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 or
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 upper
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.
g
SAFETY INSTRUCTIONS
Wiring Precautions
Completely turn off the external power supply when installing or
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, or
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.
g
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 solder
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 or
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.

Chapter 1. General
1.2. Features
1) MASTRER-K80S 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

5.2 Operation Processing
5.2.1 Operation Processing Method
1) Cyclic operation
A PLC program is sequentially executed from the first step to the last step, which is called scan. This sequential
processing is called cyclic operation. Cyclic operation of the PLC continues as long as conditions do not change fo
r interrupt processing during program execution. This processing is classified into the following stages:
Stages Processing
Operation Start
Initialization
Input image area refresh
Stage for the start of a scan processing. it is executed only o
ne time when the power is applied or reset is executed. It exe
cutes the following processing..
▶
I/O reset
▶
Execution of self-diagnosis
▶
Data clear
▶
I/O address allocation or t

Program ends
Output image area refresh
•The contents stored in the output image area is output to output par
when operation process ing of a program is fi nished.
END processing
•Stage for return processing after the CPU part has finished 1 sc
an. The END processing following processing is executed.
~ Self-diagnosis
~ Change the present values of timer and counter, etc.
~ Processing data communications between computer link module
and communications module.
~ Checking the switch for mode setting.
5-３
Chapter 5 CPU Module
2) Time driven interrupt operation method
In time driven interrupt operation method, operations are processed not repeatedly but at every pre-set interval. Interval, in the
MK80S series, can be set to between 0.001 to 6 sec. This operation is used to process operation with a constant cycle.
3) Event driven interrupt operation method
If a situation occurs which is requested to be urgently processed during execution of a PLC program, this operation
method processes immediately the operation, which corresponds to interrupt program. The signal, which informs
the CPU of those urgent conditions is called interrupt signal. The MK80S CPU has two kind of interrupt operation
methods, which are internal and external interrupt signal methods.
5.2.2 Operation processing at momentary power failure occurrence
The CPU detects any momentary power failure when the input line voltage to the power supply falls down below the defi ned value. When the CPU detects any momentary power failure, the following operations will be executed:
1) Momentary power failure within 20 ms
Input power
Momentary power failure
exceeding 2Oms
2) Momentary power failure exceeding 20 ms
Input power
Momentary power failure
exceeding 2Oms
(1) The operation processing is stopped with the output retained.
(2) The operation processing is resumed when normal status is restored.
(3) The output voltage of the power supply retains the defined value.
(4) The watchdog timer (WDT) keeps timing and interrupt timing normally
while the operations is at a stop.
The re-start processing is executed as the power is applied.
REMARK
1) Momentary power failure
The PLC defining power failure is a state that the voltage of power has been lowered outside the allowable
variation range of it. The momentary power failure is a power failure of short interval (several to tens ms).
5-４
Chapter 5 CPU Module
5.2.3 Scan Time
The processing time from a 0 step to the next 0 step is called scan time.
1) Expression for scan time
Scan time is the addition value of the processing time of scan program that the user has written, of the task program
processing time and the PLC internal processing time.
(1) Scan time = Scan program processing time + Interrupt program processing time + PLC internal processing time
• Scan program processing time = The processing time used to process a user program that is not specified to a ta
sk program.
• Interrupt program processing time = Total of the processing times of interrupt programs executed during one scan.
• PLC internal processing time = Self-diagnosis time + I/O refresh time + Internal data processing time + Communi
cations service processing time
(2) Scan time differs in accordance with the execution or non-execution of interrupt programs and communications
processing, etc.
2) Flag
Scan time is stored in the following system flag area.
z F50 : Maximum scan time (unit: 1 ms)
:
z F51
Minimum scan time (unit: 1 ms)
z F52 : Current scan time (unit: 1 ms)
5.2.4 Scan Watchdog Timer
1) Watchdog timer is used to detect a delay of abnormal operation of sequence program (Watchdog time is set in menu of basic
parameter of KGLWIN.)
2) When watchdog timer detects an exceeding of preset watchdog time, the operation of PLC is stopped immediately and al
l output is off.
3) If an exceeding of preset watchdog time is expected in sequence program, use ‘WDT’ instru ction. ‘WDT’ instruction make
elapsed watchdog time as zero.
4) In order to clear watchdog error, restarting the PLC or mode change to STOP mode are available.
REMARK
Setting range of watchdog : 1~ 6,000ms(unit : 10ms)

Chapter 5 CPU Module
5.2.5 Timer Processing
The MASTER-K series uses up count timers. There are 5 timer instructions such as on-delay (TON), off-delay (TOFF),
integral (TMR), monostable (TMON), and re-triggerable (TRTG) timer.
The measuring time range of 100msec timer is 0.1 ~ 6553.5 sec, and that of 10msec timer is 0.01 ~ 655.35 sec. Please
refer the ‘MASTER-K programming manual’ for details.
1) On delay timer
The current value of timer starts to increase from 0 when the input condition of TON instruction turns on. When the current
value reaches the preset value, the timer output relay turns on.
When the timer input condition is turned off, the current value becomes 0 and the timer output relay is turned off.

