Modbus Scada Software Free Version But

Sketch i used is here:Modbus Organization Type: Software - SCADA Description: TOPKAPI software is an advanced industrial SCADA software with high processing power, reliability.And original sketch was copied here: #include Int temperaturePin = 2 //the analog pin the TMP36's Vout (sense) pin is connected toInt temperaturePin2 = 3 //the resolution is 10 mV / degree centigrade//(500 mV offset) to make negative temperatures an option//Arduino sketch example with 2 holding regs:/* Modbus setup example, the master must use the same COM parameters *//* 115200 bps, 8N1, two-device network */Float temperature = getVoltage(temperaturePin) //getting the voltage reading from the temperature sensorTemperature = (((temperature * 5) * 100)) //converting from 10 mv per degree wit 500 mV offset//to degrees ((volatge - 500mV) times 100)Float temperature2 = getVoltage(temperaturePin2) Temperature2 = (((temperature2 * 5) * 100)) // Serial.println(regs) //printing the result* getVoltage() - returns the voltage on the analog input defined byReturn (analogRead(pin) *. TOPKAPI is used by direct operators, engineers, and automation specialists designing and developing industrial applications.Yesterday i tested it with two temp sensors attached to Arduino UNO and after many hours got it finally working. SCADA and HMI software can easily.Found really nice SCADA/HMI software, few limitations on free version but if, with your help my friends i figure out this Modbus system it really is worth for buying.TopKapi SCADA Software: Software - SCADA: Modbus, Modbus TCP: TOPKAPI software is an advanced industrial SCADA software with high processing power, reliability, easy implementation.

Modbus Scada Software Manual For Modbus

Actually it is very simple to commucate between Arduino and Winlog via Modbus.IвЂ™m not saying that i fully understand this addressing system, but my guess is that the addresses you put to your Arduino sketch eg. SoвЂ¦ If here is somebody Modbus Arduino Expert, could you please give some links, hints, example sketches or anything what would clear this problem.Few days ago i finally found a solution. Obsolete2Ch:4h : Input register 4 (32 bit float).And yet again i spent allmost whole day at work to search information about Arduino Modbus configurations, addresses and everything but without any breakthrough which would cleared this thing in to my mind. Here is part of the Winlog manual for Modbus addressing and no matter how long i read and spell that text it doesnВґt make any sense with those Arduino MB_REG addressesвЂ¦30011 : Holding register 0011 (16 bit).Obsolete3h:10h:Bh : Holding register 11 (16 bit) with write function 10h instead of 6h.40004 : Input register 0004 (16 bit).Obsolete330011 : Holding register 0011 (32 bit float).Obsolete33:11 : Holding register 11 (32 bit float).21h:Bh : Holding register 11 (32 bit float).440004 : Input register 0004 (32 bit float).

XDAnd by the wayвЂ¦ IвЂ™m using different modbusSlave library what i used fisrt time. But if it works that way, iвЂ™m very happy. Led status is controlled from Winlog analog output value cause in modbusSlave library doesnвЂ™t support other function codes than 3,6 and 10. You get the point?I also managed to make a sketch with two LM35 temp sensors and one led. Equals Winlog addresses 30000, 30001, 30002 etc.

Modbus Scada Software How To Make Arduino

Is set to 1 so when you make devices to your Winlog project your device number must be same than your Arduino Slave id.Now because Arduino Modbus library uses ModBus functions 3,6 and 10 and Winlog supports only function 3 of those, you must use numeric gate for all your data what you want to read / write from / to Arduino.HereвЂ™s Arduino basic ModBus sketch: #include MB_REGS=6 /* dummy register. IвЂ™ve used COM Port8, Baud rate:115200, Stop Bits:1, Data Bits:8, Parity:None and Register Format: Standard mode.Read- and Write Timeout: 2000 ms and Query pause:50 ms.In Arduino sketch Slave id. And be sure that you have exactly same settings in Winlog options and Arduino sketch. Number of registers which was 256вЂ¦ WasnвЂ™t it?But if you or someone else need more help or examples from Arduino sketch or Winlog gate configuration, please feel free to askвЂ¦Sorry that i havenвЂ™t been visited here lately and tomorrow i have lots of time so i can make step by step instructions how to make Arduino and Winlog communicate with each other.But hereвЂ™s some вЂњfirst aidвЂќ to your problem.The protocol what you must use in your projects is ModBus RTU. With this вЂњnewвЂќ library i can have at least six registers, guess that there is possible to use max. So unless you donвЂ™t modify that library code i think that it is not possible to add more than two registers to your Arduino sketch.

So maybe easiest way is to set channel number, device number and slave id. In room temperature measurements it isnвЂ™t necessary to use 1 or even 5 second polling time, but thatвЂ™s my opinion.In gate configuration channel field you must use same channel where you configured ModBus RTU parameters and in device field your Arduino slave id. So sampling frequency depends on what kind of information you are reading or writing. If frequency is set to 1 Winlog polls your address 3:0 every secon, if set to 2 it polls that address every other second and so on. Set sample to Always and sampling frequency to value how often you want to read that value. Sample every 5 seconds */Regs = analogRead(A1) /* read input A1 */Regs = analogRead(A2) /* read input A2 */Regs = analogRead(A3) /* read input A3 */Regs = analogRead(A4) /* read input A4 */Regs = analogRead(A5) /* read input A5 */So if you want to read analog input 1 with Winlog, use address 30000 or 3:0 in your Winlog numeric gate.
