MBus M-BUS to MODBUS-RTU converter RS485 can connect to 500 MBus meter support transparent transmission

1.2 Product introduction

This is a high-performance dual converter with bus interface and communication protocol. On the bus interface, the conversion of M-BUS bus to RS485 bus is realized. In the communication protocol, CJ/T-188, the European standard first-level address MBUS protocol, the European standard second-level address MBUS protocol, and the user-defined protocol to standard MODBUS-RTU are realized. The user can obtain the data of various MBUS meters connected to the GL102 converter by reading the registers with the MODBUS-RTU protocol through the RS485 interface.

The converter realizes the conversion function of the physical layer and the protocol layer at the same time. Its built-in isolation circuit can effectively protect the equipment connected to the serial port. It has multiple protection and filtering processing on the M-BUS end, which can provide stability, safety and anti-interference ability. Strong M-BUS communication; widely praised in thousands of engineering practices and actual use.

This converter is suitable for any MODBUS master station to read the data of M-BUS equipment. The converter supports the reading of 100 meter data under the MODBUS-RTU protocol. At the same time, the converter also supports the transparent transmission mode. The transparent transmission mode can realize the transparent transmission between the host and the M-BUS slave. The transparent transmission mode supports up to 500 meters.

Instruments that support standard protocols can also be customized to read the data of other M-BUS instruments and devices according to the actual needs of users, and support program upgrades through the converter serial port.
