Function Block Diagram

1.1 Function Block Diagram

How I/O data are transferred to/from the inverter by the built-in PLC function is explained using function blocks. (1) I/O data read, write, etc. can be performed by accessing the inverter in the

predetermined method using special relays, special registers, etc.

(2) Operation, parameter read/write, etc. can be performed in accordance with the

created sequence programs (built in the inverter) using input data from the control input terminals. With the output signals, output data can be output to outside the inverter from the control output terminals as not only the inverter's status signals but also pilot lamp on/off, interlock and other control signals set freely by the user.

PLC FUNCTION

Prior to Sequence Program Creation

1.5 Prior to Sequence Program Creation

1.5.1 Precautions for sequence program creation

POINT

•Online change of the sequence program and access to other stations are not

allowed. In addition, program read/write from other stations and all PLC memory clear cannot be performed.

•Back up the ladder configured with the protective function of GX Developer.

If any of the instructions (refer to page 103) and devices (refer to page 3) that cannot be used with the built-in PLC function exists in a sequence program, an instruction code error occurs at the execution of that instruction. Error code D9008=10 Operation error step D9010

D9011

REMARKS

•Refer to page 22 for the error codes.

1.5.2 Usable main GX Developer functions

z Parameter or sequence program read/write z Ladder monitor z Device monitor z Device test z All device memory clear z Remote RUN/STOP

CAUTION

Device test ([Online] - [Debug] - [Device test]) of GX Developer can be performed, but if devices corresponding to control terminal (e.g. STF, STR) signals are tested, the devices turn on in the sequence but the inverter does not perform the corresponding operation.

Prior to Sequence Program Creation

1.5.3 Sequence program execution key

The sequence program execution key (STOP/RUN) of the PLC is switched by turning off/on the SQ signal.

POINT

•For the terminal used for SQ signal input, set "50" in any of Pr.178 to Pr. 189 to

assign the function.

•SQ-SD must be shorted to execute the built-in PLC function.

CAUTION

If the SQ signal is not turned on, the start signal of the inverter is designed to become valid by the factory setting of

Open (STOP) the SQ signal-SD terminals when writing a sequence program, for example. When executing the sequence program, short (RUN) the SQ signal-SD terminals. Remote run/stop of the built-in PLC function can be executed in any of the following methods:

• Setting using the built-in PLC function parameter (contact)

• Using GX Developer

• Via CC-Link communication (refer to page 49)

REMARKS

•The validity limit of the SQ signal can be controlled using Pr.415 Inverter operation lock mode

setting. (Refer to page 43.)

CAUTION

The outputs (Y) are cleared by turning the SQ signal off (STOP) after sequence program execution (SQ signal on). The other devices retain the device data prior to STOP. When you want to clear the remaining device data, power off or reset (short RES-SD for 0.1s, then open) the inverter.

Pr.415 Inverter operation lock mode setting.

PLC FUNCTION

Prior to Sequence Program Creation

1.5.4 Sequence program write

POINT

Sequence program write can be performed in any operation mode.

When rewriting the PLC function parameters and sequence program using GX Developer, check the following:

1)Check that the sequence program execution key is in the STOP position (SQ signal is off) (refer to page 7).

2)Check that the inverter is at a stop.

3)Check that the communication specification setting parameters (Pr.117 to Pr.124) are set correctly. If any of these parameters is set incorrectly, communication with GX Developer cannot be made.

REMARKS

Check and set the communication specification parameter (Pr. 117 to Pr. 124) using the parameter unit (FR-PU04/FR-PU07). (Refer to the FR-PU04/FR-PU07 instruction manual for the handling of the FR-PU04/FR-PU07.) GX Developer and the FR-PU04/FR-PU07 cannot be connected and used simultaneously.

4)Check the PLC series and sequence program capacity in the GX Developer parameters (refer to page 4).

5) Refer to the GX Developer manual and write the sequence program.

CAUTION

•A sequence program cannot be written with its steps specified. If written,

the sequence program does not run. (The program outside the specified range is initialized.)

