SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the MELSEC iQ-R Module Configuration Manual.
Page 4 [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.
Page 5 [Design Precautions] WARNING ● 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. Incorrect output or malfunction due to a communication failure may result in an accident.
Page 6 [Design Precautions] CAUTION ● Do not install the control lines or communication cables together with the main circuit lines or power cables. Doing so may result in malfunction due to electromagnetic interference. Keep a distance of 100mm or more between those cables. ●...
Page 7 [Security Precautions] WARNING ● To maintain the security (confidentiality, integrity, and availability) of the programmable controller and the system against unauthorized access, denial-of-service (DoS) attacks, computer viruses, and other cyberattacks from external devices via the network, take appropriate measures such as firewalls, virtual private networks (VPNs), and antivirus solutions.
Page 8 [Wiring Precautions] WARNING ● Shut off the external power supply (all phases) used in the system before installation and wiring. Failure to do so may result in electric shock or cause the module to fail or malfunction. ● After installation and wiring, attach a blank cover module (RG60) to each empty slot and an included extension connector protective cover to the unused extension cable connector before powering on the system for operation.
Page 9 [Wiring Precautions] CAUTION ● Individually ground the FG and LG terminals of the programmable controller with a ground resistance of 100 ohms or less. Failure to do so may result in electric shock or malfunction. ● Use applicable solderless terminals and tighten them within the specified torque range. If any spade solderless terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure.
Page 10 [Startup and Maintenance Precautions] WARNING ● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. ● Correctly connect the battery connector. Do not charge, disassemble, heat, short-circuit, solder, or throw the battery into the fire. Also, do not expose it to liquid or strong shock. Doing so will cause the battery to produce heat, explode, ignite, or leak, resulting in injury and fire.
Page 11 [Startup and Maintenance Precautions] CAUTION ● 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.

Page 21: Part 1 Normal Mode
PART 1 NORMAL MODE This part consists of the following chapters. These chapters describe the details on using the I/O module with diagnostic functions in normal mode. 1 FUNCTIONS 2 PARAMETER SETTINGS 3 TROUBLESHOOTING APPENDICES (NORMAL MODE)
Page 22: Chapter 1 Functions
FUNCTIONS Input Function This function takes in the ON/OFF state of external inputs. However, when the input response time setting function or input delay function is enabled, the ON/OFF state of the input signals in the module (X0 to XF) and the ON/OFF state of the actual external inputs (X00 to X0F) may not match. The following figure shows the processing procedure of the input function.
Page 23: Input Response Time Setting Function
Input response time setting function This function allows changing the input response times of the input module with diagnostic functions for each input. The input module with diagnostic functions takes in external inputs with the set input response times. External input (X0) Input signal in the module (X0) t: Input response time Setting procedure...
Page 24: Input Hold/Clear Function
Input HOLD/CLEAR function This function allows setting whether to hold or clear the input status just before an error (alarm, minor error, or moderate error) when the error is detected in the input module with diagnostic functions. Depending on whether "Input HOLD/CLEAR function enable/disable" is enabled or disabled, the input module with diagnostic functions operates differently when an error is detected.
Page 25 Operation of when "Input HOLD/CLEAR function setting" is set to "HOLD" • When the external input remains on 'Error flag' (X10)/'Alarm flag' (X11) External input (X0) Input to the CPU module (X0) • When the external input turns off 'Error flag' (X10)/'Alarm flag' (X11) External input (X0) Input to the CPU module (X0) Setting procedure...
Page 26: Input Delay Function
Input delay function This function allows changing the status of an X signal in the module after a certain time (input delay time) elapsed when the status of the external input changes. The input delay function has the following three functions. •...
Page 27 ON delay When an external input turns on, this function turns on the X signal after a certain time (input delay time) elapsed. When the input delay time is set to a value larger than the scan time while the ON delay is used, the program can recognize that the external input turns off even if its OFF time is short.
