Safety Instructions
Design Precautions
Warning
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 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.

4.2 Operation Processing
4.2.1 Operation Processing Method
1) Cycle 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 option card continues as long as conditions
do not change for interrupt processing during program execution. This processing is classified into the following
stages:
Stages
Processing
Operation Start
-
Stage for the start of a scan processing. It is executed only one
Initialization
time when the power is applied or reset is executed. It executes
the following processing.
▶ I/O reset
▶ Execution of self-diagnosis
▶ Data clear ▶ Allocating I/O address and type
Input Image Area Refresh
Input conditions are read and stored into the input image area
before it starts processing.
Program operation processing
Program starts
Program is sequentially executed from the first step to
the last step Program operation processing.
Program ends
Output image area refresh
The contents stored in the output image area is output to output
part when operation processing of a program is finished.
END processing
Stage for return processing after the CPU part has finish
ed 1 scan.
The END processing following processing is executed.
▶ Self-diagnosis
▶ Change present values of timer and counter, etc.
▶ Processing data communications between computer
link module and communications module.
▶ Checking the switch for mode setting.
2) Interrupt operation method
If a situation occurs which is requested to be urgently processed during execution of a PLC progra
m, this operation method processes immediately the operation, which corresponds to interrupt progr
am. The signal, which informs the CPU of those urgent conditions is called interrupt signal. The C
PU has two kinds of interrupt operation methods, which are internal and external interrupt signal me
thods.

4.2.2 Operation Processing at Momentary Power Failure Occurrence
The momentary power failure occurs when the input line voltage to the power supply falls down
below the rated voltage. When momentary power failure occurs within 10ms, the PLC option card
maintain operation processing. But if it exceeds 10ms, PLC option card stops processing and all
output turns off. And The re-start process is executed as the power is re-applied.
1) Momentary power failure within 10 ms
→ The operation processing is maintained.

Remark
1) Momentary power failure
The PLC option card 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).
4.2.3 Scan Time
The processing time from a 0 step to the 0 step of next scan is called scan time.
1) Expression for scan time
Scan time is the sum of the processing time of scan program that the user has written, of the
task program processing time and the PLC option card internal processing time.
(1) Scan time = Scan program processing time + Interrupt program processing time +
PLC option card internal processing time
• Scan program processing time = The processing time used to process a user program
that is not specified to a task program.
• Interrupt program processing time = Total of the processing time of interrupt programs
executed during one scan.
• PLC option card internal processing time = Self-diagnosis time + I/O refresh time + Int
ernal data processing time + Communications service proc
essing time
4-3
Chapter 4 CPU Function
(2) Scan time differs in accordance with the execution or non-execution of interrupt progr
ams and communication processing, etc.
2) Scan time monitoring
Scan time is stored in the following system flag area.
• F50 : Maximum scan time (unit: 1 ms)
• F51 : Minimum scan time (unit: 1 ms)
• F52 : Current scan time (unit: 1 ms)
4.2.4 Scan Watchdog Timer
1) Watchdog timer is used to detect a delay which is attributable to 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 P
LC option card is stopped immediately and all output is off.
3) If an exceeding of preset watchdog time is expected in sequence program, use ‘WDT’
instruction. ‘WDT’ instruction makes elapsed watchdog time to zero.
4) In order to clear watchdog error, restart the PLC option card or change mode to STOP.
Remark
- Setting range of watchdog : 10 ~ 6,000ms (unit : 10ms)
4.2.5 Timer Processing
The PLC option card use up count timer. There are 5 timer instructions such as On-delay
Timer (TON), Off-delay Timer (TOFF), Integral (TMR), Monostable (TMON), Retreggerable
(TRTG). The measuring range of 100msec timer is 0.1 ~ 6553.5 seconds, 10msec timer is
0.01 ~ 655.35 seconds.

4.2.6 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. PLC option card have 4 counter instructions
such as Up Counter (CTU), Down Counter(CTD), Up/Down Counter (CTUD), and Ring
Counter (CTR). The followings shows brief information for counter operation.
• Up Counter (CTU) increases the current value.
• Down Counter (CTD) decreases the current value.
• Up/Down Counter (CTUD) compares the 2 input conditions’ value.
• Ring Counter (CTR) clear the current value as 0 when current value reaches to set value by
increasing the current value.
1) Current value update and Contact On/Off
(1) Up Counter
• Input Condition (U), Reset Condition (R), and preset value must be existed.

