PROFIBUS-DP to Modbus-RTU protocol converter KWDPM01 gateway is a PROFIBUS-DP turn to Modbus-RTU protocol converter. It can achieve the protocol conversion between PROFIBUS-DP and Modbus-RTU. Whoever has the RS232/485 interface Modbus RTU - protocol devices can make use of the product realization interconnection with field bus profibus-dp.Such as: With the Modbus RTU protocol interfaces of the inverter ,Motor start protection devices, Smart high-low voltage electrical appliances, Power measurement device, measuring equipment and intelligent field instrumentation and so on. The instructions 1.If you are already familiar with Modbus-RTU protocol configuration software Siemens Step7 need to use this module, see the first chapter "Step7 use this module" sample. 2.If you need A B B AC800F configuration software using the Control Builder F this module see the second Chapter "A B B Control Builder F using this module" sample. 3.If you are not already familiar with Modbus-RTU protocol, see Chapter III: Modbus-RTU protocol profile, you only need to know that you are using function code can be. 4.If you are new Profibus-DP and Modbus-RTU, please read through this manual. Technical parameters 1, The installation method: 35mm rail mounting 2, DP communication speed: 9.6Kbps ~ 12Mbps 3, Supports Modbus Number of Sites: 32 4, Working voltage: DC 24V 5, The working environment temperature: -25 ~ 75 ° 6, Storage temperature: -40 ~ 80 ° 7, Relative humidity: ≤ 90% (non-condensing) 8, Protection: IP20 Hardwired 1.As shown, the top of the module that the power supply and RS485 terminals, positive is the status indicator, Profibus-DP address setting DIP switches (16 hex) and Profibus-DP interface. 2.If the address is the high DIP switch 1, Address Low DIP switch 6, the setup of the module in the DP network address 1 * 16 +6 is 22. 3.Under normal circumstances KWDPM01 Gateway LED states: PW: Power light lit. DP: DP status, DP communication is normal then destroy, otherwise flashing. TX:Modbus master station transmits light, normal, flicker, frequency 2HZ more. RX: Modbus master station receives light, normal, flashing frequency 2HZ more. Typical applications network diagram
