SAFETY PRECAUTIONS

WARNING

CAUTION

Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in minor or moderate injury or property damage.

(Read these precautions before using this product.)

Before using the product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly.

In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".

Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to

serious consequences. Observe the precautions of both levels because they are important for personal and system safety. Make sure that the end users read this manual and then keep the manual in a safe place for future reference.

[DESIGN PRECAUTIONS]

WARNING

Configure safety circuits external to the programmable controller to ensure that the entire system operates safely even when a fault occurs in the external power supply or the programmable controller. Failure to do so may result in an accident due to an incorrect output or malfunction.

(1) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and

protective interlock circuit for forward/reverse operation or upper/lower limit positioning.

(2) When the programmable controller detects the following error conditions, it stops the operation

and turn off all the outputs.

• Overcurrent or overvoltage protection of the power supply module is activated.

• The CPU module detects an error such as a watchdog timer error by the self-diagnostic function. All outputs may turn on when an error occurs in the part, such as I/O control part, where the CPU module cannot detect any error. To ensure safety operation in such a case, provide a safety mechanism or a fail-safe circuit external to the programmable controller. For a fail-safe circuit example, refer to Chapter 9 LOADING AND INSTALLATION in this manual.

(3) Outputs may remain on or off due to a failure of an output module relay or transistor. Configure

an external circuit for monitoring output signals that could cause a serious accident.

In an output module, when a load current exceeding the rated current or an overcurrent caused by a load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an external safety circuit, such as a fuse.

A - 1

[DESIGN PRECAUTIONS]

WARNING

Configure a circuit so that the programmable controller is turned on first and then the external power supply. If the external power supply is turned on first, an accident may occur due to an incorrect output or malfunction.

For the operating status of each station after a communication failure, refer to relevant manuals for the network. Incorrect output or malfunction due to a communication failure may result in an accident.

When controlling a running programmable controller from a peripheral connected to the CPU module or from a personal computer connected to a special function module, configure an interlock circuit in the sequence program to ensure that the entire system will always operate safely. For program modification and operating status change, read relevant manuals carefully and ensure the safety before operation. Especially, in the case of a control from an external device to a remote programmable controller, immediate action cannot be taken for a problem on the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the sequence program , and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

When setting up the system, do not allow any empty slot on the base unit. If any slot is left empty, be sure to use a blank cover (A1SG60) or a dummy module (A1SG62) for it. Otherwise, internal parts of the module may be flied in the short circuit test or when an overcurrent or overvoltage is accidentally applied to the external I/O section.

CAUTION

Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise.

When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a large current (approximately ten times greater than normal) may flow when the output is turned from off to on. Take measures such as replacing the module with one having a sufficient current rating.

After the CPU module is powered on or is reset, the time taken to enter the RUN status varies depending on the system configuration, parameter settings, and/or program size. Design circuits so that the entire system will always operate safely, regardless of the time.

[INSTALLATION PRECAUTIONS]

CAUTION

Use the programmable controller under the environment that meets the general specifications in this manual. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

To mount the CPU module, while pressing the module mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place. Incorrect mounting may cause malfunction, failure or a drop of the module. When using the programmable controller in an environment of frequent vibrations, fix the module with the screw. Tighten the screw within the specified torque range. Undertightening can cause drop of the screw, short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

Insert securely the module fixing projection at the bottom of the AnS series module into the fixing hole in the base unit and then tighten the module fixing screw within the specified torque. When no screw is tightened, even if the module is installed correctly, it may cause malfunctions, a failure or a drop of the module. Tightening the screw excessively may damage the screw and/or the module, resulting in a drop of the module, a short circuit or malfunctions.

When using an extension cable, connect it to the extension cable connector of the base unit securely. Check the connection for looseness. Poor contact may cause incorrect input or output.

When using a memory card, fully insert it into the memory card slot. Check for incomplete connection after installing it. Poor electrical contact may cause malfunctions.

Shut off the external power supply for the system in all phases before mounting or removing the module. Failure to do so may result in damage to the product.

Do not directly touch any conductive part of the module. Doing so can cause malfunction or a failure of the module.

