*Data associated with these addresses are only read from the device at the start of a communications
session. Once read, the values will not be refreshed until the server has been restarted or the "Reset" tag
has been invoked. To invoke a reset, a non-zero value must be written to the Reset tag. Once the Reset tag
has been invoked the driver will reinitialize all startup data from the device.
Alarm Setpoints
Data values for Alarm Setpoints that are undefined in the device will be returned as +INF. Data values can
only be written to Alarm Setpoints that are defined in the device. Write operations to undefined Alarm
Setpoints will return an error. Write operations are available only for users logged in at the Administrator
level and will return an error otherwise. Alarm setpoint values are read one channel at a time. For devices
with a large number of channels, increasing the scan rate of ASP items and/or reducing the number of active
ASP items will increase the read performance of the PV and alarm data.
