4.0.58 build 627. June 27, 2024.
The DL-T645-2007 protocol is used in many Chinese multifunction energy meters to unify data exchange between a host computer and meters (for example, it can be a single-phase energy meter or multi-rate watt-hour meter). The plugin implements some parts of the DL-T645-2007 protocol to read current values.
This protocol adopts a half-duplex communication mode with a master-slave structure. A computer or server is a master station that polls multiple watt-hours meters which act as a slave station.
This module has the following features:
- It can read current data from any DL-T645-2007-compatible device.
- The plugin can work with serial and network interfaces.
- It can poll meter data by a custom interval.
- It can poll data from multiple devices at the same time.