USER PRECAUTIONS

Precautions for using a CPU module

When a CPU module is used for the first time, data in the CPU module (built-in RAM, device data) and in the memory card are undefined. Before writing data (parameters, programs) to the CPU module, clear data in the built-in RAM using a peripheral (PC memory clear operation) and also clear data using the RESET/L.CLR switch of the CPU module (latch clear operation).

Precautions for battery

(1) Operating a CPU module after being stored without a battery

When a CPU module is operated again after being stored without a battery, data in the CPU module (built-in RAM, device data) and a memory card may be undefined. Before operating the CPU module again, clear data in the built-in RAM using a peripheral (PC memory clear operation) and also clear data using the RESET/L.CLR switch of the CPU module (latch clear operation).* After all data are cleared, write the backed-up data in the CPU module or the memory card.

(2) Operating a CPU module after being stored over the battery life

When a CPU module is operated again after being stored over the battery life, data in the CPU module (built-in RAM, device data) and a memory card may be undefined. Before operating the CPU module again, clear data in the built-in RAM using a peripheral (PC memory clear operation) and also clear data using the RESET/L.CLR switch of the CPU module (latch clear operation).* After all data are cleared, write the backed-up data in the CPU module or the memory card.

POINT

Make sure to back up each memory contents before storing the programmable controller.

* For details of the PC memory clear operation using a peripheral, refer to the following manuals.

GX Developer Operating Manual

A6GPP/A6PHP Operating Manual

SW IVD-GPPA Operating Manual

For the latch clear operation using the RESET/L.CLR switch of the CPU module, refer to Section

4.6.3.

1. OVERVIEW

1 OVERVIEW

This user's manual describes the performance, functions, and handling method of the QCPU-A, as well as the specifications and handling of the memory card, power supply module and the base unit.

The programming modules and software packages have to be compatible with the upgraded A2UCPU, A2UCPU-S1, A3UCPU, and A4UCPU (abbreviated as AnUCPU hereafter). When the conventional programming modules and software packages are used, the usable range varies depending on the model of the CPU (programmable controller model name).(Refer to Section 2.2.3.)

Related to each module used in the CPU modules, check "System equipment list" in Section 2.3. Refer to Section 2.2.1 for the special function modules which have limited usable devices range.

2. SYSTEM CONFIGURATION

2.2.2 Software package

(1) GPP function software packages and model name setting at the start-up

The following table shows the GPP function software package that can be used to create the QCPU-A program, and the programmable controller type setting at startup. When using SW4D5C-GPPW or later, select the programmable controller type from Q02(H)-A or Q06H-A according to the CPU to be used. When using the peripheral devices and GPP function software package of SW3D5CGPPW or earlier, specify the programmable controller type name as "A4U". If "A4U" is not found in PLC type names, specify "A3A." If both "A4U" and "A3A" are not found, specify "A3H." Note that when "A4U" is specified, the available device range is limited.

SYSTEM CONFIGURATION2.

POINT

(1) Old software packages other than listed above cannot be used. (2) To construct MELSECNET/10 network system with QCPU-A, use the AnU-

compatible GPP function software package (which includes "A4U" in its programmable controller type name). A network cannot be constructed with the GPP function software package which is not compatible with AnU (which does not include "A4U" in its programmable controller type name).

(3) Communication with GX Developer at 115.2kbps may not be available

depending on the peripheral devices. In such a case, select the lower communication speed.

(4) When using Q02(H)CPU-A and conventional peripheral devices and setting

the programmable controller type as "A4U," designate the main program setting to 28k steps or less with parameters. When "Main + parameter" is written with the programmable controller with the setting of 29k steps or more, "Cannot communicate with PC" is displayed, and writing to the CPU module is disabled.

(5) Subprograms cannot be used with Q02(H)CPU-A. When using conventional

peripheral devices and setting the programmable controller type as "A4U," do not specify any subprograms. If any subprograms are specified, "Cannot communicate with PC" is displayed. With Q06HCPU, subprogram 1 can be used, but subprograms 2 and 3 cannot. When subprogram 2 or 3 is specified, the same message above is displayed.

Up to 7 extension base units can be added.

Limit the total length of the extension cable to 13.2m or less.

