3.4.11Offset/gain setting mode (buffer memory addresses 22, 23: Un\G22, Un\G23)

(1)Specifies the channel to be adjusted for the offset/gain settings.

(2)The channel for which the offset is to be adjusted is specified in buffer memory address 22 (Un\G22) and the channel for which the gain is to be adjusted is specified in buffer memory address 23 (Un\G23).

(3)Although it is possible to set multiple channels at the same time, set the offset and gain separately (buffer memory addresses 22 and 23: Set either Un\G22 or Un\G23 to 0). If both are set at the same time, an offset/gain setting mode error (error code 500) occurs.

(4)For Q64AD, b4 to b7 (information for CH5 to CH8) are invalid.

(5)See Section 4.6 for the details of the offset/gain settings.

3.4.12Maximum and minimum values storage area (buffer memory addresses 30 to 45: Un\G30 to Un\G45)

(1)The maximum and minimum values of the converted digital value for each channel are stored.

(2)The stored values for all channels will be cleared to 0 when the operating condition setting request (Y9) is set to ON and the setting is changed or when the maximum and minimum values reset request (YD) is set to ON.

(3)The maximum and minimum values are stored for each sample processing time (measurement), even with channels for which averaging processing is specified.

Q68ADV, Q68ADI, Q64AD specifications

Mitsubishi Electronics, a renowned leader in automation technology, has developed advanced analog input modules that play a crucial role in numerous industrial applications. Among them, the Q64AD, Q68ADI, and Q68ADV models stand out with their impressive features and capabilities tailored for precise data acquisition and control.

The Q64AD module is designed for high-performance analog signal processing. It offers up to 16 channels of differential input, making it suitable for applications requiring multiple sensor readings simultaneously. The resolution of 16 bits enables accurate data capture, ensuring that subtle variations in process variables, such as temperature or pressure, are detectable. One of its key advantages is the high-speed sampling capability, allowing data collection at rates of up to 100 milliseconds per channel, essential for real-time monitoring in fast-paced environments.

In contrast, the Q68ADI model enhances the versatility of the analog input system. It includes built-in isolators, providing additional protection against noise and interference commonly found in industrial settings. This isolation feature improves the reliability of sensor readings, especially in harsh environments where electrical noise can impact performance. Furthermore, the Q68ADI supports both voltage and current input types, making it adaptable to various sensor configurations, such as thermocouples and RTDs, expanding its usability across different applications.

The Q68ADV module takes versatility a step further by integrating advanced diagnostic features. This model offers a range of additional functions, including built-in fault detection and self-diagnosis capabilities that identify issues before they escalate into significant problems. It also features temperature compensation and linearization algorithms, which enhance the accuracy of reading from thermocouples and other temperature sensors. The Q68ADV module is ideal for applications demanding high reliability and stringent performance standards, making it indispensable in industries like pharmaceuticals and food processing.

All three models are designed to seamlessly integrate with Mitsubishi's PLC systems, ensuring smooth communication and data exchange. They support various protocols, making them compatible with a wide range of devices and systems. Collectively, the Q64AD, Q68ADI, and Q68ADV modules exemplify Mitsubishi Electronics' commitment to delivering high-quality, reliable, and innovative solutions in industrial automation, empowering businesses to achieve greater efficiency and operational excellence.
