Asynchronous Modbus Queue Handler for Controller Groups

The controllerGroupQueueAsyncmodbus method is an asynchronous method that handles the execution of the queue for a specific controller. It takes in three parameters: ctrlID which is the ID of the controller, ctrlData which contains information about the controller, and client which is the modbus client object used for communication.

First, the method clears the queue for the specified controller using Redis. It then connects to the modbus client using the connect coroutine method. If the controller is in the controllerStatus dictionary and its value is False, the method closes the modbus connection and returns.

Next, the method initializes the event timer using the initEventTimer method and sets the controllerStatus to True to indicate that the controller is running.

The method then enters a loop where it continuously monitors the queue for new items. If a new item is found, it is popped from the queue and processed using the handleQueueAsync method. If the modbus client is not connected, the method attempts to reconnect using the connect coroutine method.

The loop continues until the controllerStatus for the specified controller is set to False. If the timeDebug flag is set, the method prints out the loop time, the queue data, and the current datetime.
