Page 3: Safety Precautions
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 [Precautions for using the channel isolated analog-digital converter modules in SIL2 mode] ● When the R60AD8-G detects a fault in the external power supply or programmable controller, a digital operation value becomes an OFF value (equivalent to 0V/0mA) in all channels. Configure an external circuit to ensure that the power source of a hazard is shut off when a digital operation value of the R60AD8-G is an OFF value (equivalent to 0V/0mA).
Page 6 [Installation Precautions] WARNING ● Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may result in electric shock or cause the module to fail or malfunction. [Installation Precautions] CAUTION ●...
Page 7 [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 8 [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 9 [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 10 [Operating Precautions] CAUTION ● When changing data and operating status, and modifying program of the running programmable controller from an external device such as a personal computer connected to an intelligent function module, read relevant manuals carefully and ensure the safety before operation. Incorrect change or modification may cause system malfunction, damage to the machines, or accidents.

Page 58: Difference Conversion Function
1.10 Difference Conversion Function This function subtracts a difference conversion reference value from a digital operation value and stores the acquired value in the buffer memory area. The digital operation value at the start of this function is treated as 0 (reference value). Thereafter, values that increased or decreased from the reference value are stored in the buffer memory.
Page 59 ■Operations of when an input signal error occurs When an input signal error occurs, even if 'CH1 Difference conversion trigger' (Un\G470) changes from No request (0) to Trigger request (1), the difference conversion does not start. After the input signal error returns to the normal value, change 'CH1 Difference conversion trigger' (Un\G470) from No request (0) to Trigger request (1) again.
Page 60 ■Operations of when 'Operating condition setting request' (Y9) is turned on and off • During the difference conversion, even when 'Operating condition setting request' (Y9) is turned on and off, the difference conversion continues without updating the difference conversion reference value. To updating the difference conversion reference value, restart the difference conversion by changing CH1 Difference conversion trigger (Un\G470) from Trigger request (1) to No request (0), and Trigger request (1) again.
Page 61 ■Operations of CH1 Maximum value (Un\G404) and CH1 Minimum value (Un\G406) When the difference conversion starts, the maximum value and the minimum value of the values acquired by the difference conversion are stored in 'CH1 Maximum value' (Un\G404) and 'CH1 Minimum value' (Un\G406). By turning on 'Maximum value/minimum value reset request' (YD), the maximum value and the minimum value after the start of the difference conversion can be checked.
Page 62: Maximum Value/Minimum Value Hold Function
1.11 Maximum Value/Minimum Value Hold Function This function stores the maximum and minimum values of digital operation values in the buffer memory area for each channel. Time average and count average are processed on the averaging process cycle. The values of the sampling processing, moving average, and primary delay filter are updated on the sampling cycle.
Page 63: Logging Function
1.12 Logging Function This function logs (records) digital output values or digital operation values. Data of 1000 points can be logged for each channel. Logging data are stored in the buffer memory area. In addition, the data collection can be stopped by using the status change of the data as a trigger.
Page 64 CH16 Un\G25000 to Un\G25999 *1 When the R60AD8-G is used, data is stored in CH1 to CH8. If logging has been performed even once, all the logging data above are cleared to 0 at the timing when 'Operating condition setting request' (Y9) is turned off and on.

Buffer memory area Value status 'CH1 Head pointer' (Un\G434) Values are initialized. 'CH1 Latest pointer' (Un\G435) 'CH1 Number of logging data' (Un\G436) 'CH1 Trigger pointer' (Un\G437) 'CH1 Trigger generation time' (Un\G444 to Un\G448) 'CH1 Logging data' (Un\G10000 to Un\G10999)
Page 71: Logging Hold Request
Logging hold request A hold trigger is generated from a program at any timing. Logging starts when ON (1) is set to 'CH1 Logging hold request' (Un\G471) and stops after a preset number of the data is collected. Controlled by the A/D converter module 'CH1 Logging hold request' OFF(0) ON(1)
Page 72: Level Trigger
Level trigger When a value in the monitored buffer memory area of the A/D converter module satisfies a preset condition, a hold trigger is generated. A level trigger is monitored on the refreshing cycle of the digital output value or the digital operation value. Initial setting of a level trigger ■Setting a target to be monitored As a condition to generate a hold trigger, set the buffer memory address to be monitored to 'CH1 Trigger data' (Un\G541).
Page 73 ■Setting the monitoring condition Set a condition to generate a hold trigger in 'CH1 Level trigger condition setting' (Un\G540). Setting value Description Rise (1) A hold trigger is generated under the condition Stored value of a buffer memory area to be monitored (a).
Page 74 Operation of a level trigger To use a level trigger, set ON (1) to 'CH1 Logging hold request' (Un\G471) in advance. At the point where ON (1) has been set to 'CH1 Logging hold request' (Un\G471), the module becomes the trigger condition wait status. Data collection starts when the trigger condition has been satisfied, and stops when the set points of the data have been collected.
