Respected Steve Sir, I have a doubt regarding the data output from the Node red Config buffer parser. I am using SMC pressure Sensor IO link and I configure it on the PORT 1 (There are 04 ports on IO Link Master starting from PORT 01 and goes to PORT 04) and I gave 2 bytes of process data as desc…

Firstly, some actual data and the value you expect it to represent would be helpful. Use the Copy Value button that appears when you hover over an item in the debug panel. And when pasting the data to your reply, wrap it in triple ``` backticks to preserve formatting. Please provide the data comi…

Respected Steve Sir, Are you able to import my flow ? I think I forgot backticks in previous response: I am expecting the pressure value to be "0.58 Mpas". (Out1-On) (Out2-On) (diag- Normal) Function code in the "Convert array to Parser" I converted the output of OPC in the array format as I wa…

[image] RakeshKamkilal: I am attaching the whole flow again Like last time, you have only exported 1 node. To export a flow, you need to select all nodes you want in the export. PS, dont bother exporting your FULL flow as I dont have your OPC data source (or OPC nodes installed) - instead, …

Ok Steve Sir noted. Did you get the data that is required to understand my problem or where I am making mistake ? I am giving offset = 10 as the data is on byte 10, using Int16(le) as the data from SMC vendor is coming in Little endian. 10.0 Out1 10.1 Out2 10.2 Diag 10.3 to 11.7 Process data …

Yes sir I was talking to you about the end result in unit of "Mpa" IO link is digital so i will get digital or binary values. Did you also see in parser in "Scaling" I used ">>>3" to shift to right just by three bits to remove the unwanted data. Then I multiplied the output of parser with 0.000250 …

[image] RakeshKamkilal: It is just that when I changed the port1 to port 3 Its not working so there is something that I am missing in offset or fundamentals wrong. So when you change to another port on IOLink, the data is in a different position. You had an offset of 10. Which means you were …

Respected Steve Sir, I don't understand it. Ok I got the point that when I convert it to array each element is of 16 bit rather then 8 bit but then how do i get correct response. ? After converting it to buffer as you said for the same pressure reading I am getting different values. What data ty…

Your flow: [image] [image] Steve-Mcl: instead, you could simulate the OPC data by capturing it (Debug->copy value) and adding to your flow using an inject + function node.

When you provide sample data PLEASE provide what value you expect these to be. [image]

It is very unlikely the data in those 13 bits are formatted for the the unit MPa - io-link data is often binary and requires conversion. Do you have this information?
