I am using a PC on remote location which has a java code for sending data to TW platform in cloud. I have this remote PC connected to a PLC which fetches the data, also some other DB is connected from which data is fetched. Data fetching frequency is one sec. I would like to know what should be the internet speed for healthy communication. Just for example I have 100 tags from PLC and 8 tables in DB to which this code monitors.