5.2.6 Counter Processing
The counter counts the rising edges of pulses driving its input signal and counts once only when the input signal is switched
from off to on. MASTER-K series have 4 counter instructions such as CTU, CTD, CTUD, and CTR. The maximum counter
setting value is hFFFF ( = 65535). The followings shows brief information for counter operation.
1) Up counter (CTU)
The counter output relay is turned on when the current value reaches the preset value. After the counter relay output is
turned on, the current value will increase until it reaches the maximum counting value (hFFFF = 65535).
When the reset input is turned on, the counter output relay and current value is cleared as 0.
2) Down counter (CTD)
When the CPU is switched to the RUN mode, the current value is set as preset value.

5.3.1 Classification of program
All functional elements need to execute a certain control process are called as a ‘program’. In MASTER-K series, a program is
stored in the RAM mounted on a CPU module or flash memory of a external memory module. The following table shows the
classification of the program.
Program type Description
The scan program is executed regularly in every scan. If the scan program is

not stored, the CPU cannot execute not only the scan program but also other
programs.
The TDI programs are executed with a constant time interval specified with
parameter setting.
The PDI programs are executed only external interrupt input is applied and
the corresponding interrupt routine is enabled by EI instruction.
The subroutine programs are executed when they are called by the scan
program with a CALL instruction.

Chapter 5 CPU Module
5.3.3 Interrupt function
When an interrupt occurs, the CPU module will stop the current operation and execute the corresponding interrupt routine.
After finish the interrupt routine, the CPU resume the sequence program from the stopped step.
MASTER-K series provides 2 types of interrupt. The TDI (Time driven interrupt) occurs with the constant period, and PDI
(Process driven interrupt) occurs with the status of external input.
Before to use interrupt function in sequence program, the parameter setting should be done properly. Then the
corresponding interrupt routine should be written after END instruction. (Refer chapter 4 for details ) If interrupt routines are
not matched with parameter settings, an error occurs and the operation of CPU will be stopped.
To execute an interrupt routine, use the EI instruction to enable the corresponding interrupt. The interrupt routine is not
executed if an interrupt factor occurs before execution of an EI instruction. Once an interrupt is enabled with EI instruction,
it keeps the enabled status until DI instruction is executed to disable the interrupt. When a CPU is turned to RUN mode, all
interrupts are disabled by default.
When multiple interrupt factors occur simultaneously, interrupt routines are executed according to the priority given to the
each interrupt. If an interrupt factor that has higher priority occurs while other interrupt that has lower priority are executing,
the interrupt routine of lower priority will be stopped and the interrupt of higher priority will be executed first. The following
figure shows how a CPU handles multiple interrupts.

1) parameter setting
2) Time driven interrupt
TDI occurs periodically with the constant interval assigned in parameter setting. The interrupt routine of TDI starts with the TDINT
instruction and ends with the IRET instruction.
When multiple interrupt factors occur simultaneously, interrupt routines are executed according to the priority given to the each interrupt.
If an interrupt factor has higher priority occurs while other interrupt of lower priority is executing, the interrupt routine of lower priority will
be stopped and the interrupt of higher priority will be executed first. Otherwise, two interrupts are executed consequently.
3) Process driven interrupt
Available PDI is P000 ~ P007 (8 points) assigned in parameter setting.
PDI occurs when the input status of P000 ~ P007 is changed from Off to On or from On to Off.

