1451 Smart Sensor CommandTEDS schema Each arg element is one element in the argumentArray that will be sent as part of the command. Each reply element is one element in the argumentArray that will be returned as part of the reply to the command. The attribute replyArgOffset gives the number of octets from the beginning of the reply message to the first octet in this argument. This field provides an offset in octets from the beginning of the reply message to the first octet of this value. This field provides an array of octets. The exact structure and meaning of the elements of this array is defined in the desc attribute or by reference to another document. The mask allows a bit or bits to be selected from the reply argument. This can be repeated as many times as required by specifying the same replyArgOffset repeatedly. A one in a bit position in the mask selects the bit and a zero rejects that bit.