•Do not read the built-in PLC function parameters and sequence program

without writing them to the inverter once using GX Developer. Since the inverter does not have normal data, always write the built-in PLC function parameters and sequence program once.

•Since the built-in PLC function parameters and sequence program are

written to the flash ROM, there are restrictions on the number of write times. (Approximately 100,000 times)

REMARKS

When Pr. 79 is other than 0, the mode is fixed.

There are no restrictions on operation mode switching. On normal completion of operation mode setting, the write completion signal (X23) turns on, and at the same time, 0 is set to D9150. If the value written is other than H0000 to H0002 or write is performed during inverter operation, HFFFF is set to D9150 as soon as the write completion signal (X23) turns on, resulting in abnormal completion. If abnormal completion occurs, the operation mode is not changed.

The following program changes the operation mode to the NET mode.

(2) Set frequency (RAM) (D9144)

The D9144 data is written to the RAM as a set frequency. The unit is 0.01Hz. (For example, 6000 indicates 60.00Hz.) When the speed is set, the speed is either 1r/min or 0.1r/min. The range where the frequency can be set is 0 to 12000 (0 to 120.00Hz). When the frequency setting is written normally, the write completion signal (X24) turns on, and at the same time, 0 is set to D9150. If any value outside the range is written, HFFFF is set to D9150 as soon as the write completion signal (X24) turns on, resulting in abnormal completion. If abnormal completion occurs, the set frequency is not changed.

POINT

• The frequency can be set in the PU operation mode and NET operation mode. Refer to the inverter instruction manual (applied).

The following program changes the set frequency (RAM) to 30Hz.

(3) Set frequency (EEPROM) (D9145)

The D9145 data is written to the EEPROM as a set frequency. The unit is 0.01Hz. (For example, 6000 indicates 60.00Hz.) When the speed is set, the speed is either 1r/min or 0.1r/min. The range where the frequency can be set is 0 to 12000 (0 to 120.00Hz). When the frequency setting is written normally, the write completion signal (X25) turns on, and at the same time, 0 is set to D9150. If any value outside the range is written, HFFFF is set to D9150 as soon as the write completion signal (X25) turns on, resulting in abnormal completion. If abnormal completion occurs, the set frequency is not changed.

POINT

• Setting is enabled in the PU operation mode and NET operation mode. (Refer to the Inverter instruction manual (applied).)

Inverter Status Monitoring, Special Registers

(4) Alarm definition batch clear (D9146)

Writing H9696 to D9146 batch-clears the alarm definitions. At completion of clear, the write completion signal (X26) turns on, and at the same time, 0 is set to D9150. If any value outside the setting range is written or write is performed during inverter operation, HFFFF is set to D9150 as soon as the write completion signal (X26) turns on, resulting in abnormal completion. If abnormal completion occurs, the alarm definitions are not cleared.

The following program batch-clears the alarm history.

(1) Inverter operation status control (D9148)

Device for inverter operation status control. The operation of the inverter can be controlled by turning on/off (1, 0) bits b0 to b11 of D9148. All bits are factory-set to "0".

Example: When 5 is set to D9148, bits b0 and b2 are 1 (ON), and STF and RH

therefore turn on to give a high-speed forward rotation command.

Always Note that this function is enabled in the external/NET operation mode. (Not enabled in the PU operation mode.)

Device No. Name

D9150 Inverter parameter access error Always

If any value outside the setting range is written during parameter write, set frequency write, parameter clear, etc. from the sequence program of the inverter, or if write is performed when write is disabled, a write alarm occurs and the corresponding alarm code is stored into D9150.

The parameter No. + H8000 is stored into D9150. Example: If an error occurs during write of Pr.0 Torque boost, H8000 (H0 + H8000) is

stored into D9150. If an error occurs during write of Pr.10 DC injection brake operation frequency, H800A is stored into D9150.

HFFFF is stored into D9150. (Normal 0)

Parameter writing is performed when the parameter number is stored to D9241 (D9243) and parameter writing value to D9242 (D9244), and turns ON the Y29 (Y2B). When writing is completed, X29 (X2B) turns ON to notify the completion. (The device number within parentheses is used to write the parameter setting value to EEPROM.)