When using extension cables, keep them away from the main circuit cables (high voltage,

large current).

Assign the extension stage numbers in ascending order. Do not assign two or more modules

to one stage.

Connect the extension cable from OUT of the extension cable connector of the base unit to in

of the connector of the next extension base unit.

The QA1S51B can be connected to the last extension stage only because it does not have

an extension cable connector (OUT).

4.1.1 Overview of operation processing

An overview of processing when starting power supply for the CPU module to execution of the sequence program is explained. CPU modules processing may be categorized roughly into the following four kinds:

(1) Initial processing

This is a preprocess to execute sequence operations, and is performed only once upon power-on or reset. (a) Resets the I/O module and initialize it.

(b) Initializes the range of data memory for which latch is not set up (turns off the bit

device and sets the word device to 0).

number or the position of installation on the extension base unit.

(d) Execute the self-diagnostics check for the parameter setting and the operation

circuit. (Refer to Section 4.1.4)

(e) For the control station of the MELSECNET/10 or the master station of

MELSECNET (II)/B, sets the network/link parameter information to the network/ data-link module, and commences the network communication/data link.

(2) Refresh processing of I/O module

Executes the refresh processing of I/O module. (Refer to the ACPU/QCPU-A (A Mode) Programming Manual (Fundamentals).)

(3) Operation processing of a sequence program

Executes the sequence program from step 0 to the END instruction written in the programmable controller CPU.

(4) END processing

This is a post-process to finish one cycle of operation processing of the sequence program and to return the execution of the sequence program to the step 0. (a) Executes self-diagnosis checks, such as a fuse blown, a module verify, and a

low battery. (Refer to Section 4.1.4)

(b) Updates the current value of the timer, sets the contact on/off, updates the

current value of the counter and sets the contact to on. (Refer to the ACPU/QCPU-A (A Mode) Programming Manual (Fundamentals).)

(d) Executes the refresh processing when there is a refresh request from the

network module or link module.

(e) When the trace point setting of sampling trace is by each scan (after the

execution of END instruction), stores the device status for which it is setup into the sampling trace area.

(f) By setting link information, I/O storage device, etc. of the MELSECNET/MINI-S3

to the parameters, auto refresh processing of the A1SJ71PT32-S3 master module is performed. (Refer to Section 4.2.6)

POINT

When executing the FROM/TO instruction for the special function module frequently in short scan time, it may cause the target special function module operation error. When executing FROM/TO instruction to the special function module, set the processing time and converter time by using such as a timer and a constant scan function of the special function module.

4.1.2 Operation processing of RUN, STOP, PAUSE, and STEP-RUN

The programmable controller CPU has four kinds of operation status: RUN status, STOP status, PAUSE status, and step operation (STEP-RUN) status. Operation processing of programmable controller CPU in each operation status is explained.

(1) RUN status operation processing

(a) The repetition of sequence program operation in the order from step 0 END

(FEND) instruction step 0 is called the RUN status.

(b) When entering the RUN status, the output status saved by STOP is output

depending on the output mode setting of parameter upon STOP RUN.

program operation is usually one to three seconds, although it may vary depending on the system configuration.

(2) STOP status operation processing

(a) The termination of operation of the sequence program by the use of the RUN/

STOP key switch, the remote STOP, or at the execution of STOP instruction is called the STOP status. (Refer to Section 4.3)

(b) When entering the STOP status, it saves the output status and sets all output

points to OFF. Data memories except for output (Y) are retained.

(3) PAUSE status operation processing

(a) The termination of operation of sequence program while retaining output and

data memories is called the PAUSE status. (Refer to Section 4.3)

(4) Step operation (STEP-RUN) operation processing

(a) Step operation is an operation mode wherein operation processing of a

sequence program can be paused/resumed by each instruction from peripheral device(s). (Refer to Section 4.3)

(b) Since an operation processing is paused while retaining the output and data

memories, condition of the execution can be confirmed.

4. CPU MODULE

4.1.3 Operation processing upon instantaneous power failure

The programmable controller CPU detects a momentary power failure when input power voltage supplied to the power supply module becomes lower than the specified range. When the programmable controller CPU detects an instantaneous power failure, the following operation processing is performed.

