We produce Profibus Modbus converterWe produce such profibus interface and profibus cable, profibus connector since the year 2004.80% profibus projects use our products in China.Please contact us for more information about profibus module.KW-DPM01 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.Ø 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.Ø If you need ABB AC800F configuration software using the Control Builder F this module see the second Chapter "ABB Control Builder F using this module" sample.Ø 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.Ø If you are new Profibus-DP and Modbus-RTU, please read through this manual.Technical parameters1, The installation method: 35mm rail mounting2, DP communication speed: 9.6Kbps ~ 12Mbps3, Supports Modbus Number of Sites: 324, Working voltage: DC 24V5, The working environment temperature: -25 ~ 75 ℃6, Storage temperature: -40 ~ 80 ℃7, Relative humidity: ≤ 90% (non-condensing)8, Protection: IP20We produce these substitute S7-200,300,Profibus Products.>>>>Can be produced with your brand and model number.<<<<
