쎲

Observe all safety and accident prevention regulations applicable to your spe-

cific application. Installation, wiring and opening of the assemblies, compo-

nents and devices may only be performed with all power supplies discon-

nected.

쎲

Assemblies, components and devices must always be installed in a shock-

proof housing fitted with a proper cover and protective equipment.

쎲

Devices with a permanent connection to the mains power supply must be inte-

grated in the building installations with an all-pole disconnection switch and a

suitable fuse.

쎲

Check power cables and lines connected to the equipment regularly for breaks

and insulation damage. If cable damage is found, immediately disconnect the

equipment and the cables from the power supply and replace the defective ca-

bling.

쎲

Before using the equipment for the first time check that the power supply rating

matches that of the local mains power.

쎲

Residual current protective devices pursuant to DIN VDE Standard 0641 Parts

1-3 are not adequate on their own as protection against indirect contact for in-

stallations with positioning drive systems. Additional and/or other protection

facilities are essential for such installations.

쎲

EMERGENCY OFF facilities pursuant to EN 60204/IEC 204 VDE 0113 must re-

main fully operative at all times and in all control system operating modes. The

EMERGENCY OFF facility reset function must be designed so that it cannot

cause an uncontrolled or undefined restart.

쎲

You must also implement hardware and software safety precautions to prevent

the possibility of undefined control system states caused by signal line cable

or core breaks.

쎲

All relevant electrical and physical specifications must be strictly observed

and maintained for all the modules in the installation.

1 Introduction

The most important characteristics of the MELSEC ST series are summarized in this installation

description. This description is designed to help the experienced user quickly start-up the mod-

ules. Additional information and a detailed mounting and wiring description is in the MELSEC ST

series operating manual. This documentation is provided solely as a quick reference.

1.1 General Description

The MELSEC ST series is a modular input and output system which is connected as slave sta-

tion to a PROFIBUS/DP network. An ST series station consists of

쎲a head station to which the PROFIBUS is connected.

쎲Power supply modules.

쎲Digital and analog I/O modules.

The I/O modules can be combined as desired according to the requirements.

1.2 Special Features

Reduced wiring effort

– External voltages

for supplying sensors and actuators are connected to the power distribution modules of

the ST series only.The other system modules are supplied with power via internal connec-

tions. Wiring requirements are significantly reduced because the supply voltage does not

need to be connected to each individual module.

– PROFIBUS connection

Only the head station is connected to the PROFIBUS/DP network.

–Connection of the I/O modules

Peripherals are connected either via spring clamp terminals, (into which the wires are just

inserted), or via conventional screw clamp terminals.

Flexible System Set-up

The number of inputs and outputs can be adapted easily to the application. Digital modules with

2, 4, and 16 inputs, and with 2 and 16 outputs are available. Up to 63 I/O modules (max. 26 ana-

log I/O modules) can be connected to one head module.

Simple Service

The electronics modules are plugged into a base module to which the peripheral signals are

connected. The base module is mounted on a DIN rail. Electronic modules can be replaced in

operation. No tool is required to do this. The GX Configurator DP is available to configure the

system.

Introduction

MELSEC ST Series 7

1.3 System Configuration

1.3.1 Overview

A slave station set-up with the MELSEC ST series is connected to a PROFIBUS/DP network.

Use is not limited to networks with a MELSEC PLC as master station, but is also possible in net-

works with devices from “third-party” manufacturers.

Populating the stations with ST modules is based on the requirements of the application. Analog

modules for capture or output of voltages or currents are available, in addition to digital input and

output modules.

“ST” means “Slice Type terminal”, and refers to the narrow width of the modules (only 12.6 mm!).

In addition to the narrow modules, cost-saving modules with 16 digital inputs or outputs are also

available.

An ST series slave station always consists of a head station, which establishes the connection

to the PROFIEBUS/DP network. At least one power distribution module, and the digital and/or

analog I/O modules are connected to the head station.

The I/O modules consist of an electronics module and a base module, which establishes the

connection to the head station via screw clamp terminals, or spring clamp terminals. The elec-

tronics modules are simply plugged onto the base module, which in turn is mounted on a DIN

rail. It is not necessary to disconnect the wiring when swapping out a module because the sig-

nals are connected to the base module.

1.3.2 Components of the MELSEC ST Series

NOTE A base module is required for mounting each ST series electronics module, except for the

head station.

*Base modules with screw clamp terminals and base modules with spring clamp terminals

cannot be used together in one system. Use either one of them.

1.3.3 Notes on System Setup

Operation of the ST1PSD power distribution module is possible in two different modes: In “H”

mode, 24 V DC is made available to supply the head station and the I/O modules, as well as 5 V

DC for the backplane bus. In “R” mode only the internal backplane bus is supplied with 5 V DC.

The mode (H or R) is selected by using different base modules that are identified by the letters

“H” or “R” in the type designation.

At least one ST1PSD is required in “H” mode in order to operate an ST series station. This is

installed on the right side of the head station. Additional power supplies ( with the “R” base mod-

ule) are only required if power consumption of the installed ST modules exceeds the capacity a

single power distribution module.

The ST1PDD power feeding module supplies the connected actuators and sensors with a 24 V

direct current.

Use voltages from different sources to connect to the module’s “SYS” and “AUX” terminals. If

multiple ST1PSD are used, then all “SYS” voltage inputs must be supplied by the same power

source.

The power distribution modules and power feeding modules are not overload-protected. It is

strictly required to provide fuses between power supply and module.

Analog modules must be separately supplied with power. Use an ST1PDD to separate the

power supply of digital and analog modules. The ST1PDD is mounted on the DIN rail to the left of

the modules that it will supply.

The DIN rail on which the modules are mounted must be conductive.
