Standard battery life
The relationship between the Update time of a Field Wireless Device and the battery life in a
standard specification environment is shown below.
The battery life of an IO device is constant irrespective of the network form or the route connec-
tion. However, the battery life of a routing device varies greatly according to the route connection.
The larger the number of directly connected devices on the downstream side, the shorter the bat-
tery life.
In addition, the battery life varies greatly with temperature; the battery life may be shorter than the
service life shown below.
