system.tag.writeAsync(tagPaths, values, callback)
List tagPaths - A List of Tag paths to write to. If no property is specified in a Tag path, the Value property is assumed.
List values - The values to write to the specified paths.
PyFunction callback - A Python callback function to process the write results. The function definition must provide a single argument, which will hold a List of quality codes when the callback function is invoked. The quality codes will hold the result of the write operation for that Tag.
