In this case we use a WTB4F and a SIG200 and would like to have only the current receiver level from the process data.
The process data of the WTB4F looks like this.
/msdyn_blobfile/$value)
The IO-Link data (process data) from port 1 of the SIG200 starts from Byte 8 in the input assembly.
/msdyn_blobfile/$value)
In the PLC you will find the input assembly like this. All variables are defined as data type SINT
/msdyn_blobfile/$value)
We would like to have the current receiving level without a negative sign in front and we would like to have it in one variable.
So in the first step we define a variable of the data type INT and give it a name, in this case I name it “Test_INT”
/msdyn_blobfile/$value)
In the next step we have to move Byte 8 and 9 into this Test_INT variable without the switching bits.
For this we use the function BTD (Bit Field Distribute) from the Rockwell Studio 500.
/msdyn_blobfile/$value)
Source = the byte (Tag) which contains the bits to move, in our case it is one time SIG200:I.Data[8] and SIG200:I.Data[9].
Source Bit = Lowest Bit number from where to start the move From Data[8] it starts from 2 and from Data[9] it stars from 0
Dest = Is the destination Byte (Tag) where to move the bits. In our case it is Test_INT
Dest Bit = The number of the Bit to which the data should be move. Data[8] should move to Bit 0 of Test_INT and Data[9] should move to Bit 6 of Test_INT.
Length = number of Bits to move. From Data[8] we move 6 Bits and from Data[9] we move 8 Bits.
In the program it looks like this.
/msdyn_blobfile/$value)
At the End you have the current receiving level in one variable without negative sign in front
