rapidly. The following blink codes

are the only exception:

Table 1-1 (LED Blink Codes)

Blink Code

Description

PLC not in run mode, or no valid module configuration present

Solid

Module is in run mode (Normal Operation)

Factory calibration in progress

Factory calibration invalid

Module is in command mode

Section 1.5

System

Overview The module communicates to the controller through the bus interface. The

module also receives 5 VDC and 24 VDC power through the bus interface.

1.5.1 Module Power-up

At power-up, the module performs a check of its internal circuits, memory, and

basic functions. During this time, the module status LED remains off. If no

faults are found during power-up diagnostics, the module status LED blinks

rapidly waiting for command mode.

After power-up checks are complete, the module waits for command mode and

then valid channel configuration data. If an invalid configuration is detected, the

module generates a configuration error and remains in command mode. Once the

module is properly configured and enabled, it continuously converts the output

command value to a proportional analog output signal.

Each time a channel command value is read by the output module, that data value

is tested by the module for an over-range or under-range condition. If such a

condition is detected, a unique bit is set in the channel status word. The channel

status word is described in section 0 Input Data File.

Using the module image table, the controller reads the two’s complement binary

converted input data from the module. This typically occurs at the end of the

program scan or when commanded by the control program. If the controller and

the module determine that the data transfer has been made without error, the data

is used in the control program.

All outputs are disabled until the PLC goes into run mode, and the module receives a valid configuration.

1-4 Chapter 1: Module Overview

User’s Manual Pub. 0300246-01 Rev. C

1.5.2 Module Operation

When the module receives a new command value from the output image, the

module’s circuitry converts the digital value to an analog current/voltage signal

using a DAC (Digital to Analog Converter). See the block diagram below.
