The 1746-BTM module is compatible with any SLC processor that 

supports M0/M1 files, such as the SLC 5/05, SLC 5/04, SLC 5/03, and 

SLC 5/02 controllers.

Vocabulary

In this manual, we refer to:

• the barrel temperature control module as the “1746-BTM 

module,” the “BTM module,” or as “the module”

• the programmable controller as the “SLC processor”, or “the processor”

• a thermocouple as a “TC”

• a time-proportioned output as “TPO”

• the tuning-assisted processes as “TAP”

• proportional-integral-derivative as “PID”

• cold-junction compensation as “CJC”

Temperature Control Using a BTM Module in an SLC System

The temperature control module is an intelligent I/O module that can 

provide a maximum of 4 PID loops for temperature control. The 

module has 4 analog thermocouple (TC) inputs. Each analog input 

functions as the process variable (PV) for a PID loop. The PID 

algorithm and tuning–assisted–process (TAP) algorithm are performed 

on the module for each of the loops. The control–variable (CV) 

output of each loop, either analog output or time–proportioned 

output (TPO), is sent from the module to the SLC data table. Your 

application ladder logic must access the CV value in the data table and 

send the analog or TPO data to an output module to close the loop.

Features

This 4-axis position-control module has these features:

• Open-loop or closed-loop control

• Independent and coordinated axis control

• Position- and time-based control

• Accumulator push-out control

• Zero-scale/full-scale (offset & span) calibration for position inputs

• PID with anti-windup, bumpless parameter changes, setpoint weighting, and 

limited high-frequency derivative gain.

• Profile interpolation (linear or cubic spline) between setpoints

• Converging/diverging tooling (direct/reverse acting control)

• Three hold values per axis: manual position, purge, or die gap

• Independent profile scale and offset adjustments 

• Automatic parison weight adjustment

• Setpoint marking

Overview

The module performs its servo control task independently, but is dependent on the 

SLC processor for all of its configuration and run-time information. The processor 

may be also be used to supply process data or timing information over the 

backplane in certain situations (e.g. parison drop synchronization on continuous 

extrusion machines, or accumulator position in reciprocating screw machines).

The module uses a digital signal processor running a 

Proportional-Integral-Derivative (PID) algorithm to control four axes of motion. 

Four analog inputs and four analog outputs are used for process variables and 

signals, while four digital inputs and four digital outputs are used for start-of-drop 

synchronization and profile step synchronization signals, respectively. An excitation 

voltage is provided for use with linear potentiometers.

Communication with the SLC Processor

• shared memory

• control bit/status bit handshake

• micro processor

• PID control algorithm

• digital I/O

• analog I/O

The BASIC development software provides the user with a structured 

and efficient means to create BASIC programs for the module. This 

software is loaded into a an MS-DOS compatible personal computer. It 

uses the personal computer to facilitate editing, compiling 

(translating), uploading, and downloading of BASIC programs. 

The BASIC development software has a menu-driven, window-type 

environment that offers: 

• pull-down menus to access all editor functions.

• function key access to frequently used functions.

• multiple window editing.

• cut and paste support between windows.

• search and replace support.

• search between files support.

• built-in calculator that can paste results into your program.

• line draw editor to create operator interface images without having to enter ASCII characters.

• keystroke macros.

• undo and redo functions.

• extensive help messages for each menu, menu option, and for keywords embedded in the menu text.

• capability to create user-defined macro libraries.

• sophisticated debug tools including watch windows, single-step 

operation, and go to cursor breakpoint operation.

• syntax checked translations to native BASIC to reduce debug time.

• BASIC translator that steps through the BASIC program and identifies errors.

• ASCII terminal mode.

• hex file transfer support.

TIP

The 1746-BAS-T module is a higher-speed version of 

the 1746-BAS module with identical hardware 

features. The modules can be interchanged, except 

that the 1746-BAS-T module uses different (optional) 

memory modules. Due to the high speed of the 

1746-BAS-T module, existing programs written for 

the 1746-BAS module may require adjustment for 

identical operation using the faster 1746-BAS-T module.

Introduction

This application note demonstrates how to transfer ASCII data to an

SLC 5/02
or later processor by using a remote SLC 500 BASIC

module. An example shows how to transfer a maximum of 10

ASCII characters to an SLC 5/03 processor.

General Information

M-files cannot be accessed from a module in a remote I/O chassis.

Therefore, the BASIC module (Catalog Number 1746-BAS) is

limited to its 8 input and 8 output image words for data transfer

between itself and the SLC 5/02 or later processor. The first three

words of the I/O image are reserved for handshake bits, status, and

character count respectively. So, only 5 input and 5 output words are

available for actual data transfers. In addition, since a total of 8

words of image are used, they must be block transferred because

they do not fit in the image allocated in the Remote I/O Adapter

module (Catalog Number 1747-ASB).