(1) When an instantaneous power failure shorter than allowable momentary power

failure period occurred: (a) When an instantaneous power failure occurred, the operation processing is

interrupted while the output status is retained.

(b) When the instantaneous power failure is reset, the operation processing will be

continued.

interrupted, measurement of the watchdog timer (WDT) continues. For instance, in the case that WDT is 200ms and the scan time is 190ms, if an instantaneous power failure of 15ms occurs, it causes the watchdog timer error.

Instantaneous power failure occurred

END 0

Operation processing upon instantaneous power failure

Power supply restoration

(2) When an instantaneous power failure longer than the allowable momentary power

failure period occurred: The programmable controller CPU performs the initial start. The operation processing is the same as power-on or reset operation with the reset switch.

4. CPU MODULE

4.1.4 Self-diagnostics functions

Self-diagnosis is a function that a CPU module diagnoses itself for the presence of any abnormalities.

(1) While turning on the programmable controller power or when an error occurs in the

programmable controller RUN, the error is detected and displayed, and the operation is stopped by the self-diagnostics function, which the CPU module performs, to prevent programmable controller malfunctions and give preventive maintenance.

(2) The CPU module stores the error occurred last to a special register D9008 as an

error code, and stores further detailed error code to a special register D9091.

(3) Even with the power-off, the latest error information and 15 errors in the past are

stored by battery backup. With a GPP function software package for the AnUCPU, contents of up to 16 errors can be confirmed with the peripheral devices. Reset (All clear) in the past error information can be performed by operating "latch clear" in the CPU module. The following shows contents of the error information. (The error which occurred last):

(a) The time and date of error occurrences..... Year, month, day, hour, minute,

(4) When detecting an error by self-diagnosis, QCPU takes action in the following

modes:

• Mode wherein the programmable controller operation is stopped

• Mode wherein the programmable controller operation is continued In addition, some errors can be skipped or stopped by setting parameters. (a) When an operation stop error is detected by the self-diagnosis, the AnSHCPU

stops the operation at error detection, and sets the all outputs(Y) to OFF.

(b) When an error of operation continued is detected, the only part of the program

with the error is not executed while the other part is executed. Also, in the case of module verify error, the operation is continued using the I/O

address prior to the error. Since error occurrence and error contents are stored in the special relay (M) and special register (D) at error detection, use in the program for preventing any malfunctions of the programmable controller or mechanical system especially in mode wherein the programmable controller operation is continued.

Error definition detected by the self-diagnosis are shown in the next page.

(1) As to the LED indication message, the order of priority of the LED

indication can be changed if CPU module is in the operation mode. (Error codes are stored in the special register.)

(2) When the special relay M9084 is on, checking on fuse blown, I/O

verification and the battery are not performed. (Error codes are not stored in the special register.)

The memory area for the sequence program for QCPU-A is the same as that for MELSECNET/10. Therefore, the remainder of subtracting the memory area used by MELSECNET/10 network parameters from the maximum 30k steps can be used for the memory area for the sequence program. Note that the sequence program can use only up to 22k steps when the maximum 16k bytes are used for the MELSECNET/10 network parameters.

4.2.3 Setting ranges of timer and counter

(1) Timer setting range

(a) Default values of the timer setting ranges are as follows:

Timer points :256 points 100ms timer :T0 to T199 10ms timer :T200 to T255 Retentive timer :None

(b) When timer-use points are set to 257 or more, the default values will be as

follows:

100ms timer :T0 to T199 10ms timer :T200 to T255 100ms timer :T256 to T2047

units, and T256 to T2047 in 16 point units. By setting the timer points actually to be used, the timer processing time subsequent to the END instruction can be shortened.

(d) Timer setting values are as follows:

T0 to T255 : constant or word device (D) T256 to T2047 : word device (D, W, R)

(Allocate a storage device for the set value by setting parameters.)

(2) Counter setting range

(a) Default values of counter setting ranges are as follows:

Counter points :256 points Normal counter :C0 to C255 Interrupt counter :None

(b) When the counter-use points are set to 257 points or more, the default values

will become as follows:

Normal counter :C0 to C255 Normal counter :C256 to C1024

to C255 only, and any counters outside the range cannot be set up. The setup is made with parameters in C224 to C255 by one point for the interrupt counter. Any counter in the range C224 to C255 which is not set up as an interrupt counter can be used as a normal counter.

