How to take analog value from analog card in Mitsubishi plc for load cell value
We have a setup for Printer, Load cell and scanner which will be configured with FX5u series PLC, so my question is how to get analog data and which special register to get analog input and how to get printed the same data in printer
- Connect the Devices: Ensure that the load cell, scanner, and printer are properly connected to the FX5U PLC. The load cell will typically connect to an analog input module, while the scanner and printer may connect via digital inputs/outputs or a communication module.
- Read Analog Input Data: For the load cell, configure an analog input channel on the FX5U PLC using the appropriate analog input module. The FX5U PLC supports various types of analog input modules, so refer to the specific module’s manual for wiring and configuration instructions. Once configured, you can read the analog input data from the corresponding special register in the PLC. The special register address will depend on the configuration of your analog input module.
- Process Data: After reading the analog input data, you may need to process it according to your application requirements. This could involve scaling, filtering, or performing other calculations to convert raw sensor data into meaningful measurements (e.g., weight).
- Control the Printer: To print data from the PLC, you’ll need to interface with the printer. Depending on the type of printer you’re using (e.g., thermal, dot matrix), you may need to send commands or data in a specific format. This typically involves using communication protocols such as RS-232, RS-485, Ethernet, or USB, depending on how the printer connects to the PLC. Refer to the printer’s manual for communication protocol details and command format.
- Send Data to the Printer: Once you have the data you want to print, format it according to the requirements of your printer and send it using the appropriate communication method. This could involve sending ASCII text, binary data, or printer-specific commands depending on the printer model and protocol.
