1. Adding multiple coils or registers to read.
Read analog input (0x04)
Host sends:Addr 04 regH regL NumH numL crcH crcL
From the machine back:Addr 04 len d0H d0L...DnH dnL crcH crcL
Interpretation: Register address from0Start counting.numH numLRepresents the number of routes of the analog quantity to be read. This card has 5 analog input channels.12bitADCEach analog takes up two bytes of data. For example, to read the2Lu He3The register address is0001The number of registers is0002 For example, to read all analog quantities1Lu Zhi di8The address of the register is uuuuuuuuuuuuu0000The number of registers is0008 Return data0-0xFFFRepresents the collected analog quantities, such as analog quantities.0-20mAThe data read are18CThe decimal number is396So the current value isI = 20mA*396/1023 = 7.742mA Sensors are generally4-20mAIf the reading value is less than4mAThe connection line is faulty.
Example: read the first1Lu Zhi di8Road analogue
