As soon as the deployment action is executed and the data transmission has been started by the client, the initialization of the tags begins. Depending on the PLC type, the tags in a request are initialized with a single service packet or with multiple service packets. For a request with a single service packet, one tag after the other is initialized. For requests with multiple service packets, the tags are initialized in batches. As soon as the request is complete and a batch of tags has been initialized, the exclusive reading of these tags begins. Tags not initialized within the time limit of 1 second (30 seconds for first connection attempt) are retried after the limit exceeds. If the second initialization also fails, the quality status is set to Bad. The result of the initialization for each tag is shown in the columns of the connector. The status is displayed in IIH Essentials and forwarded by the Databus Gateway to the Databus. The following diagram shows the process:
