Maybe it will sound like rookie question, but reading WM-BUS specs I did't found any info about the min. access time to the WM-BUS device. If I explain myself, I've two WM-BUS devices let say one is master and one slave and I need to update data from slave very often. So the question is what is the minimum amount of time between two reads.
I am planing to use the device in the bidirectional mode (S2 or T2).
Thanks for the answer.
I know WM-BUS it was designed to reduce the power consumption, but I don't have this problem and I am m
sorry for the delayed answer, I hope it is still valuable. The problem is not only power consumption, but also permitted duty cycle according to EN300 220 and EN 13757-4, which is 0.1% for S and T meters in a small network. This leads to a maximum update rate of about 12 seconds, depending on your frame size.