1: Parameter-set analog value 2: Analog value input from terminal

As soon as the inverter parameter write completion (X29 (RAM) or X2B (EEPROM)) turns on, 0 is set to D9150 on normal completion. If an error occurs during access to the parameters, e.g. if any value outside the setting range is written or write is performed during inverter operation, the value of parameter No. + H8000 is set to D9150 as soon as the write completion signal (X29 (RAM) or X2B (EEPROM)) turns on, resulting in abnormal completion. If abnormal completion occurs, the parameters are not written. (For example, if an error occurs in the torque boost, H8000 is written to D9150.)

1.9.1 User parameter read/write method

User parameter (Pr.506 to Pr.515) and device (D110 to D119) data can be read/written freely. Data transfer between Pr.506 to Pr.515 and D110 to D119 is executed automatically.

1)User parameter write processing When values are written to Pr.506 to Pr.515 using the FR-PU04 or computer link communication, they are written to the parameter storing RAM area and EEPROM area, and further to D110 to D119 simultaneously.

2)User parameter read processing When values are written to D110 to D119 from the PLC function side, they are written to the parameter storing RAM area (Pr.506 to Pr.515) and read using the FR- PU04/FR-PU07 or communication(RS-485 or communication option). (Since data are not written to the EEPROM, making power-on reset returns the data to the original values.)

3)Processing performed at inverter reset or power restoration When the inverter is reset, the Pr.506 to Pr.515 values stored in the EEPROM are transferred to the RAM area and D110 to D119.

Setting Description

Inverter operation lock mode setting

The inverter start signal is made valid regardless of the sequence program execution key.

The inverter start signal is made valid only when the sequence program execution key is set to RUN (SQ signal is turned on). When the sequence program execution key is in the STOP position (SQ signal is off), the inverter does not start if the inverter start signal STF or STR is turned on. (If the key is switched from RUN to STOP during inverter operation, the inverter is decelerated to a stop.)

Overview

3.1 Overview

3.1.1 Outline of Operation Processings

This section outlines processings performed from when the inverter is powered on until a sequence program is executed. The built-in PLC function processings are roughly classified into the following three types. (1) Initial processing

Pre-processing for executing sequence operation. This processing is executed only once when power is switched on or a reset is performed. (a) The inputs/outputs are reset and initialized. (b) The data memories are initialized (the bit devices are turned off and the word

devices are cleared to 0).

setting, operation circuit, etc.

REMARKS

The built-in PLC function parameters can be confirmed from GX Developer. (Refer to the GX Developer Operating Manual.)

(2) Sequence program operation processing

The sequence program written to the built-in PLC function is executed from step 0 to an END instruction.

(3) END processing

Post-processing for terminating one sequence program operation processing and return the sequence program execution to step 0. (a) Self-diagnostic checks are performed. (b) The present values of the timers are updated and their contacts are turned

on/off, and the present values of the counters are updated and their contacts are turned on.

SEQUENCE PROGRAMMING

RUN and STOP Operation Processings

3.2 RUN and STOP Operation Processings

The built-in PLC function has two different operation statuses: RUN status and STOP status. This section explains the operation processings of the built-in PLC function in each operating status. (1) Operation processing in RUN status

A RUN status indicates that a sequence program repeats its operation in order of step 0 to END (FEND) instruction to step 0 when SQ-SD are shorted. (P.RUN is on) When entering the RUN status, the function outputs the output status saved at STOP according to the "STOP to (RUN-time output mode setting" (refer to page 96).

(2) Operation processing in STOP status

A STOP status indicates that a sequence program stops its operation when SQSD are opened or remote STOP is commanded. (P.RUN is off) When entering the STOP status, the function saves the output status and turns off all outputs. The contents of the data memories other than the outputs (Y) are maintained.

POINT

In either the RUN or STOP status, the built-in PLC function is performing I/O refresh processings. In the STOP status, therefore, I/O monitoring and test operation can be performed from the peripheral device.

