Create a server to receive flexsim model values and throw this data to me:
1 ===> It's the value that I wrote as an onCover event
0 ===> I do not know if it's because it refers to it using the modbus protocol
6 ===> I think he writes a simple record (16-bits)
-251 ===> I do not know if it refers to byte size
4 ===> It's the registration number
-256 ===> I do not know what it refers to either
My question is ... If I am correct or what does each of the data mean?
When you say it is throwing data at you, is it sending all of this in hex, or line by line? What are you using to capture the data?
Modbus protocol has a set of rules for what it does with the information given to it. You are actually missing several 0s which are important to reading the instructions sent to and from a PLC. Before you converted it, the hex format would read as follows
"\x00\x01\x00\x00\x00\x06\xff\x05\x00\x04\xff\x00"
You'll have to look up Modus protocol on what each chunk of bytes does.
I send him a video, to see how he works
And yes, I already found the modbus tables when it is big-endian and little-endian

I perform my tests, changing data and it's like detrining some relationships
