Processes commonly need to read properties that other processes write. Maps contain points, which work like variables that store only the latest value written to them. In other words, point value maps are repositories of information that any process can read and write at run time.
In the example of reading the current operating state of a machine, processes do not require knowledge of every change in operating state that occurs, but rather, only the current state. Point value maps are designed for this use case, where the device software must store a value in memory that readers and writers can access with no flow control.
The palette for the Point Value Map Library can be found under Addons.
Below is a simple example showig how to write and then read points from a map.
