Function codes for Modbus

Function codes are explained in detail.
In this chapter, function fields and data fields varying by function codes are explained.
Each actual message frame consists of an address field, function field, data field, and error check
field, which are transmitted in this order.

List of function codes

01 (0x01) Read coils

ON/OFF states of slave coils are read.
Since this is a read command, no broadcast can be specified.
Specify the coil start address and number of coils.

* N = Number of coils/8 or N = N + 1 if indivisible

Example) Read the digital zero (address 00003) state.
