What is the access characteristic for Modbus 'Coils' register type?
Answer
Read/Write status bits
Coils are defined within the Modbus data structure as representing single digital outputs whose status bits can be both read from and written to by the master device. In practical industrial application, this register type is typically used for controlling outputs, such as issuing a command to start or stop a pump. They are specifically defined as 1-bit elements, differentiating them from the 16-bit values found in Input Registers and Holding Registers.
