The PN1-D25 series is a Profinet to Modbus RTU gateway used to map Modbus data to Profinet. Use GSD files for integration, code-free reading and writing of Modbus devices, and quickly set up data and transfer it to the PLC. The gateway provides 1 RS485 and 1 RS422 (compatible with RS485) interfaces, each supporting 32 command nodes, a total of 64 command nodes . The PN1-D25 PH supports two RJ45 Ethernet ports and has switch functions . All Modbus commands are loaded in module form , and the memory mapping relationship between Profinet and Modbus is intuitive and can be used in STEP 7 or query in TIA Portal software. You can load the status byte to query the connection status of the Modbus device and monitor the device status in real time .
