1.2. Features
1) IMO-K7 series features
(1) Open network by us of communications protocol in compliance with international standard specifications.
(2) High speed processing with an operation-dedicated processor included.
(3) Various special modules that enlarge the range of application of the PLC
2) MK80S series is extremely compact, to fit a wide range of applications.
(1) High speed processing
High speed processing of 0.5μs/step with an operation-dedicated processor included.
(2) Various built-in functions
The main unit can perform many functions without using separate modules.
It is possible to construct various systems just using the main unit.
•Fast Processing Applications
-Pulse catch: Allows the main unit to read 4 inputs, each having a pulse width as small as 0.2ms
-High speed counter: Support high-speed counting up to 1 phase 16kHz, 2 phase 8kHz.
-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 15 ms.
•Using built-in pulse output without separate positioning module, it can control stepping motor or servo motor.
•Using RS-232C built-in port, it can connect with external devices, such as computers or monitoring devices and
communicate 1:1 with IMO-K7
•It has PID control function with which it can easily constitute a system without separate module.
(3) It can easily do On/Off of the system, using RUN/STOP switch.
(4) It can constitute various system, using separate Cnet I/F module.
(5) It can easily save the user program by simple manipulation in KGLWIN.
(6) Strong self-diagnostic functions
It can detect the cause of errors with more detailed error codes.
(7) It can prevent unintentional reading and writing, using password.

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

1.3 Terminology
The following table gives definition of terms used in this manual.
Terms Definition Remarks
Module
A standard element that has a specified function which configures the
system. Devices such as I/O board, which inserted onto the mother board
or base unit.
Example)
CPU module
Power Supply module
I/O module
Unit A single module or group of modules that perform an independent
Operation as a part of PLC system.
PLC system A system which consists of the PLC and peripheral devices. A user program
can control the system.
KGLWIN A peripheral device for the MASTER-K series. It executes program creation,
edit, compile and debugging(A computer software for Windows 95/98).
KLD-150S A hand-held loader used for program creation, edit, compile and debugging
for MASTER-K series.
I/O Image Area Internal memory area of the CPU module which used to hold I/O statuses.
Watch Dog Timer Supervisors the pre-set execution times of programs and warns if a
program is not completed within the pre-set time.
FAM Abbreviation of the word ‘ Factory Automation Monitoring S/W’ . It is used to
call S/W packages for process supervision.
Fnet Fieldbus network
Cnet Computer network(RS232C.RS422/485)
RTC Abbreviation of Real Time Clock. It is used to call general IC that
contains clock function.
