Electric power: It is used for process control in power plants, such as boiler control and turbine monitoring.
Water treatment: It monitors water quality parameters such as pH value, turbidity, and flow rate to ensure the effectiveness of the water treatment process.
Common Faults and Solutions
Channel failure: The phenomenon is that a certain input channel cannot collect signals normally or the collected data is abnormal. The reasons may be damage to the channel hardware, poor wiring, or software configuration errors. The solution is to check whether the wiring of the channel is firm, and whether there are loose connections or open circuits; reconfirm whether the configuration parameters of the channel in the software are correct; if the hardware is damaged, contact professional maintenance personnel or replace the module.
Communication failure: If there is a communication interruption or error between the module and the control system. The reasons may be communication line failures, inconsistent communication protocol settings, or damage to the communication interface of the module. To solve this, check whether the connection of the communication line is normal, and whether there are damages or poor contacts; confirm that the communication protocol settings are consistent with those of the control system; check whether the communication interface has physical damage, and if so, repair or replace it.
Large measurement error: If the deviation of the measurement result from the actual value exceeds the allowable range. The reasons may be inaccurate sensor calibration, the influence of external interference, or incorrect settings of the zero point and range of the module. In this case, recalibrate the sensor; check the shielding and grounding of the equipment to eliminate external interference; confirm whether the settings of the zero point and range of the module are correct, and if incorrect, reset them.
