[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) Emergency stop circuits, protection circuits, and protective interlock circuits for conflicting

operations (such as forward/reverse rotations or upper/lower limit positioning) must be configured external to the programmable controller.

(2) When the programmable controller detects an abnormal condition, it stops the operation and all

outputs are:

• Turned off if the overcurrent or overvoltage protection of the power supply module is activated.

• Held or turned off according to the parameter setting if the self-diagnostic function of the CPU module detects an error such as a watchdog timer error.

(3) All outputs may be turned on if an error occurs in a part, such as an 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 "General Safety Requirements" in the MELSEC iQ-R Module Configuration Manual.

(4) Outputs may remain on or off due to a failure of a component such as a relay and transistor in an

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

● In an output circuit, 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.

● 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 manuals relevant to the network. Incorrect output or malfunction due to a communication failure may result in an accident.

● When connecting an external device with a CPU module or intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the program to ensure that the entire system will always operate safely. For other forms of control (such as program modification, parameter change, forced output, or operating status change) of a running programmable controller, read the relevant manuals carefully and ensure that the operation is safe before proceeding. Improper operation may damage machines or cause accidents.

[Design Precautions]

WARNING

● Especially, when a remote programmable controller is controlled by an external device, immediate action cannot be taken if a problem occurs in the programmable controller due to a communication failure. To prevent this, configure an interlock circuit in the program, and determine corrective actions to be taken between the external device and CPU module in case of a communication failure.

● Do not write any data to the "system area" and "write-protect area" of the buffer memory in the module. Also, do not use any "use prohibited" signals as an output signal from the CPU module to each module. Doing so may cause malfunction of the programmable controller system. For the "system area", "write-protect area", and the "use prohibited" signals, refer to the user's manual for the module used.

● If a communication cable is disconnected, the network may be unstable, resulting in a communication failure of multiple stations. Configure an interlock circuit in the program to ensure that the entire system will always operate safely even if communications fail. Failure to do so may result in an accident due to an incorrect output or malfunction.

● To maintain the safety of the programmable controller system against unauthorized access from external devices via the network, take appropriate measures. To maintain the safety against unauthorized access via the Internet, take measures such as installing a firewall.

● Outputs may remain on or off due to a failure of a transistor for external output. Configure an external circuit for monitoring output signals that could cause a serious accident.

[Design Precautions]

CAUTION

● During control of an inductive load such as a lamp, heater, or solenoid valve, a large current (approximately ten times greater than normal) may flow when the output is turned from off to on. Therefore, use a module that has 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.

● Do not power off the programmable controller or reset the CPU module while the setting values in the buffer memory are being written. Doing so will make the data in the flash ROM undefined. The values need to be set in the buffer memory and written to the flash ROM again. Doing so also can cause malfunction or failure of the module.

● When changing the operating status of the CPU module from external devices (such as the remote RUN/STOP functions), select "Do Not OPEN in Program" for "Open Method Setting" in the module parameters. If "OPEN in Program" is selected, an execution of the remote STOP function causes the communication line to close. Consequently, the CPU module cannot reopen the line, and external devices cannot execute the remote RUN function.

● Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 150mm or more between them. Failure to do so may result in malfunction due to noise.

Operation of the ring counter

This function repeatedly counts pulses between the values stored in CH1 Ring counter lower limit value setting (Un\G20 to

Un\G21) and CH1 Ring counter upper limit value setting (Un\G22 to Un\G23). When the ring counter function is selected, an

overflow error does not occur. The preset function and coincidence output function can be used with this function.

Count range of the ring counter

The count range is determined by the relationship between the ring counter lower limit value or ring counter upper limit value

and the value in CH1 Present value (Un\G2 to Un\G3) when CH1 Count enable command (Y4) is turned on or when the preset function is performed. Normally, the count range is Ring counter lower limit value  Present value  Ring counter upper

limit value.

■When the count range is Ring counter lower limit value  Present value  Ring counter upper

limit value (normally used)

• When pulses are counted up, the ring counter lower limit value is automatically stored in CH1 Present value (Un\G2 to

Un\G3) when the present value reaches the ring counter upper limit value.

