Thank you very much, this was the problem.
We’ve created a Virt. Channel 32 – Discrete, which reads the device input 9.
And we’ve filled out each virtual channel per bit, with the GetBit(Val(9),n)
And this works! Tested with several open/closedWe didn’t enum text it yet. As i wanted to see the value.
Up to the next challenge, read out aprox 20x Current (0-20mA) sensor channels into Scada. (Thinking of raspberri/adruino via i2c and tranport via modbusTCP)
The current input value 0FFD -> 1111 1111 1101 (So IN2 is closed)
The Scada web interface shows IN1 closed, IN4 closed. Where did he get this from..?
If we physical change an input (closing it or opening it), nothing changes.Unfortunatly, i found out.. the table values are not changing.
So my first check (by remote) looked to give the right values but after more testing the channel values don’t change at al.I’ll come with more detail.
Ok formula is excepted,
But i am having troubles understanding the function GetBit(a,b)
What does GetBit do exact? how does this function ticks?
Is the assumption, a = position and b = value to compare?So if binvalue=1001 (binairy)
So GetBit(4,1) on binvalue, will result in GetBit being 1?
And GetBit (3,1) on binvalue, will result in GetBit being 0?In the given formula, we check if GetBit > 0.
And after this test we flip the boolean by 0:1?Sorry i have very very little C(++) experience 20 years ago, and lost that so i am trying to understand the function/way of thinking in this case.
Somehow the calculation engine fails on the Getbit formula.

sorry for the late reply, i will make the screen dumps today and will share them with you.
Unfortunatly i didn’t had time nor access to the test setup this Monday.OK, so:
the inputs are on Holding registers (4X), Start 9 Element count 1, 2 bytes ushortCommunicator log gives the decimal 4094 (so in1 is 0 closed)
Created in Administator, extra channel 19, in order of apperance :
19,
Active yes,
Digital IN1,
Calculated Discrete,
no object,
POC Device, (our name of the test device)
Signal 9, (get the data from channel 9?)
Formula used yes,
Formula : Getbit(1,1) (first bit in the row)
Averaging : No
Quantity : State
Format : D
Unit : Off – on
no else configured.For now it’s ok, i should invert the Getbit as 0 is on, 1 is resting state off.
That is for later concern.
Unfortunatly, i get the complete decimal 4094 -> 11111111110 or F FE from channel 9. Instead of the formula result..
What am i missing?