3.3 Program Makeup

(1) Program classification

The program that can be used by the built-in PLC function is a main sequence program only. Microcomputer, interrupt and SFC programs cannot be used.

(2) Program capacity

A program capacity indicates the capacity of the program storage memory, and it is 1k steps. Set the program capacity in the built-in PLC function parameter.

Programming Languages

3.4 Programming Languages

The built-in PLC function has two different programming methods: one that uses ladders and the other that uses dedicated instructions.

• Programming that uses ladders is performed in the relay symbolic language. *1

• Programming that uses dedicated instructions is performed in the logic symbolic

language. *2 Whether the relay symbolic language or logic symbolic language is used, the same program is created.

REMARKS

*1. When using GX Developer for programming, perform programming in the "ladder mode". *2. When using GX Developer for programming, perform programming in the "list mode".

3.4.1 Relay symbolic language (Ladder mode)

The relay symbolic language is based on the concept of a relay control circuit. You can perform programming in the representation close to the sequence circuit of relay control. (1) Ladder block

A ladder block is the minimum unit for performing sequence program operation. It starts with the left hand side vertical bus and ends with the right hand side vertical bus.

3.4.2 Logic symbolic language (List mode)

The logic symbolic language uses dedicated instructions for programming contacts, coils, etc. instead of their symbols used by the relay symbolic language. (1) Program operation method

Sequence program operation is executed from an instruction at step 0 to an END instruction in due order. When the END instruction is executed, operation is executed from the instruction at step 0 again.

Operation Processing Method of PLC Function

3.5 Operation Processing Method of PLC Function

The operation processing method is the repeated operation of a stored program. (1) Stored program system

1) In a stored program system, a sequence program to be operated is stored in the internal memory beforehand.

2) When sequence program operation is executed, the sequence program stored

in the built-in PLC function is read to the CPU instruction by instruction to execute the operation, and the corresponding devices are controlled according to the results.

(2) Repeated operation system

In a repeated operation system, a sequence of operations is repeated. The built-in PLC function repeats the following processings.

1) The built-in PLC function executes the sequence program stored in the

internal memory from step 0 in due order.

2) When the END instruction is executed, internal processings, such as timer/

counter present value updating and self-diagnostic checks, are performed, and the execution returns to step 0 of the sequence program again.

Step 0 Step 1 Step 2

Built-in sequence function repeats this operation.

END

Timer/counter present value updating Self-diagnostic checks, etc.

Fig 3.5 Operation Processing Method of Built-in PLC Function

REMARKS

A processing from step 0 to next step 0 or from END to next END is called one scan. Therefore, one scan is the sum of the processing time of a user-created program (step 0 to END) and the internal processing time of the built-in PLC function.

I/O Processing Method

3.6 I/O Processing Method

The control system is a refresh system.

3.6.1 What is refresh system?

In the refresh system, control input terminal changes are batch-imported into the input data memory of the CPU before execution of each scan, and the data of this input data memory are used as the input data for operation execution. Each program operation result of the output (Y) is output to the output data memory, and after the END instruction is executed, the contents of the output data memory are batch-output from the control output terminal.

Before execution of step 0, input data are batch-read from the input module (1)) and stored into the input (X) data memory.

• Output refresh

Before execution of step 0, the data of the output (Y) data memory (2)) are batchoutput to the output module.

• When input contact instruction is executed

Input data are read from the input (X) data memory (3)) and the sequence program is executed.

• When output contact instruction is executed

Output data are read from the output (Y) data memory (4)) and the sequence program is executed.

• When output OUT instruction is executed

The operation result (5) of the sequence program is stored into the output (Y) data memory.

3.6.2 Response delay in refresh system

This section describes a delay of an output change in response to an input change. An output change in response to an input change has a delay of up to two scans as shown in Fig. 2.6.

In this ladder, output Y1E turns on when input X5 turns on.

The Y1E output turns on earliest when the control input terminal turns from OFF to ON immediately before a refresh. X5 turns on at an input refresh, Y1E turns on at step 0, and the control output terminal turns on at an output refresh after execution of the END instruction. In this case, therefore, a delay of a control output terminal change in response to a control input terminal change is one scan.