4 - 22

CPU MODULE4.

The interrupt counters in C224 to C255 are allocated to the interrupt pointers I0 to I31 as shown below, and count the occurrences of interrupts by those of I0 to I31.

(d) The counter-use points can be set arbitrarily by 16 points using the serial

numbers. By setting the counter which points to the number actually used, the counter processing time subsequent to the END instruction can be shortened.

(e) The counter set values are as follows:

C0 to C255 :constant or word device (D)

C256 to C1023 :word device (D, W, R)

(Allocate a storage device for the set value by setting parameters.)

POINT

When the timer-use points are set to 257 points or more or the counter-use points are set to 257 points or more, the set value storage devices (D, W, R) specified at the time of timer/counter use point setup are automatically set in the serial numbers. <Example> When the timer-use points are set to 512 points and the set value storage device is set to D1000, D equivalent to 256 points (D1000 to D1255) in T256 to T511 becomes the devices for the set values using the continuous numbers.

4.2.4 I/O devices

QCPU-A has 8192 I/O device points (X/Y0 to X/Y1FFF) each for input (X) and output (Y). There are actual I/O devices and remote I/O devices in this I/O range.

(1) Actual I/O device

(2) Remote I/O device

This is the device range where an I/O module or special function module can be installed to the main base unit/extension base unit and controlled.

Q02CPU-A, Q02HCPU-A, Q06HCPU-A

The remote I/O devices, following the actual I/O devices or later, can be used for the following objectives: (a) Allocate to a remote I/O station in the MELSECNET data link system. (b) Allocate to a remote I/O station in the MELSECNET/10 network system. (c) Allocate to the reception data storage device or transmission data storage

device in the MELSECNET/MINI-S3's auto refresh setting.

4.2.6 MELSECNET/MINI-S3 auto refresh processing

By setting link information, I/O storage device, etc. of the MELSECNET/MINI-S3 to the parameters, the module automatically communicates with the buffer memory area for the batch refresh send/received data of the A1SJ71PT32-S3/AJ71PT32-S3 master module (abbreviated as the master module hereafter).

Sequence programs can be created using the I/O devices allocated to send/received by the auto refresh setting. (The FROM/TO instructions are not required.)

POINT

(1) Since up to 8 master modules can be set for auto refresh by the parameter,

auto refresh is possible for up to 8 modules. When 9 or more modules are desired, use the FROM/TO instruction in the sequence program from the 9th module.

(2) Since auto refresh is not possible with send/received data for the separate

refresh I/O modules and for the remote terminal modules No.1 to No.14, use them by the FROM/TO instructions. However, the remote terminal modules shown below are subject of auto refresh in the limited area:

AJ35PTF-R2 RS-232C interface module AJ35PT-OPB-M1-S3 mount-type tool box AJ35PT-OPB-P1-S3 portable type tool box

(3) For the master modules set up for auto refresh, since the CPU module

automatically turns on the link communication start signal Y(n+18) or Y(n+28), it is not necessary to turn it on from the sequence program.

(4) Auto refresh of I/O data is performed by batch after the CPU module

executes the END instruction. (Auto refresh processing is performed when the CPU module is in the RUN/PAUSE/STEP-RUN status.)

(5) The master module may perform the processing while the link

communication start signal Y(n+28) is off depending on the remote terminal modules connected. For instance, if the AJ35PTF-R2 RS-232C interface module is used without protocol, it is necessary to write parameters to the parameter area (buffer memory address 860 to 929) while the link communication start signal is off. Since the link communication start signal turns on after the CPU module enters the RUN status and one scan is performed, write the parameters during the first 1 scan.

(b) Send data storage device

1) Set the device number (Y400) for b0 of the station 1 as a send data storage device.

2) The send data storage device occupies from Y400 to Y45F. For the present system example, since the total number of stations is odd, it is occupied for one extra station.

