This chapter includes a brief description of the DL/T645-1997 protocol, a detailed explanation of the communication application format, details of the application of the machine and the parametric address table. Protocol Overview 8.1 DL/T645-1997 The instrument uses a communication protocol that complies with the DL/T645-1997 specification, which defines in detail the checksum, data, sequence, etc., that are necessary for a particular data exchange.The DL/T645-1997 protocol uses a master-slave answering connection (half-duplex) on one communication line, which means that signals are transmitted on a single communication line along two opposite directions.