• When pulses are counted down, even when the present value reaches the ring counter lower limit value, the ring counter

lower limit value is held as the lower limit, and the value of Ring counter upper limit value - 1 is stored in CH1 Present value

(Un\G2 to Un\G3) at the next count-down pulse input.

Both when pulses are counted up and when pulses are counted down, the ring counter upper limit value is not stored in CH1

Present value (Un\G2 to Un\G3). For example, when the count enable command is valid while the ring counter lower limit

value is 0, the ring counter upper limit value is 2000, and the present value is 500, the count range and the present value will

change as follows.

• When pulses are counted up, even when the present value reaches the ring counter lower limit value, the ring counter

lower limit value is held as the lower limit, and the value of Ring counter upper limit value + 1 is stored in CH1 Present value

(Un\G2 to Un\G3) at the next count-up pulse input.

• When pulses are counted down, the ring counter lower limit value is automatically stored in CH1 Present value (Un\G2 to

Un\G3) when the present value reaches the ring counter upper limit value.

Both when pulses are counted up and when pulses are counted down, the ring counter upper limit value is not stored in CH1

Present value (Un\G2 to Un\G3). For example, when the count enable command is valid while the ring counter lower limit

value is 0, the ring counter upper limit value is 2000, and the present value is 3000, the count range and the present value will

change as follows.

■When the count range is Ring counter lower limit value = Ring counter upper limit value

When this condition is established, a value that can be expressed in 32-bit signed binary (-2147483648 to 2147483647) will

be the count range, regardless or the present value.

• While CH1 Count enable command (Y4) is on, even if CH1 Ring counter lower limit value setting (Un\G20 to

Un\G21) and CH1 Ring counter upper limit value setting (Un\G22 to Un\G23) are changed, the high-speed

counter module does not operate with the changed value. Turn off CH1 Count enable command (Y4) before

changing the ring counter upper limit value or ring counter lower limit value.

• Turn off CH1 Count enable command (Y4) before changing the count range using the preset function.

Precautions for using the coincidence output function

When CH1 Coincidence signal enable command (Y2) is turned on before the count is started or while the coincidence output

point setting value and the current value match, the coincidence output is performed. To avoid this status, perform one of the

following operations before turning on CH1 Coincidence signal enable command (Y2).

■Setting different values to the coincidence output point setting value and the current value

Set different values to the coincidence output point setting value and the current value by one of the following methods.

• Changing the coincidence output point setting value

• Changing the current value using the preset function

• Changing the current value by inputting a pulse

■Turning off the counter value coincidence signal

Turn on and off CH1 Coincidence signal No.1 reset command (Y0).

• Since CH1 Present value (Un\G2 to Un\G3) and CH1 Coincidence output point No.1 (Un\G4 to Un\G5) are

0 after the CPU module is powered on or is reset, CH1 Counter value coincident (point No.1) (X2) turns on.

• When CH1 Coincidence signal enable command (Y2) is turned on while CH1 Counter value coincident

(point No.1) (X2) is on, the coincidence output is performed to outside the module. To avoid an incorrect

coincidence output, turn on and off CH1 Coincidence signal No.1 reset command (Y0) before turning on

CH1 Coincidence signal enable command (Y2), and turn off CH1 Counter value coincident (point No.1)

(X2).

Precautions for mounting a remote head module

When a high-speed counter module has been mounted with a remote head module, whether to hold or clear the Y signal at a

disconnection of own station can be set with “CPU error output mode setting” in the module parameter. According to this

setting, whether to continue counting and operate the coincidence output, or to stop counting and not to operate the

coincidence output can be specified.

Setting methods when the parameter is set with “CPU error output mode setting” are described as follows.

• Enable the station-based block data assurance for cyclic data in the sending side.

• To hold the PWM output at a disconnection, select “Hold” for “CPU error output mode setting” in the module parameter.