END

The Y1E output turns on latest when the control input terminal turns from OFF to ON immediately after a refresh. X5 turns on at the next input refresh, Y1E turns on at step 0, and the control output terminal turns on at an output refresh after execution of the END instruction. In this case, therefore, a delay of a control output terminal change in response to a control input terminal change is two scans.

Fig 3.7 Output Y Change in Response to Input X Change

3.7 Scan Time

(1) Scan time

A scan time is a time from when sequence program operation is executed from step 0 until step 0 is executed again. The scan time of each scan is not equal, and changes depending on whether the used instructions are executed or not.

(2) Scan time confirmation

(a)The scan time from the END instruction to the next END instruction is timed in

the PLC, and stored into the special registers D9017 to D9019 in units of 10ms.

1) Data stored into special registers D9017 to D9019

2) Scan time accuracy The accuracy of the scan time observed in the PLC is 10ms.

For example, when the D9018 data is 5, the actual scan time is 40ms to 60ms.

Numerical Values Usable in Sequence Program

3.8 Numerical Values Usable in Sequence Program

The built-in PLC function represents numerical values, alphabets and other data in two statuses: 0 (OFF) and 1 (ON). The data represented by these 0s and 1s are called BIN (binary code). The built-in PLC function can also use HEX (hexadecimal code) that represents BIN data in blocks of four bits. Table 2.1 indicates the numerical representations of BIN, HEX and decimal code.

Numerical Values Usable in Sequence Program

3.8.1 BIN (Binary Code)

(1) Binary code

BIN is a numerical value represented by 0s (OFF) and 1s (ON). In the decimal code, a number is incremented from 0 to 9, and at this point, a carry occurs and the number is incremented to 10. In BIN, 0, 1 are followed by a carry, and the number is incremented to 10 (2 in decimal). Table 2.2 indicates the numerical representations of BIN and decimal code.

(2) Numerical representation of BIN

1) Each register (e.g. data register) of the built-in PLC function consist of 16 bits. Each bit of the register is assigned a 2

However, the most significant bit is used to judge whether the value is positive or negative.

• Most significant bit is 0 ..... Positive

• Most significant bit is 1 ..... Negative

The numerical representation of each register of the built-in PLC function is shown in Fig. 2.8.

2) Numerical data usable with the built-in PLC function In the numerical representation shown in Fig. 2.8, values can be represented in

the range -32768 to 32767. Therefore, each register of the built-in PLC function can store any value between -32768 and 32767.

3.8.2 HEX (HEX Decimal)

(1) HEX

HEX represents four bits of BIN data as one digit. Using four bits in BIN, you can represent 16 values from 0 to 15. Since HEX represents any of 0 to 15 in a single digit, 9 is followed by alphabets A (instead of 10), B (11)..., and F (15) is followed by a carry. Refer to page 72 for the correspondences between BIN, HEX and decimal code.

(2) Numerical representation of HEX

Each register (e.g. data register) of the built-in PLC function consist of 16 bits. Therefore, the value that can be stored into each register is represented as any of 0 to HFFFF in HEX.

Description of devices

3.9.2 Inputs, Outputs X, Y

Inputs and outputs are devices designed to transfer data between the inverter and external devices. Inputs provide ON/OFF data given to the corresponding control input terminals from outside the inverter. In a program, they are used as contacts (normally open, normally closed contacts) and the source data of basic instructions. Outputs are used when the operation results of a program are output from the control output terminals to outside the inverter.

3.9.3 Internal Relays M

Internal relays are auxiliary relays that are used in the PLC function and cannot latch data (backup for power failure). All internal relays are turned off when:

• Power is switched from off to on; or

• Reset is performed.

There are no restrictions on the number of contacts (N/O and N/C contacts) used in the program. Use outputs (Y) when outputting the operation results of the sequence program to outside the inverter.

No restrictions on the number of used contacts.

3.9.4 Timers T

The timers of the PLC function are count up timers. The count up timer starts timing the present value when its coil turns on, and the contact of that timer turns on when the present value reaches the setting (time-out).