4.3.4 Error Handling
1) Classification of Errors
Errors occur due to various causes such as PLC option card system defect, system configuration
fault or abnormal operation result. Errors are classified into fatal error mode, which stops system
operation for system stability, and ordinary error mode, which continues system operation with inf
orming the user of its error warning.
The main factors that occurs the PLC option card error are given as followings.
• PLC option card 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 option card write the error contents the correspond
ing flags and stops or continues its operation complying with its operation mode.
(1) PLC option card hardware defect
The system enters into the STOP state if a fatal error such as the CPU module def
ect has occurred, and continues its operation if an ordinary error such as operation
error has occurred.
(2) System configuration error
This error occurs when the PLC option card hardware configuration differs from the c
onfiguration defined in the PLC option card. 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 pr
ogram, its contents are marked on the error flags and the system continues its oper
ation. If operation time overruns the watchdog time or I/O modules loaded are not n
ormally controlled, the system enters into the STOP state.
(4) External device malfunction
The PLC option card user program detects malfunctions of external devices. If a fatal
error is detected the system enters into the STOP state, and if an ordinary error is
detected the system continues its operation.
Remark
1) In occurrence of a error, the state is to be stored in the representative system error
flag F006.
2) For details of flags, refer to Troubleshooting.

1) Function
(1) The self-diagnosis function permits the CPU module of PLC option card to detect its own errors.
(2) Self-diagnosis is carried out when an error occurs during PLC option card power supply is turne
d on or operating process. If an error is detected, the system stops operation to prevent faulty
PLC option card operation.
2) Watchdog Timer
The watch dog timer is an internal timer of a PLC option card to detect the error of hardware and a
sequence program. it is changeable with 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 option card or the delay of a sequence program, the watch dog timer will times out. When a
watch dog timer error is occurred, all outputs of the PLC option card are turned OFF, and the ERR
LED of the CPU will flickers. (RUN LED will be turned OFF) Therefore, when use FOR ~ NEXT or

(1) Forced Input
After data have been read from input modules, at the time of input refresh the data of
the junctions which
have been set to force on/off will be replaced with force setting d
ata to change the input image area. 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 operatio
n results. At the time of output refresh the data of the junctions which have been set to
force on/off will be replaced with force setting data and the replaced data will be output.
However, the force on/off setting does not change the output image area data while it c
hanges the input image area data.

(6) Terminal output (P40~P43 terminals of TB1 in the outline drawing)
This product provides total 4 terminal output contacts (4 relay contacts) which are P40~P43 on the TB1.
Connection method is as shown below.
Load
1) Output functions of PLC option under inverter LV (low voltage) trip (default)
When the iS7 inverter is tripped by LV(low voltage), the contacts which have been ON remain the
ON status.
When the iS7 inverter is fully discharged and the power supply to the control board of this product is
cut-off, the outputs from the contact points become OFF. (Note: larger iS7 inverter capacity gives
longer time from LV trip to power supply cut-off to the control board).
The above describes the default specifications of this product.
2) Output functions of PLC option under inverter LV (low voltage) trip (application)
If the inverter has large capacity, the time elapsed form the inverter’s LV trip to the power supply to
the control board of this product is cut-off is relatively long, e.g., 10 or more seconds. Therefore,
according to the requirement of the installation, the output contacts of this product may have to be
isolated before the said time. The method of cutting off the output of this product at the time of LV
trip of inverter is described in page 7-27~28.
(7) Terminal resistance for RS485 communication (J2 in the outline drawing)
If the J2 jumper is set to ON, terminal resistance of 120 ohm is inserted between the internal
communication (Modbus-RTU) lines (S+, S-). When this product is installed at the terminal of a
communication system, set the terminal resistance jumper J2 to ON. This will adjust the impedance
between the communication lines to improve the distortion and attenuation of the RS485 communication
signals caused by the delay in data transmission.

4) Battery discharge check
Turn on the power of this product. Go to No. 73 (Real Time) in the CNF group of the iS7 inverter using
the loader of the iS7. If the present time is “2000/01/01 00:00,” the battery needs to be replaced.
The same will be displayed at power turn OFF/ON if no battery is installed.
5) Battery replacement
- Turn the power supply of the iS7 inverter to OFF.
- Remove iS7 inverter cover. Remove the cover of this product, too.
- Remove discharged battery carefully.
- Insert a new battery and push it down with a thumb.
- Turn on the power of the iS7 inverter.

