Dec 13, 2018 · Modbus Function Code 1 (Hex 0x01) This function code is used by TOP Server when requesting a read of one or more (up to 2000 at a time) output coils or 0xxxxx type discrete/boolean addresses. Output coils are read/write access - you'll see support for Function Codes 5 and 15 a further down the list.
One Register has 16 bit, a word. If you want to read so a double register with your modbus software, then must you address with the start address of the double register, in this case 30777. If you read it with the start address 30778, then read you one word of the double register 30777 (the right word) and one word of the double register 30779. For serial connection you may need an USB to RS485, or an RS232 to RS485 converter.

For 40001 to 40012, then a start address of 0 and a quantity of 12 is correct..

The Modbus specification says “Registers are addressed starting at zero. Therefore input registers numbered 1-16 are addressed as 0-15.”. Unfortunately, that means a register documented with an address of 1221 (Frequency) must be requested by sending an address of 1220 (04C4 hex) to the WattNode. Most application software will automatically.
We have daily contact with customers worldwide who fulfill their dreams of wood. These three parameters are exported via a Modbus Slave module to Modbusregisters 40011, 40012 and 40013, with a scalin g factor of 10. In accordance with the Modbus protocol, register 40011 is number ed as 10 when.
Modbus Write Multiple Registers (16). I use Node Red and Modbus Write / Modbus Flex Writer but cannot seem to get all the info / syntax to the particular address correct. Thanks @innesleroux could you let us know if you used a Deye or a Sunsynk, I am trying to figure out if the Deye invertes use the same protocol as the the Sunsynk document.
#2. Coils and registers are just names for memory addresses. The other way to look at it is that they are just pre-defined variable names. A coil is a boolean (bit) variable, and a register is an
