Method writeMultipleCoils

src/ModbusMaster.cpp:471–477

Modbus function 0x0F Write Multiple Coils. This function code is used to force each coil in a sequence of coils to either ON or OFF in a remote device. The request specifies the coil references to be forced. Coils are addressed starting at zero. The requested ON/OFF states are specified by contents of the transmit buffer. A logical '1' in a bit position of the buffer requests the correspondi