Page 28 Pulse stretch When a status change of an external input is detected, this function can hold the signal status before the change for a certain time (input delay time) from the change. (When a status change of an external input is detected, the external input is not taken in until a certain time has elapsed from the change.) After a certain time has elapsed, taking in the external input starts.
Page 29: Number Of Input On Times Integration Function
Number of input ON times integration function This function counts the number of times that an external input turns on. When the number of input ON times alarm detection count has been set and the number of input ON times reaches the set value, an alarm occurs.
Page 30 Number of input ON times alarm detection notification To use the number of input ON times alarm detection notification, set "Number of input ON times alarm detect setting" to "To detect" and set "Number of input ON times alarm detect count setting". When the number of input ON times reaches the number of input ON times alarm detection count (set value), an alarm (Number of input ON times alarm detection count reached) occurs.
Page 31 Clearing the number of input ON times The number of input ON times can be cleared with 'Number of input ON times value clear request' (Un\G3584). Each bit of 'Number of input ON times value clear request' (Un\G3584) corresponds to each input. When the bit corresponding to the input to be cleared is changed from 0 (Not requested) to 1 (Requested), the value of 'Number of input ON times' (Un\G2848 to Un\G2879) is cleared and 1 (Completed) is stored in 'Number of input ON times value clear completed' (Un\G2880).
Page 32: Event Time Stamp Function
Event time stamp function This function records the time data when an input status changes. When this function is used, the events in the entire system can be recorded in the correct order of occurrence based on the time data and time stamp value recorded individually by the input module with diagnostic functions. This record helps investigate a cause when a trouble occurs.
Page 33 Event time stamp data Collected event time stamp data is stored in Event time stamp data (Un\G4608 to Un\G5375). After Event time stamp data (Un\G4608 to Un\G5375) becomes full, the data is overwritten from the first data area. Event time stamp data 1st data 2nd data 3rd data...
Page 34 Setting for not-refreshed data Whether to overwrite the event time stamp data which have not been read can be set for when an external input status changes 128 times or more before the CPU module refreshes the event time stamp data. •...
Page 35: Output Function
Output Function This function outputs the output data specified by the CPU module to the external device without any change. However, when the output delay function is enabled, the ON/OFF state of Y signals (Y0 to YF) and the ON/OFF state of the external outputs (Y0 to YF) may not match.
Page 36: Output Delay Function
Output delay function When the status of an output signal from the CPU module is changed, this function changes the status of the external output after a certain time (output delay time) elapsed. The output delay function has the following two functions. •...
Page 37 ON delay When an output signal from the CPU module is turned on, this function turns on the external output after a certain time (output delay time) elapsed. The OFF state of an external output can be held for a certain time by using the ON delay even if the output signal from the CPU module is turned on.
Page 38: Number Of Output On Times Integration Function
Number of output ON times integration function This function counts the number of times that an output from the CPU module turns on. When the number of output ON times alarm detection count has been set and the number of output ON times reaches the set value, an alarm occurs.
Page 39 Number of output ON times alarm detection notification To use the number of output ON times alarm detection notification, set "Number of output ON times alarm detect setting" to "To detect" and set "Number of output ON times alarm detect count setting". When the number of output ON times reaches the number of output ON times alarm detection count (set value), an alarm (Number of output ON times alarm detection count reached) occurs.
Page 40 Clearing the number of output ON times The number of output ON times can be cleared with 'Number of output ON times value clear request' (Un\G3840). Each bit of 'Number of output ON times value clear request' (Un\G3840) corresponds to each output. When the bit corresponding to the output to be cleared is changed from 0 (Not requested) to 1 (Requested), the value of 'Number of output ON times' (Un\G3136 to Un\G3167) is cleared and 1 (Completed) is stored in 'Number of output ON times value clear completed' (Un\G3168).
Page 41: Common Functions Of The I/O Module With Diagnostic Functions
Common Functions of the I/O Module with Diagnostic Functions This section describes the functions common to the input module with diagnostic functions and the output module with diagnostic functions.
