With the help of the Ethernet/IP protocol, it can quickly access the industrial Ethernet, build a large-scale industrial automation network with upper computer monitoring systems and other automation equipment, and realize remote monitoring and centralized management.

5. I/O Port Configuration: It is equipped with rich input and output ports, including various types. For example, it has digital input and output ports, which can be used to collect switching signals of external equipment, such as the start-stop status of equipment, limit switch signals, etc., and control the switching actions of external equipment, such as relays, solenoid valves, etc. At the same time, it may integrate analog input and output ports, which can process continuously changing analog signals, such as voltage signals of temperature sensors, current signals of pressure transmitters, etc., to accurately monitor and adjust analog parameters in the industrial production process.

1. High-Precision Motion Control: Using advanced motion control algorithms and high-performance processors, DNC115 can achieve precise control of the motion axes of equipment. In machine tool processing applications, it can realize fast and smooth motion trajectory control such as linear interpolation and circular interpolation, ensuring that the tool or workpiece moves accurately according to the preset path, processing complex geometric shapes, and meeting the strict requirements of precision processing for motion accuracy.

2. Reliability and Stability: In terms of hardware design, high-quality electronic components are selected, which have undergone strict screening and testing to ensure hardware reliability. At the software level, a mature and stable operating system and control program are adopted, with a complete error detection and handling mechanism. Even in complex environments with strong electromagnetic interference and power fluctuations in industrial sites, it can operate continuously and stably, effectively reducing production interruptions caused by equipment failures and improving production efficiency.

3. Flexible Expandability: The modular design architecture endows DNC115 with strong expansion capability. Users can flexibly add or replace functional modules according to actual project needs. For example, when it is necessary to increase analog acquisition channels, an analog input module can be conveniently inserted; if it is necessary to expand the number of equipment controlled by digital output, a digital output expansion module can be installed. This flexible expansion method can easily meet the needs of functional upgrading of the control system due to changes in industrial production scale and process improvement at different stages.

4. Convenient Communication Function: Thanks to the support of multiple communication protocols, DNC115 can be seamlessly integrated with other equipment in the industrial network. On the one hand, it can upload the operating status of equipment, production data, etc. to the upper computer system of the monitoring center in real time. Operators can clearly understand the operating status of equipment remotely through the upper computer software and find potential problems in time. On the other hand, it can quickly receive control commands from the upper computer, such as modifying equipment operating parameters, starting or stopping equipment, etc., realizing remote control and management, and greatly improving the automation and intelligence level of industrial production.

5. Self-Diagnosis Function: With a built-in comprehensive self-diagnosis mechanism, DNC115 can monitor its own hardware status and program operation in real time. Once a hardware failure is detected, such as chip overheating, memory error, etc., or an abnormality in program operation is found, such as logical error, infinite loop, etc., it will immediately output a fault alarm signal and record detailed information such as the time and type of the fault. This provides a strong basis for maintenance personnel to quickly locate and eliminate faults, significantly shortening equipment downtime and reducing production losses.

1. Power Fault

• Causes of Fault: The external power supply may be unstable, with voltage exceeding the normal range; the power connection line is loose, open, or short-circuited; the internal power circuit of the module is faulty, such as damaged power chips, capacitor leakage, etc.

• Solutions: Use a multimeter to detect the external power supply voltage to ensure that it is within the normal fluctuation range of 220V AC. Check the power connection lines, re-plug and fix them, and repair open or short-circuited lines. If the internal power circuit of the module is suspected to be faulty, contact professional maintenance personnel for inspection and repair, and replace the damaged power module if necessary.

2. Communication Fault

• Causes of Fault: The communication cable is damaged or the connector is loose; the communication protocol setting is incorrect and does not match other equipment; the hardware of the module's communication interface is faulty, such as a damaged communication chip.

• Solutions: Carefully check the communication cable, replace the damaged cable, and fasten the loose connector. Recheck the communication protocol, baud rate, node address and other parameters to ensure they are consistent with the communication object. If it is confirmed that the communication interface hardware is faulty, the communication interface module needs to be replaced or returned to the manufacturer for repair.

3. I/O Port Fault

• Causes of Fault: The input port may be damaged due to excessive external signals, short circuits, etc.; the output port may be burned due to excessive load or short circuits.

• Solutions: For input port faults, check the external input signal source to eliminate signal abnormalities. Use a multimeter to detect the electrical performance of the input port. If it is damaged, try to replace the chip or circuit module corresponding to the input port. For output port faults, check whether the load is overloaded and remove the overloaded or short-circuited load. If the output port is damaged, replace the corresponding output circuit components as well.

4. Abnormal Control Precision

• Causes of Fault: Incorrect setting of motion control parameters; faults in the motor or transmission mechanism, such as motor step loss, loose transmission belt, etc.; sensor faults, such as abnormal encoder signals.

• Solutions: Recheck and adjust the motion control parameters to ensure that the parameter settings meet the actual operating requirements of the equipment. Check the motor and transmission mechanism, repair or replace faulty parts, such as adjusting the tightness of the transmission belt, repairing or replacing the motor with step loss. Check the sensor, such as the encoder, replace it if it is damaged, and check whether the installation position of the sensor is correct to ensure normal signal transmission.
