libplctag / libplctag4j Goto Github PK

Modify the build configuration so that the repo can be checked out and used as is when building an Android app. Alternatively, build both a fat JAR and a "skinny" JAR and see if Android can use the skinny version.

This is from @GitHubDragonFly's comments in core library issue 189.

Another thing, related to your Tag.java, is that Android doesn't seem to like this line:

NativeLibrary.getInstance(Tag.JNA_LIBRARY_NAME)

It seems to be causing this error: "The SecurityManager implementation on this platform is broken; you must explicitly provide the class to register". I thought it was related to ASan libraries but it looks like I was wrong.

The build instructions in the README are incorrect. The command line for building the JAR files should be:

gradle -b build-jar.gradle clean shadowJar

an example of how you can read or write a UDT tag with libplctag4j, thanks

To continuously display the value of some tags, I use the following instruction:

tag2.Read(TIMEOUT)
tag3.Read(TIMEOUT)
tag4.Read(TIMEOUT

val2 = tag2.GetInt32(0)

LabelTAG_INT.Text = val2

val3 = tag3.GetFloat32(0)
LabelTAG_REAL.Text = NumberFormat(val3,0,1)

val4 = tag4.GetString(0)
LabelTAG_STRING.Text = val4
instructions that repeat within a loop, it works fine, but is this the correct way?
make constant read calls, affect the performance of the computer?

the language is B4X, and it is a wrapper for this platform, but it is still in testing. Thank you

I use the libplctrag4j library. I would like to know the correct way to write on a tag of type string, because sometimes the result is not the desired one

is this correct?
tag4.SetString(0,"value")
tag4.Write(TIMEOUT)