3.9.5 100ms, 10ms and 100ms retentive timers

(1) 100ms and 10ms timers

The timer starts timing the present value when its coil turns on, and the present value is reset to 0 and the contact turns off when the coil turns off.

When input X5 turns on, T2 coil turns on and timer times 5s. (T2 is 100ms timer.)

Setting

Description of devices

(2) 100ms retentive timers

1) A 100ms retentive timer is designed to time the ON period of the timer coil. When its coil turns on, the timer starts timing the present value and maintains the present value and contact ON/OFF state if the coil turns off. When the coil turns on again, the timer resumes timing from the maintained present value.

2) Use the RST T instruction to clear the present value and turn off the contact.

3.9.6 Timer processing method and accuracy

(1) Timer processing method

The coil of the timer is turned on/off at execution of the OUT T instruction, and the timer's present value is updated and its contact turned on/off at execution of the END instruction.

1) When the coil of the timer turns on, the present value of that timer is updated after execution of the END instruction, and when the timer times out, its contact turns on. (a) When the coil of the 10ms or 100ms timer turns off, the present value of

that timer is reset to 0 and the contact is also turned off after execution of the END instruction.

(b) If its coil turns off, the 100ms retentive timer maintains the prevent value

and contact ON/OFF state.

2) When the timer is reset by the RST instruction, the present value of the timer is reset to 0 and the contact turns off too at execution of the RST T instruction.

POINT

If the timer setting is "0", the setting becomes infinite and the timer does not time out.

Description of devices

(2) Present value update timing and accuracy in refresh system

1) The timer accuracy is +2 scan times independently of the used timer and scan time.

2) The following shows the present value update timing and accuracy when the 10ms timer is used in a program where the scan time is 10ms or more.

*2 .......... Error produced by timer's input condition ON timing and OUT

T instruction's program position (+1 scan time)

The accuracy is +2 scan time (+0.05s in Fig. 3.8)

3) When the timer times out, its contact remains on until END even if the coil turns off, and turns off at execution of the END instruction.

Counters C

3.10 Counters C

The counters of the built-in PLC function are up counters. An up counter stops counting and its contact turns on when the count value reaches the setting. (1) Count processing

1) The coil of the counter is turned on/off at execution of the OUT C instruction, and its present value is updated and its contact turns on after execution of the END instruction.

2) The counter counts on detection of the leading edge (OFF to ON) of the coil. It does not count if the coil remains on.

(2) Counter resetting

1) The count value is not cleared even if the coil turns off. Use the RST C instruction to clear the count value and turn off the contact.

2) When the counter is reset by the RST instruction, the present value and contact of the counter are cleared at execution of the RST instruction.

How to RUN/STOP the Built-in PLC Function from Outside (Remote RUN/STOP)

3.14 How to RUN/STOP the Built-in PLC Function from Outside (Remote RUN/STOP)

The built-in PLC function is RUN/STOPped by shorting/opening SQ-SD. Remote RUN/STOP is to RUN/STOP the built-in PLC function from outside the inverter with SQ-SD shorted (RUN status). (1) Applications of remote RUN/STOP

In the following cases, the function can be RUN/STOPped by remote operation using remote RUN/STOP.

1) When the inverter is out of reach.

2) When the inverter in a control box is RUN/STOPped from outside the control box.

(2) Operation performed at remote RUN/STOP

The operation of the sequence program for performing remote RUN/STOP is as described below.

• Remote STOP.......The function enters the STOP status after the sequence

program is executed up to the END instruction.

• Remote RUN ........When remote RUN is performed after the function has been

put in the "STOP status" by remote STOP, the function enters the RUN status again and executes the sequence program from step 0.

(3) Remote RUN/STOP method

There are the following remote RUN/STOP methods.

1) Setting using built-in PLC function parameter (using contact) Remote RUN/STOP can be performed by turning the remote RUN contact off/on. For example, this method can be used to STOP the PLC function with the emergency stop contact.

• When the remote RUN contact turns off, the function enters the "RUN" status.

