BL122
Modbus to PROFINET Protocol Converter
The Modbus to PROFINET gateway BL122 is an industrial protocol conversion device designed to achieve seamless communication between the Modbus protocol (including Modbus RTUand Modbus TCP) and the PROFINET protocol. In the field of industrial automation, it can easily convert sensor and device data into PROFINET protocol and connect to PLC. Key
