ParticipantSomething is not working to display the number in binary form. It shows
!!!
on the graph, in the table---

ParticipantFormat Channel – String
Data Type = ASCIIpublic string BitsView(double number)
{
byte[] data = BitConverter.GetBytes(Convert.ToUInt16(number));
uint N = BitConverter.ToUInt16(data, 0);
string bits = Convert.ToString(N, 2);
return bits;
}Make a calculation channel with the specified parameters. Use the specified formula. Displaying a string in the channel, but only for a byte. In order for the whole number to be displayed correctly, the formula needs to be refined.

Participant00000010 is a binary display of bits of a number, I don’t even know if there is support for such a display in the system. I wrote some kind of formula for this and displayed it as a string

ParticipantSet the HEX format in the channel, perhaps this will be enough for you.
There is a choice there
Hexadecimal
Hexadecimal 2 digits
Hexadecimal 4 digits
Hexadecimal 8 digits-

Participant00000010 in the bit representation is the number 2 in the decimal representation. Do you need to see the number in some other format?

ParticipantGetAnyBits(Val(1080), 3, 7)
Val(XXX) – Where is the XXX number of your channel00000111 is the number 7 in the bit representation
When you need to select 3 bits in a value, you need to make a logical AND with the bits you need, and depending on which bits from the beginning you want to compare, you need to shift the bits you need so that they turn out to be starting from the zero bit00001111 is the number 15, which will correspond to four consecutive bits
00000011 is the number 3, which will correspond to two consecutive bits
01010110 – Your certain number for checking 3 bits. You need to shift this representation to position 0 (n = 2) 00010101 and make AND with the number 7 (00000111)

Participant00111000
The 0th bit is on the right. You need to shift by 3
GetAnyBits(Val(XXX), 3, 7) like this

Participantpublic double GetAnyBits(double val, int n, int mask = 1)
{
ulong ulVal = (ulong)val;
return (ulVal >> n) & (ulong)mask;
}I haven’t checked, but the mask should work by default. The mask is 1. Which fully corresponds to the getBit formula
You can set 3, 7, and so on.
n is the offsetmanjey73
Participantpublic double GetThreeBit(double val, int n)
{
ulong ulVal = (ulong)val;
return (ulVal >> n) & 7ul;
}Here the number 7 (00000111) is used as a mask
manjey73
ParticipantIf you always need to pull out 2 bits each, then you can make one formula, just like getBit. If your pairs may differ, then you will need to make a formula and install it with your hands. Modify getBit into a different formula
public double GetTwoBit(double val, int n)
{
ulong ulVal = (ulong)val;
return (ulVal >> n) & 3ul;
}Here 3ul is the number 3 (00000011) and by shifting the bits by the right amount you make a logical one with two bits at once, and not one as in getBit. You can look at how much you need to shift in a calculator or even on a piece of paper.

ParticipantPerhaps the username and password should still appear in the request, even if they are empty

ParticipantAnother option is to use the Auto-control Module and calculation channels for the values. But it seems to be superfluous here if Modbus is used
manjey73
ParticipantHmm, sending different values from different buttons but to the same channel is a rare task. I remember there was such a problem, just related to the fact that it is impossible to specify a value when selecting “Send command immediately”
You need to make several calculation channels that will have their own formulas with different values to specify these channels in the buttons.
The Modbus device to which you are sending commands?
Add additional commands to the template that will lead to the same register and link them to the created channels.manjey73
ParticipantOnce you have indicated that the channel type is hex, write in the output formula of channel 111e and specify “Send command immediately” on the mnemonic and check.
If you need to send different values using different buttons, then you probably need to write a formula and use an enumeration.
