GetBit (a,b)
a – channel data number from which you want to check the required bit
b – is the number of the bit to be checked from 0 to 64 considering that the database always has a double representation. But in fact, if you read one register, you can actually check only from 0 to 15 for example> 0 ? 0; 1 this entry you do the inversion if it is necessary
Not quite boolen, all variables RapidScada converts to double, this is a feature of the database implementation. However sometimes it is a hindrance 🙂 your perception is, Yes, a boolean.
Use C# help on MSDN
<Param name=”WriteMinPer” value=”60” descr=”Период записи минутных срезов, с” />
See settings of this file ScadaServerSvcConfig.xml but in this way you will increase the database in size
Sorry, all timer formulas still need Tiсks formula to work
public static long Ticks() { DateTime now = DateTime.Now; long time = now.Ticks/10000; return time; }Without this formula, all timers will give an error, and since the formula timers are different, but use the same calculation of the difference, the Ticks made a separate formula
Yes, the register should be read once and then on the basis of the input channel of this register to apply the formula GetBit in settlement channels. You really spend a lot of time on the same type of reading.
Then it turns out that you have everything right. 480 parameters this is clearly more than Modbus can allow with a single request. Try to separate the query groups so that the parameters you change are often in separate groups. That is to make a logical separation.
To set the settings property is an extraordinary interview after sending the command.
Also change the poll method to group, where possible
In this case, you do not need a hysteresis and just a timer with a delay off. TOF with time of 20 seconds.
int[] TofNum = new int[1]; long[] TofST = new long[1]; bool[] TofFlag = new bool[1]; public double Tof(double TofIn, double TofPT) { long ET = 0L; long tof_pt = Convert.ToInt64(TofPT); bool q = Val(CnlNum) > 0; bool tof_in = TofIn > 0; int res = Array.IndexOf(TofNum, CnlNum); if (res == -1) { res = TofNum.Length; Array.Resize(ref TofNum, res+1); Array.Resize(ref TofST, res+1); Array.Resize(ref TofFlag, res+1); TofNum[res] = CnlNum; } if (tof_in) { q = true; TofFlag[res] = true; TofST[res] = 0L; ET = 0L; } else { if (TofFlag[res]) { TofFlag[res] = false; TofST[res] = Ticks(); ET = 0L; } else { if (q) ET = Ticks() - TofST[res]; } if (ET >= tof_pt) q = false; } return Convert.ToDouble(q); }Add in the Formula of the Administrator
Configure the calculated channel formula – Tof(controlled channel, 20000)
C# can call functions of libraries written in C++ like. Not sure, but if I’m not mistaken, it is achieved using DllImport
You use a standard command, and it takes numeric values. Probably it is necessary to use a binary command and convert the string representation to hex with a formula ?Maybe that’s the reason.