3) The device numbers of output modules connected are as follows:

Stations 9 to 10 AX40Y50C Y440 to Y44F

Station 11 AJ35TJ-8R Y450 to Y457 With respect to Y400 to Y43F and Y458 to Y44F, they are simultaneously refreshed, but are not output.

POINT

(1) Set the send and received data storage devices so that device numbers are

not overlapped. When the received data storage device is set to B0 in the system configuration example, it occupies B0 to B5F as the device range. Set the send data storage device to B60 or later. When the send data storage device is set to B60, the device range will be B60 to BBF.

(2) If a bit device is specified as the send/received data storage device, the

device number set must be a multiple of 16.

(3) Device range used is (8 points) (Number of stations).

When the number of stations is an odd number, extra 8 points are necessary.

4.4 Functions added to QCPU-A

This section describes the new functions added to QCPU-A (A mode) which are not available with A2USHCPU-S1.

4.4.1 Boot operation from built-in ROM

Boot operation can be performed by booting parameters and sequence programs from the built-in ROM to the built-in RAM at start-up. The boot operation from the built-in ROM allows the retention of sequence programs without using batteries even when the power is off. The following shows the procedure for the boot operation from the built-in ROM:

(1) Operation methods

There are two methods to operate QCUP-A: The RAM operation uses the built-in RAM. The boot operation uses the built-in ROM and boots parameters and sequence programs from the built-in ROM to the built-in RAM at start-up. QCPU-A allows checking the current operation method by setting DIP switch 3 and M9073. The following table shows the setting combination.

Designate the device in the unit of 16 points.

4.4.2 Usage of 1ms timer

With QCPU-A, a 1ms timer can be used in addition to the conventional high-speed timer (10ms) and low-speed timer (100ms).

(1) Usage

Adding ZHTIME, a 1ms timer setting instruction, in a program enables the use of a 1ms timer. (The ZHTIME instruction must be written in the main program.) The ZHTIME instruction is checked at start-up and at switching from STOP to RUN. When this instruction exists in the main program, the 1ms timer can be used. If the ZHTIME instruction does not exist in the main program, only the 100ms/10ms timer can be used, and the 1ms timer is disabled. The number of occupied points is set as the total points of the 100ms timer, 10ms timer, retentive timer, and 1ms timer. The area for the 1ms timer is reserved following that of the retentive timer. Consequently, the constant specified with the ZHTIME instruction is designated as the device number following that of the retentive timer specified by parameters in the unit of 16 points.

(2) Use example of the ZHTIME instruction

The following shows the use example of the ZHTIME instruction.

Example) When the timer in 1ms is set at T208 or later:

According to the setting above, the devices designated for the 100ms timer are T0 to T239, for the 10ms timer are T240 to T319, for the retentive timer are T320 to T399, and for the 1ms timer are T400 to T511.

POINT

Note the following points to use the ZHTIME instruction. (1) The ZHTIME instruction must be written in the main program. (2) The ZHTIME instruction must be designated in the unit of 16 points. (3) The number of occupied points designated in the timer setting by parameters

should include those for the 1ms timer.

(4) When the range for the timer setting by parameters is between T256 and

2047, the initial device number to be used should be set at the item of the retentive timer between T256 and 2047. The 100ms timer should be used as the retentive timer.

Turns from on to off M9077 and clears the

accumulation time.

When 1 to 255 is designated at D9077, M9077 is

turned on at the first scan.

When a value other than 1 to 255 is designated at

D9077, the value in D9077 is reset to 0 and M9077 is

always turned off.

When a value other than 1 to 255ms is designated,

the value in D9077 is reset to 0.

4.4.3 Sequence accumulation time processing

With QCPU-A, as the scan time becomes faster, it may affect the processing of FROM/TO instruction or the scan time for special function modules. Such problems can be avoided by using the following special relay and special register as interlock and executing FROM/TO instruction in the unit of several ms.

