8 DL/T-645Communication Guideline

It mainly specifies how to resort to the software to control the instrument series via the communication port. The user
shall have knowledge of DL/T645-1997 Communication Protocol and thoroughly read all other contents herein
before a relatively comprehensive understanding on the functions and applications of the product. In the meantime,
set communication port 2 as DL/T-645 Protocol. This chapter includes: DL/T645-1997 Protocol Overview, detailed
explaination on the communication application format, aplication details and parameters address table of the
instrument.

8.1 DL/T645-1997 protocol overview

his instrument conforms to DL/T645-1997 Communication Protocol. DL/T645-1997 Communication

Protocol specifies in detail the calibration code, data, sequence, etc, which are indispensable to the specific
data exchange. DL/T645-1997 Communication Protocol uses master-slave response connection (half
duplex) in one communication line. It means bidirectional transmission along one standalone
communication line. First, the host computer signal retrieves unique terminal equipment (slave), and then,
the response signal sent by the terminal equipment is transmitted to the host in the opposite direction.
DL/T645-1997 Protocol only allows communication between host (PC, PLC, etc) and terminal equipment
instead of exchange of data in between the standalone terminal equipment. Thus, the terminal equipment
will not occupy communication line during initializing. Instead, it's only limited to response to the
corresponding enquiry signal.

8.2

Transmission mode

The transmission mode represents one series of independent data structure within one data frame

and the limited rules for data transmission. Definitions of transmission mode compatible with DL/T645-1997
Protocol

–

RTU mode are as follows.

each byte bit
1 initial bit
8 data bits; the smallest effective bit will be sent firs
1 even calibration bit
1 stop bit
