By the way, the answer to your question, @JOYE, is that FACTOR is how you deal with the decimal placement since you are converting the string representation to an integer. If the string looks like this: "123.45", then you would use a factor of 100 to result in an integer value of 12345. You can then display this integer number on the HMI screen and identify where to place the decimal. If you use the number in calculations, you would need to account for the fact that the number has been multiplied by 100 and deal with that properly.
Hi Kikis, the thing that bothers me about this device (I've looked at it in the past) is that it appears that it uses an intermediary server to do the connection. It doesn't appear to be a direct link because you "log in to your Talk2M account" using the "eCatcher client" to initiate the connection.
Perhaps this negative view is completely unfounded/unjustified and it is all perfectly ok, but I have a personal aversion to that sort of principle.
