As everybody knows, PLC industrial control industry engineers will meet the back to hang multiple RTU terminal equipment, PLC program to deal with the modbus polling, CRC16, high and low byte, round round halo around people, even if the program is written, the scene debugging when also will meet all kinds of situation, it is difficult to find problems, here to talk about modbusRTU485 profinet gateway, you can take bus 485 meters, temperature controller, inverter, weighing instrument and so on to profinet agreement,

Today introduced a unique both HJ6307, HJ6311 models of Profinet gateway, respectively is to support the 7 or 11 road independent modbusz Profinet gateway, without programming, polling time shorter, acquisition time faster, and is especially suitable for use at the same time multiple RTU equipment automation control system adopts,