(1) Procedure

In the diagram above, M9077 is ON at the first scan so that the instruction is executed. At the beginning of the second scan, the accumulation time does not reach 5 ms. As a result, M9077 turns OFF, the accumulation time is cleared, and the instruction is not executed. At the end of the second scan, the accumulation time does not reach 5 ms, so that M9077 remains OFF and the instruction is not executed. At the end of the third scan, the accumulation time exceeds 5ms. As a result, M9077 turns ON, the accumulation time is cleared, and the instruction is executed at the forth scan. At the end of the forth scan, the accumulation time exceeds 5ms, so that M9077 remains ON and the instruction is executed at the fifth scan. At the end of the fifth scan, the accumulation time does not reach 5ms so that M9077 turns OFF. The accumulation time is cleared and the instruction is not executed at the sixth scan.

In the diagram above, M9077 is always ON when the scan time is always longer than the setting value (D9077).

The following program example executes the FROM/TO instruction in the unit of several seconds using M9077 and D9077 above.

*1 The setting range for the sequence accumulation time is 1 to 255ms (default: 5ms).

The value in D9077 should be in the range between 1 and 255. Otherwise, the value in D9077 is reset to 0 and M9077 is always OFF.

*2 If the instruction signal for the FROM/TO instruction is a pulse signal, the interlock with M9077

may mask the FROM/TO instruction, disabling execution. In such a case, keep the instruction signal once in the other device.

*3 If execution order is set to the FROM/TO instruction, adding M9077 may change the

execution order. In such a case, do not use M9077, and make the execution interval of the FROM/TO instruction longer with a user program.

4.5 Handling Precautions

The following shows precautions when handling the CPU module from unpacking to installation.

CAUTION

When using an extension cable, connect it to the extension cable connector of the base unit securely. Check the connection for looseness. Poor contact may cause incorrect input or output.

When using a memory card, fully insert it into the memory card slot. Check that it is inserted completely. Poor contact may cause malfunction.

Shut off the external power supply for the system in all phases before mounting or removing the module. Failure to do so may result in damage to the product.

Do not directly touch any conductive part or electronic components of the module.Doing so can cause malfunctions or a failure of the module.

(1) Do not drop or allow any impact to the module case, memory card, terminal block

connector, or pin connector.

(2) Do not remove the printed-circuit board from the module case. Doing so may cause

failure.

4.6.4 Handling of the memory card at power-on

Do not install or remove the memory card while the power is on. If installing or removing the memory card at power-on, the data within the memory card may be corrupted.

POINT

The write protect information of the memory card can be recognized by the CPU module when the programmable controller is powered on or when a CPU module is reset. Note the following.

• When the power supply is turned on with the memory card write protect switch on, the program cannot be written even when the memory card write protect switch is turned off to modify the program. To modify the program, turn off the power supply or reset the CPU module.

• When the power supply is turned off with the memory card write protect switch set to off, the write protect will not function even when the memory card write protect switch is turned on to protect the program. To enable write protection, turn off the power supply or reset the CPU module.

*1 Overcurrent protection

The overcurrent protection device shuts off the 5VDC and/or 24VDC circuit(s) and stops the system if the current exceeding the specified value flows in the circuit(s). As this results in voltage drop, the power supply module LED turns off or is dimly on. After that, eliminate the causes of overcurrent, e.g., insufficient current capacity and short-circuit, and then start the system. When the current value has reached the normal value, the initial start-up of the system will be performed.

*2 Overvoltage protection

The overvoltage protection shuts off the 5VDC circuit and stops the system if the overvoltage of 5.5 to 6.5V is applied to the circuit. This results in the power supply module LED turning off. When restarting the system, power off and on the input power supply, and the initial start-up of the system will be performed. If the system is not booted and the LED remains off, this means that the power supply module has to be replaced.

*3 Allowable momentary power failure period

The allowable momentary power failure period of programmable controller CPUs varies depending on the power supply module used. In case of the A1S63P power supply module, the allowable momentary power failure period is defined as the time from when the primary side of the stabilized power supply for supplying 24VDC to the A1S63P is turned off until when the voltage (secondary side) has dropped from 24VDC to the specified voltage (15.6VDC) or less.

*4 Inrush current

If the power supply module is re-powered on right after powered off (within 5seconds), the inrush current exceeding the specified value (2ms or less) may be generated. Therefore, make sure to repower on the module 5seconds after power off. When selecting a fuse or breaker for external circuit, consider the above point as well as blown and detection characteristics.
