Arduino Master Slave RS485 MODBUS RTU Schneider electric EasyLogic PM2200 PM2300

[@omarinth]

สอบถามหน่อย ครับ กรณีอ่านค่าเป็น INT64 เขียนคำสั่ง ยังไงครับ

[@nosoloreal8486]

modbus จะมีรูปแบบการ เรียก Address สองแบบครับ modbus address และ plc address มันจะเหลื่อมกัน 1 ครับ

พี่ครับผมขอโค๊ดหน่อยครับสนใจศึกษาครับ

[@salmana35]

hello sir connection mod bus fail could not connected the result =node.ReadHoldingRegisters(REg,2);

[@fredybellido5289]

are you created library REG PM 2200???

[@saadpatel8572]

Sir between Arduino and the energy meter the TTL what is its name and purpose.... Please inform sir!!

i try this code i get error of ResponseTimedOut

[@rayhannafis5701]

error to connect modbus register.
can you help me to solve it?

[@ยศสรัลแป้นเพ็ชร-ธ3ฑ]

มีโค้ดให้ลองใช้ไหมครับ

Hi, I need to read that data from a similar meter EM6436H from Schneider. Can you please share the code. I am not very good at RS485 Modbus communication.