5.3.4 Error Handling
1) Error Classification
Errors occur due to various causes such as PLC system defect, system configuration fault or abnormal ope
ration result. Errors are classified into fatal error mode, which stops system operation for system stability, a
nd ordinary error mode, which continues system operation with informing the user of its error warning.
The main factors that occurs the PLC system error are given as followings.
• PLC hardware defect
• System configuration error
• Operation error during execution of the user programs
• External device malfunction
2) Operation mode at error occurrence
In case of error occurrence, the PLC system write the error contents the corresponding flags and stops or
continues its operation complying with its operation mode.
(1) PLC hardware defect
The system enters into the STOP state if a fatal error such as the CPU module defect has occurred, and
continues its operation if an ordinary error such as battery error has occurred.
(2) System configuration error
This error occurs when the PLC hardware configuration differs from the configuration defined in the
K80S series. The system enters into the STOP state.
(3) Operation error during execution of the user programs
It the numeric operation error of these errors occurs during execution of the user programs, its contents ar
e marked on the error flags and the system continues its operation. If operation time overruns the watchdo
g time or I/O modules loaded are not normally controlled, the system enters into the STOP state.
(4) External device malfunction
The PLC user program detects malfunctions of external devices. If a fatal error is detected the system ente
rs into the STOP state, and if an ordinary error is detected the system continues its operation.
REMARK
1) In occurrence of a fatal error the state is to be stored in the representative system error flags, and
an ordinary error in the representative system warning flags.
2) For details of flags, refer to Appendix 2. Flag List.

5.5 Functions
5.5.1 Self-diagnosis
1) Functions
(1) The self-diagnosis function permits the CPU module to detect its own errors.
(2) Self-diagnosis is carried out when the PLC power supply is turned on and when an error occurs the PLC i
s in the RUN
state. If an error is detected, the system stops operation to prevent faulty PLC operation.
2) WDT (Watch dog timer) function
The watch dog timer is an internal timer of a PLC to detect the error of hardware and a sequence program. The default
value is set as 200msec, and it is changeable with parameter setting. Refer the MASTER-K programming manual for
details on the parameter setting.
The CPU resets the watch dog timer before step 0 is executed (after the END processing is finished). When the END
instruction has not been executed within the set value due to an error occurred in the PLC or the long scan time of a
sequence program, the watch dog timer will times out. When a watch dog timer error is occurred, all outputs of the PLC are
turned OFF, and the ERR LED of the CPU will flashes. (RUN L ED will be turned OFF) Therefore, when use FOR ~ NEXT
or CALL instruction, insert WDT instruction to reset the watch dog timer.
3) Battery check function
When the voltage of the battery for back-up the memory IC of CPU are lower than the minimum back-up voltage, the BAT
LED of CPU module will be turned on.

5.5.2 I/O Force On/Off function
It is possible to input/output a designated data regardless of the result of program operation. This function is useful to check
operation of the input/output modules and wiring between the output modules and external devices.
1) Force On/Off setting method.
Force on/off setting is applied to input area and output area.
Force on/off should be set for each input and output, the setting operates from the time that Force I/O setting
enable’ is set.

Item Special Device
All Forced I/O enable M1910
Forced I/O enable by bit D4700 ~ D4731
Forced I/O set data D4800 ~ D4831
3) Force on/ off Processing timing and method
(1) Force Input
• After data have been read from input modules, at the time of input refresh the data of the junctions wh
ich have been set to force on/off will be replaced with force setting data to change the input image are
a. And then, the user program will be executed with real input data and force setting data.
(2) Force output
• When a user program has finished its execution the output image area has the operation results. At the
time of output refresh the data of the junctions which have been set to force on/off will be replaced w
ith force setting data and the replaced data will be output. However, the force on/off setting does not c
hange the output image area data while it changes the input image area data.
(3) Force on off processing area
• Input/output areas for force on/off setting are larger than the real I/O areas. If remote I/O is specified using
this area, the force on/off function is as just available in it as in the basic I/O areas.
(4) Precautions
• Turning the power off and on, changes of the operation mode or operation by reset switch (K1000S) do
es not change the previous force on/off setting data. They remain within the CPU module and operation
is executed with the same data.
• Force I/O data will not be cleared even in the STOP mode.
• If a program is downloaded or its backup breaks, the force on/off setting data will be cleared. The oper
ating program in memory differs from the program in the flash memory so that if operation restarts with
the program in the flash memory the on/off setting data will be also cleared.
• When setting new data, disable every I/O settings using the setting data clear’ function and set the new
data.
REMARK
1) For detailed operation, refer to the KGLWIN user’s Manual Chapter 7 ‘Force I/O setting.

Chapter 5 CPU Module
5.5.3 Direct I/O Operation function
This function is usefully available when an input junction state is directly read during execution of a program and used in the
operation, or the operation result is directly output to an output junction.
Direct input/output is executed by use of the ‘IORF’ instruction. If this instruction is used, the input/output image area will be
directly updated and applied to the continuing operations.
REMARK
1) For detailed operation, refer to the ‘MASTER-K Manual for instruction’.
5.5.4 System error history
When the system is stopped by error occurrence, the CPU stores the error occurrence time and error code to the special
data register area. The most recent 16 error occurring times and error codes are stored in the special data register.

b) Write RTC data
There is two ways to write new RTC data to the CPU.
The first one is using a handy loader (KLD-150S) or graphic loader (KGL-WIN). For detailed information, refer the
user’s manual of KLD-150S or KGL-WIN.
The second one is write sequence program. By switching a special bit on, user can replace the current RTC data
with the preset data stored in a specified memory area. The followings are the memory address of preset data and
an example program.