• When the remote RUN contact turns on, the function enters the "STOP"

status.

(4) Instructions

Note the following points since the built-in PLC function gives priority to STOP.

• The built-in PLC function enters the STOP status when remote STOP is

performed from any of the remote RUN contact, GX Developer, etc.

• To place the built-in PLC function in the RUN status again after it has been put

in the STOP status by remote STOP, all external factors (remote RUN contact, GX Developer, etc.) for remote STOP must be set to RUN.

REMARKS

What are RUN and STOP statuses?

•RUN status.............Status where a sequence program is repeating operation from step 0 to

END instruction.

•STOP status ..........Status where sequence program operation is at a stop and the outputs

(Y) are all off.

Watchdog Timer (Operation clog up monitor timer)

3.15 Watchdog Timer (Operation clog up monitor timer)

(1) Watchdog timer

A watchdog timer is the internal timer of the built-in PLC function designed to detect hardware or sequence program faults. Its default value is set to 200ms.

(2) Watchdog timer resetting

The built-in PLC function resets the watchdog timer before execution of step 0 (after execution of END processing). When the built-in PLC function operates properly and the END instruction is executed within the setting in the sequence program, the watchdog timer does not time out. If the hardware fault of the built-in PLC function occurs or the scan time of the sequence program is too long to execute the END instruction within the setting, the watchdog timer times out.

Internal

processing time

END 00

WDT resetting

(Internal processing)

Excess of scan time over setting results in watchdog timer error.

Fig 3.23 Watchdog Timer Resetting

(3) Processing performed when watchdog timer times out

If the scan time exceeds the watchdog timer setting, a watchdog timer error occurs and:

1) The built-in PLC function turns off all outputs.

2) The P.RUN LED goes off or flickers.

3) M9008 turns on and the error code is stored into D9008.

REMARKS

The watchdog timer setting can be changed by built-in PLC function parameter setting of GX Developer. (Refer to the GX Developer manual for details.)

Self-diagnostic Function

3.16 Self-diagnostic Function

The self-diagnostic function diagnoses faults by the built-in PLC function itself. (1) Self-diagnostic timing

The self-diagnostic function is performed at power-on, at reset, at execution of any instruction, or at execution of the END instruction.

1) At power-on, at reset

Whether operation can be executed or not is diagnosed.

2) At execution of any instruction

An error occurs if the operation of any instruction in the sequence program is not executed properly.

CAUTION

For the LD, AND, OR, logical comparison operation, and OUT instructions, the set devices are always checked. For the other instructions (SET, RST, MOV, etc.), a check is made as soon as the execution condition holds and the instruction is ready to be executed.

3) At execution of END instruction

Operation clog up monitor timer

(2) Operation mode at fault detection

There are two different PLC operation modes at detection of a fault by the selfdiagnostic: operation stop mode and operation continuation mode. The operation continuation mode includes a fault that enables operation to be stopped by built-in PLC function parameter setting.

1) If an operation stop error is detected by the self-diagnostic, operation is

stopped and outputs (Y) are all turned off as soon as the error is detected. The other devices maintain their states at occurrence of the error.

(Refer to page 94)

2) If an operation continuation error is detected, only the faulty program part is not

executed and the program at the next step is executed.

(3) Error definition checking

When M9008 (self-diagnostic error) turns on at detection of an error, the error code is stored into D9008 (self-diagnostic error). Especially in the continuation mode, use it in the program to prevent a mechanical system malfunction. For the errors detected by the self-diagnostic, refer to the error code list on

Keyword Registration

3.17 Keyword Registration

The keyword is designed to inhibit the read and rewrite of the program and comments in the built-in PLC function using GX Developer. (1) Read/write from built-in PLC function where keyword has been registered

When the keyword has been registered, the built-in PLC function parameters, main program and comments cannot be read/written from the built-in PLC function to the GX Developer device unless the keyword registered to the built-in PLC function is entered.

(2) Registration and cancel of keyword

A keyword of up to six digits can be set in hexadecimal (0 to 9, A to F). Make built-in PLC function parameter setting to register or cancel the keyword.