• To stop the PWM output at a disconnection, select “Clear” for “CPU error output mode setting” in the module parameter.

This setting is valid in module units. The parameter cannot be set in each channel.

A count error may occur when the selected counter function is performed using an external input (A voltage is applied to the

function start input terminal) or using a program (CH1 Counter function selection start command (Y6) is turned on). The

following describes how to calculate the count error.

Count error (max.) when an external input is used

Due to a delay in the input response time of the function start input terminal, the following error occurs.

A Function input response time setting [ms] (1ms maximum) B Pulse input speed [pps] (= Pulse input frequency [Hz]  Multiplication [count])

Count error (max.) when a program is used

Due to a delay in the scan time of the program (Delay of turning on CH1 Counter function selection start command (Y6)), the

following error occurs.

A 1 scan time [ms] B Pulse input speed [pps] (= Pulse input frequency [Hz]  Multiplication [count])

Count error (max.) on the sampling counter function or cycle pulse counter function

A sampling/cycle time error occurs due to an error in design (100ppm) when the sampling counter function or cycle pulse

counter function is performed. The count error is calculated as follows:

A Sampling/cycle time [ms]

B 100 [ppm] C Pulse input speed [pps] (= Pulse input frequency [Hz]  Multiplication [count])

• When no pulse is output from the PWM output point No.2 terminal (EQU2), set 0.

The PWM output starts in the OFF status. When PWM output cycle time - PWM output ON time passes, the PWM output is

turned on. The subtraction of PWM output cycle time - PWM output ON time is performed in the high-speed counter module.

When the result of the subtraction is 0, the PWM output is always on, and when the result of the subtraction is a negative

value, the PWM output is always off.

■Setting condition

Set a value that satisfies all the following conditions. Otherwise, the PWM output is always off.

• PWM output cycle time setting > 0

• PWM output ON time setting > 0

• PWM output cycle time setting  PWM output ON time setting (When this relation is =, the PWM output is always on.)

• When a value other than the setting range described above is set in each of CH1 PWM output cycle time

output ON time setting 2 (Un\G260 to Un\G261), a normal pulse may not be output.

• By using the calculation formula of PWM output ON time = PWM output cycle time  Duty ratio (%)  100,

the PWM output ON time can be calculated based on the duty ratio specified by users.

Precautions for mounting a remote head module

When a high-speed counter module has been mounted with a remote head module, whether to hold or clear the Y signal at a

disconnection of own station can be set with “CPU error output mode setting” in the module parameter. According to this

setting, whether to hold or clear the PWM output can be specified.

Setting methods when the parameter is set with “CPU error output mode setting” are described as follows.

• Enable the station-based block data assurance for cyclic data in the sending side.

• To hold the PWM output at a disconnection, select “Hold” for “CPU error output mode setting” in the module parameter.

• To stop the PWM output at a disconnection, select “Clear” for “CPU error output mode setting” in the module parameter.

This setting is valid in module units. The parameter cannot be set in each channel.

Apply a dummy resistance of several hundred ohms (/several watts) across the pulse input terminals (between 24V and ABCOM).

To shape pulse waveform effectively, increase the load current in cables by inserting a dummy resister of several hundreds 

(/several W) between the pulse input terminals connected to a pulse generator. The greater the load current, the more

effective this method is.

The following figure shows an example of the connection of a dummy resistor at signal level 24VDC:

• Connecting a dummy resister at 24VDC

Shaping a pulse waveform is effective as a countermeasure against the following two cases.

Distance between the pulse generator and the high-speed counter module is long.

The waveform distortion is corrected and the pulse waveform becomes stable.

Waveform is distorted under a noise environment.

The pulse waveform becomes stable by shaping the waveform, which has an effect on external noise reduction.

The following example describes how to evaluate the resistance constant and rated-power of a dummy

resister. For example, if a load current of approximately 30mA is set, the resistance constant of a dummy

resistor is given by: R = V  I = 24V  30mA = 800

and the voltage applied to a dummy resistor is given by: P = V  I = 24V  30mA = 0.72W