5) Wiring instructions
A high speed pulse input is sensitive to the external noise and should be handled with special care. When wiring the built-
in high speed counter of MK80S, take the following precautions against wiring noise.
(1) Be sure to use shielded twisted pair cables. Also provide Class 3 grounding.
(2) Do not run a twisted pair cable in parallel with power cables or other I/O lines which may generate noise.
(3) Before applying a power source for pulse generator, be sure to use a noise-protected power supply.
(4) For 1-phase input, connect the count input signal only to the phase A input; for 2-phase input, connect to phases A
and B.

When the EN input turns on, the counter starts counting pulse. When the EN is off, the counting is stopped and the current
value of high speed counter is cleared as 0.
2) U/D input (Up/down)
When the U/D input is off, the high speed counter operates as up counter. When the U/D is off, it operates as down-counter.
3) PR input (Preset)
When the PR input is on, the current value of high speed counted is replaced with the preset value (PV).
4) Output relay (F0170)
The F070 bit will be turn on when the current value of high speed counter (F18 : lower word, F19 : upper word) is equal of
greater than the set value (SV).

(7) The number of acceleration pulse
Automatically calculate at KGL-WIN if the maximum pulse and slop are set by user
Calculation method is as below
The number of acceleration pulse = [(maximum pulse – 50) / 50 +( maximum pulse – 100) / 50 + ············ +
(100 / 50) + (50 / 50) ] x acceleration slop x 2
ex) maximum pulse : 1000pps , acceleration slop : 1
The number of acceleration pulse = [(1000 – 50) / 50 + (900 – 50) / 50 + ············ +(100 /50 ) + (50 /50) ] x 1 x 2
= 380 (deceleration pulse is also 380)
(8) acceleration time
Automatically calculate at KGL-WIN if the maximum pulse and slop are set by user.
Calculation method is as below
acceleration time = [[(maximum pulse – 50) / 50] x acceleration slop x 10
ex) maximum pulse : 1000pps , acceleration slop : 1
acceleration time = [[(1000 – 50) / 50] x 1 x 10 = 380ms (deceleration time is also 380ms)
Remark
Acceleration slop and deceleration slop of MK80S pulse output are set up as the same. Set up proper value by the
sort of motor because if a/d slop increases, the arrival time to the designated max. Cycle also increases.

7) pulse out operation explanation
Condition 1)
Set up as acceleration slop = 1, max. frequency = 1000, no of pulse out = 5000.
← If as acceleration slop = 1, 1 pulse is output on the 1st step (velocity: 50pps).
Pulse velocity is 50pps, so time consuming is 20ms.
↑ 2 pulses are output on the 2nd step (velocity: 100pps) and time consumes 20ms
→ By calculation in the same way, the time to reach to 1000pps is
20ms x (20-1) = 380ms, and the no. of output pulses are 1+2+3...+18+19 = 190 units.
↓ Decreasing velocity inclination is 1, thus 190 units of pulses are needed.
° The no. of pulses in the uniform velocity region are 5000-190-190=4,620 units.

Condition 2
Set up as acceleration slop = 2, max. frequency = 1000, no of pulse out = 5000.
← If I/D velocity inclination is 2, 2 pulses are output on the 1st step(velocity: 50pps).
Pulse velocity is 50pps. So time consuming is 40ms.
↑ 4 pulses are output on the 2nd step(velocity: 100pps) and time consumes 20ms
→ By calculation in the same way, the time to reach to 1000pps is 40ms * (20-1) = 760ms,
and the no. of output pulses are 2+4+6...+36+38 = 380 units.
↓ Decreasing velocity inclination is 2, thus 380 units of pulses are needed.
° The no. of pulses in the uniform velocity region are 5000-380-380=4,240 units.

7.1.3. Pulse Catch Function
In the base unit, 8 points of pulse catch input contact points(P000 ~ P007) are internalized. Through using this contact
point short pulse signal, short as 0.2ms, can be taken which can not be executed by general digital input.
1) Usage
When narrow width of pulse signal is input, a trouble occurs which can not be detected by general digital input, so the
operation does not perform as user's intention. But in this case through pulse catch function even narrow interval of pulse
signal as 0.2ms min can be detected.
2) Operating Explanation