Chapter 8 Modbus Communication
8.1 Modbus Communication
8.1 Introduction
PLC option card of iS7 inverters’ built-in communication supports Modbus, the Modicon
product’s communication protocol. It supports ASCII mode, using ASCII data and RTU mode
using Hex data. Function code used in Modbus is supported by instruction and especially
function code 01, 02, 03, 04, 05, 06, 15 and 16. Refer to "Modicon Modbus Protocol Reference
Guide"
8.1.2 Basic Specification
1) ASCII Mode
(1) It communicates, using ASCII data.
(2) Each frame uses ': (colon: H3A)', for header, CRLF (Carriage Return-Line Feed : H0D
H0A), for tail.
(3) It allows Max. 1 second interval between characters.
(4) It checks errors, using LRC.
(5) Frame structure (ASCII data)

2) RTU mode
(1) It communicates, using hex data.
(2) There's no header and tail. It starts with address and finishes frame with CRC.
(3) It has at least 3.5 character times between two frames.
(4) It ignores the current frame when 1.5 character times elapse between characters.
(5) It checks errors, using 16 bit CRC.
(6) Frame structure (hex data)
Item

Size
1 byte
1 bytes
n bytes
2 bytes
Remark
1) The size constituting 1 letter is 1 character. So 1 character is 8 bits that is 1 byte.
2) 1 character time means the time lapsed for sending 1 character.
Ex) Calculation of 1 character time at 1200 bps.
1200 bps means that it takes 1 second to send 1200 bits.
To send 1 bit, 1 sec/1200 bits = 0.83 ms.
Therefore, 1 character time is 0.83ms * 8 bits = 6.64ms.
3) 584, 984 A/B/X executes frame division, using intervals of more than 1 sec without LRC
in processing internally.
8-1
Chapter 8 Modbus Communication
3) Address area
(1) PLC option card supports 0 to 31.
4) Function code area
(1) PLC option card supports only 01, 02, 03, 04, 05, 06, 15, and 16 among Modicon products’
function code.
(2) If the response format is Confirm+(ACK), it uses the same function code.
(3) If the response format is Confimr-(NCK), it returns as it sets the 8th bit of function code as 1.
Ex) If function code is 03,
- Only function code is written here because only function codes are different.
[Request]
0000 0011 (H03)
[Confirm+]
0000 0011 (H03)
[Confirm-]
1000 0011 (H83)
It returns as it sets the 8th bit of
function code of request frame.
5) Data area
(1) It sends data, using ASCII data (ASCII mode) or hex (RTU mode).
(2) Data is changed according to each function code.
(3) Response frame uses data area as response data or error code.
6) LRC Check/CRC Check area
(1) LRC (Longitudinal Redundancy Check): It works in ASCII mode. It takes 2 complement from sum
of frame except header or tail to change into ASCII code,
(2) CRC (Cyclical Redundancy Check): It works in RTU mode. It uses 2-byte CRC check rules.
Remark
1) All numerical data can use hexadecimal, decimal, and binary type. If we convert decimal 7
and 10 into each type:
Hexadecimal: H07, H0A or 16#07, 16#0A
Decimal: 7, 10
Binary: 2#0111, 2#1010

8) Modbus addressing rules
PLC option card starts its address from 0 and matches with 1 of Modicon products' data address. So
PLC option card address n matches n+1 of Modicon products' address. This means that the output
contact point 1 (0001) of Modicon products is marked as communication address 0 and the input
contact point 1 (0001) of Modicon products is marked as communication address 0 in PLC option card.
9) The size of using data
As for data size, PLC option card supports 128 bytes in ASCII mode and 256 bytes in RTU mode. The
maximum size of the Modicon products is different from each other’s kind. So refer to "Modicon
Modbus Protocol Reference Guide."

Chapter 10 Troubleshooting
The following explains contents, diagnosis and corrective actions for various errors that can occur during system
operation.
10.1 Basic Procedures of Troubleshooting
System reliability not only depends on reliable equipment but also on short downtimes in the event of
faults.
The short discovery and corrective action is needed for speedy operation of the system. The following
shows the basic instructions for troubleshooting.
1) Visual checks
Check the following points.
• Machine operating condition (in stop and operating status)
• Power On/Off
- Status of I/O devices
- Condition of wiring (I/O wires, extension and communications cables)
- Display states of various indicators (such as POWER LED, RUN LED, ERR. LED and I/O
LED).
After checking them, connect peripheral devices and check the operation status of the PLC
option card and the program contents.
2) Trouble Check
Observe any change in the error conditions during the following.
• Switch to the STOP position, and then turn the power on and off.
3) Narrow down the possible causes of the trouble where the fault lies, i.e.:
• Inside or outside of the PLC?
• I/O module or another module?
• PLC option card program?
