how to programing delta plc and him for weigh controller To program a Delta PLC to function as a weigh controller, you need to follow these general steps: Connect the load cell: Connect the load cell to the PLC's analog input module. Make sure that the load cell is properly calibrated and that the signal is within the input range of the analog input module. Configure the analog input: Configure the analog input module in the PLC according to the load cell specifications (e.g. input range, sample rate, etc.). Convert the analog signal: In the PLC program, use an analog-to-digital (A/D) conversion function to convert the analog signal from the load cell into a digital value that can be processed by the PLC. Filter the signal: Apply signal filtering to the digital value to eliminate any noise or fluctuations in the signal. Calculate the weight: In the PLC program, use the filtered digital value to calculate the weight of the material on the scale. Display the weight: Use the PLC'
