Performs a write to a tag, synchronously. This means that you know at the end of this function whether or not the write succeeded or not. A write that fails or times out will throw an error. However, this function cannot be called from the event dispatch thread, which means that it cannot be called directly from a GUI event like a button press, without wrapping it in a system.util.invokeAsynchronous. You can call this from project event scripts like timer scripts.
This scripting function has no Client Permission restrictions.
system.tag.writeSynchronous(tagPath, value [, timeout])
String tagPath - The path of the tag to write to.
Object value - The value to write.
int timeout - How long to wait in milliseconds before timing out pending writes. The default is 45000 milliseconds. [optional]
