-6100 is a communication protocol converter from DLT645 to Modbus-&RTU. The module supports DLT645-2007 protocol and DLT645-1997 protocol. It reads the data of the meter through the DLT645 interface polling and then stores it in the module cache. The host computer can use Modbus- (network port) and Modbus-RTU (RS485 interface) protocols to read the meter data in the module. The module supports up to 20 meters. This module has 2 data reading modes: "reading from separate meters" and "centralized reading" Functional features: DLT645 meter protocol to network port communication Support Modbus- and Modbus-RTU simultaneous output Active polling to read meter data Support DLT645-2007 protocol and DLT645-1997 protocol Can connect up to 20 meters Support "reading from separate meters": each meter is assigned a fixed register address Support "centralized reading": the register addresses of all meters are read continuously Support rail clip installation and screw fixed installation Note:Due to different factory batches, if there is slight difference in appearance, it not affect the use.
