sendBit()

Posted by On 02 / 01 / 2019 0 Comment

Description

Sets the arguments as bits to the private array writeData in the ModbusMasterNode class and automatically stacks the data, using beginTransmission with writeMultipleCoils without parameters. writeData is the content of a Modbus packet using the Write function code.

Syntax

node1.sendBit(value)

Parameters

node1: ModbusMasterNode object.

value: Fill in the Boolean value of the writeData array, i.e. the content of the Modbus packet to be sent.