To keep the BASIC programming to a minimum and the throughput

to a maximum, CALL 22 is used to transfer data from PRT1 on the

BASIC module to the SLC 5/03 processor in this case. CALL 22

operates on an interrupt basis, so the throughput of data from PRT1

to the backplane is 10 ms or less. To calculate overall throughput for

your specific system, consult your Remote I/O Adapter User Manual

(Publication 1747-6.13) and your Remote I/O Scanner User Manual

(Publication 1747-6.6).

If you also wish to transfer data from a SLC 5/02 or later processor

to a BASIC module in a remote I/O chassis, please refer to the

BASIC Language Reference Manual (Publication 1746-6.3) and

refer to the section on CALL 23.

Location

The Bulletin 1402 Line Synchronization Module (LSM) should be installed in a Bulletin 1771 I/O chassis that is located in a dry, 

dirt free environment away from heat sources and very high electric or magnetic fields. 

The module is designed to operate in an ambient temperature between 0 and 60° Celsius. 

The LSM is typically installed in a local rack in order to maximize data transfer rates.

Enclosure

This equipment is classified as open equipment and must be installed (mounted in an enclosure during operation as a means of providing safety protection. 

The enclosure chosen should protect the LSM from atmospheric contaminants such as oil, moisture, dust, corrosive vapors, or other harmful airborne substances. 

A steel enclosure is recommended to guard against EMI (Electromagnetic Interference) & RFI (Radio Frequency Interference). 

The enclosure should be mounted in a position that allows the doors to open fully. 

This will allow easy access to the wiring of the LSM and related components so that servicing is convenient. 

When choosing the enclosure size, extra space should be allowed for associated application equipment such as, transformers,

fusing, disconnect switch, master control relay, and terminal strips.

Mounting

The LSM mounts in two slots of a Bulletin 1771 Series B, I/O chassis. Mounting dimensions will vary with the size of the chassis selected. 

Refer to the appropriate 1771 literature for specific dimensions.

Power Supply

The LSM backplane power requirement is 1.1A at 5V DC. Refer to the appropriate 1771 literature for additional information on available power supply current.

Chassis Grounding

For correct and reliable performance, the grounding recommendations specified for Allen–Bradley PLC systems must be followed.

Swing Arm

The LSM requires the use of a Cat. No. 1771-WC (10 position, gold contacts) Swing Arm.

Chapter Objectives

After reading this chapter, you should be able to identify the product features and system applications.

Introduction

The Bulletin 1402, Line Synchronization Module (LSM), is designed to meet the needs of manufacturers, 

system integrators, and users of 3 phase alternators and cogeneration systems or for applications that require 

two three–phase systems to be synchronized with each other. 

The module provides means for automatic synchronization, load sharing, and high speed power system monitoring.

General Description

The Line Synchronization Module (LSM) is a two slot 1771 form factor module that fits into a standard Allen–Bradley 1771 I/O chassis. 

It performs three functions:

1. Measures appropriate parameters from the two three–phase systems and provides control and 

error signals to implement engine governor control for synchronization.

2. Provides an analog output that is representative of the ratio of the power being supplied by the alternator to the output rating of the alternator, 

reads an analog input that represents the ratio of the total system load being supplied to the total system capacity, 

and provides an error signal to adjust the alternator for proper load sharing based on the instantaneous load requirements.

3. Performs as a multi–function digital power monitor for the system.

These functions provide data and control signals which are communicated to the PLC-5 via the 1771 backplane.

Overview

The 1394 System 

The 1394 is a modular, multi-axis motion control and drive system family. 

Its unique design allows the 1394 to be used as an integrated motion controller and drive system (GMC) with Turbo or standard 

IMC S Class Compact functionality, an integrated 9/440 CNC system, 

a 9/Series CNC digital interface drive system, a SERCOS servo drive system, or an analog servo drive system.

All 1394 systems provide direct line connection (transformerless) for 360 and 480V three-phase input power, 

efficient IGBT power conversion, and slide-and-lock, module-to-module connection 

systems. Each system module can be configured with up to four axis modules, 

with each axis module interfacing to a motor. 

The 1394 provides significant panel space and interconnect savings.

1394 System Overview

GMC System

The 1394 GMC System provides all the functionality of the IMC S Class Compact Motion Controller and power conversion within the 1394 system module. 

Allen-Bradley offers two versions of the 1394 GMC system module (Standard GMC and GMC Turbo). 

Both systems are completely programmed and commissioned using GML (Graphical Motion Control Language),

offer Allen-Bradley DH485, RS-232, and RS-422 as standard communications, and have Remote I/O and AxisLink available as communication options.

The 1394x-SJTxx-C (Standard GMC) system supports four axis modules and provides four channels of auxiliary encoder input. 

The 1394C-SJTxx-L (Standard GMC) provides the same functionality of the 1394x-SJTxx-C, 

but supports only one axis module and provides two channels of auxiliary encoder input.
