This s

mbol indicates the possibility of

injury or damage to property.

■ The meaning of each symbol in this manual and on your equipment is as follows

This is the safety alert symbol. Read and follow instructions carefull situation.

to avoid dangerous

This s

mbol alerts the user to the presence of “dangerous

voltage” inside the product that mi

ht cause harm or electric

shock.

SAFETY INSTRUCTIONS

Design Precautions

 Install a safety circuit external to the PLC that keeps the entire system

safe even when there are problems with the external power supply o the PLC module. Otherwise, serious trouble could result from erroneous output or erroneous operation.

- Outside the PLC, construct mechanical damage preventing interlock circuits such as emergency stop, protective circuits, positioning uppe and lower limits switches and interlocking forward/reverse operation. When the PLC detects the following problems, it will stop calculation and turn off all output in the case of watchdog timer error, module interface error, or other hardware errors. However, one or more outputs could be turned on when there are problems that the PLC CPU cannot detect, such as malfunction of output device (relay, transistor, etc.) itself or I/O controller. Build a fail safe circuit exterior to the PLC that will make sure the equipment operates

Warnin

safely at such times. Also, build an external monitoring circuit that will monitor any single outputs that could cause serious trouble.

 Make sure all external load connected to output does NOT exceed the

rating of output module.

Overcurrent exceeding the rating of output module could cause fire, damage or erroneous operation.

 Build a circuit that turns on the external power supply when the PLC

main module power is turned on.

If the external power supply is turned on first, it could result in erroneous output or erroneous operation.

SAFETY INSTRUCTIONS

Design Precautions

 Do not bunch the control wires or communication cables with the main

circuit or power wires, or install them close to each other. They should be installed 100mm (3.94inch) or more from each other.

Not doing so could result in noise that would cause erroneous operation.

Caution

Installation Precautions

Caution

 Use the PLC in an environment that meets the general specification

contained in this manual or datasheet.

Using the PLC in an environment outside the range of the general specifications could result in electric shock, fire, erroneous operation, and damage to or deterioration of the product.

 Completely turn off the power supply before loading or unloading the

module.

Not doing so could result in electric shock or damage to the product.

 Make sure all modules are loaded correctly and securely.

Not doing so could cause a malfunction, failure or drop.

 Make sure I/O and extension connector are installed correctly.

Poor connection could cause an input or output failure.

 When install the PLC in environment of much vibration, be sure to

insulate the PLC from direct vibration.

Not doing so could cause electric shock, fire, and erroneous operation.

 Be sure to there are no foreign substances such as conductive debris

inside the module.

Conductive debris could cause fires, damage, or erroneous operation.

SAFETY INSTRUCTIONS

Wiring Precautions

 Completely turn off the external power supply when installing o

placing wiring.

Not doing so could cause electric shock or damage to the product.

 Make sure that all terminal covers are correctly attached.

Not attaching the terminal cover could result in electric shock.

Warnin

Caution

 Be sure that wiring is done correctly be checking the product’s rated

voltage and the terminal layout.

Incorrect wiring could result in fire, damage, or erroneous operation.

 Tighten the terminal screws with the specified torque.

If the terminal screws are loose, it could result in short circuits, fire, o erroneous operation.

 Be sure to ground the FG or LG terminal to the protective ground

conductor.

Not doing so could result in erroneous operation.

 Be sure there are no foreign substances such as sawdust or wiring

debris inside the module.

Such debris could cause fire, damage, or erroneous operation.

SAFETY INSTRUCTIONS

Startup and Maintenance Precautions

 Do not touch the terminals while power is on.

Doing so could cause electric shock or erroneous operation.

 Switch all phases of the external power supply off when cleaning the

module or retightening the terminal or module mounting screws.

Not doing so could result in electric shock or erroneous operation.

 Do not charge, disassemble, heat, place in fire, short circuit, or solde

the battery.

Mishandling of battery can cause overheating or cracks which could result in injury and fires.

 Do not disassemble or modify the modules.

Doing so could cause trouble, erroneous operation, injury, or fire.

 Switch all phases of the external power supply off before mounting o

removing the module.

Not doing so could cause failure or malfunction of the module.

 Use a cellular phone or walky-talky more than 30cm (11.81 inch) away

from the PLC

Not doing so can cause a malfunction.

Warnin

Caution

Disposal Precaution

 When disposing of this product, treat it as industrial waste.

Not doing so could cause poisonous pollution or explosion.

Chapter 1 General

1.2. Features

1) MASTER-K120S series is extremely compact, to fit a wide range of applications and have following features.

(1) High speed processing

High speed processing of 0.1~0.9µs/step with an general purpose processor included .

(2) Various built-in functions

The main unit can perform many functions without using separate modules. Therefore, It is possible to construct various systems just using the main unit.

• Fast Processing Applications

- Pulse catch: Allows the main unit to read a pulse which has width as small as 10 ㎲.

- High speed counter(Economic): Support high-speed counting up to 100(10)kHz for 1 phase, 50(5)kHz for 2 phase.

- External interrupts : Using in applications that have a high-priority event which requires immediate responses.

• The input filter function help reduce the possibility of false input conditions from external noise, such as signal chattering. The filter time can be programmed from 0 to 1000ms.

• Using RS-232C and RS-485 built-in port, MASTER-K120S can connects with external devices, such as personal computers or monitoring devices and communicate 1:N with MASTER-K120S system.

• Using built-in PID control function, PID control system can be constructed without using separate PID module.

• Using built-in Positioning function, position control system can be constructed without using separate position control

module.(only DRT/DT type has built-in positioning function)

(3) Battery-less

The user’s program can be saved permanently, because it is stored to EEPROM.

(4) When program is edited during processing, it is stored to EEPROM automatically

(5) Open network by use of communication protocols in compliance with international standard specifications. (6) Various special modules that enlarge the range of application of the PLC (7) It can easily do On/Off of the system, using RUN/STOP switch.

(8) It can easily save the user program in EEPROM by simple manipulation in KGLWIN without using external memory. (9) Strong self-diagnostic functions It can detect the cause of errors with more detailed error codes. (10) It can prevent unintentional reading and writing, using password.

(11)

Debugging function(Standard type)

On-line debugging is available when the PLC Operation mode is set to debug mode. y executed by one command. y executed by break-point settings. y executed by the condition of the device y executed by the specified scan time. (12) Various program execution function External and internal interrupt program as well as scan program can be executed by setting the execution condition. Therefore, user can set variously program execution mode.

2.1.2 Cnet I/F system

Cnet I/F System is used for communication between the main unit and external devices using RS-232C/RS-422 Interface.

The MK120S has a built-in RS-232C port, RS-485 port and has also G7L-CUEB for RS-232C, G7L-CUEC for RS-422. It is possible to construct communication systems on demand.
