CONFIGURABLE PARAMETERS
Priority intervals This allows three levels of update rate to be entered. These rates are used in point
confi guration, to defi ne how often a value is read. In order to optimise the perform-
ance of the serial link, it is recommended that the slowest rate consistent with require-
ments be selected. The interval is entered in multiples of 1/8th second (0.125 seconds).
In some cases, two update rates can be defi ned. For example, when reading a Process
Value (PV) channel from a slave, it is possible to set the reading frequency of the PV to
the highest rate available , but other, less frequently changing, values (scale low/high
for example) can be read at a slower rate.
Store Diagnostics If enabled, diagnostics information is kept in non-volatile memory, and is thus retained
during power cycling.
Slave A picklist of slaves, initially called ‘Remote Device N’. When the device is detected, this
name changes to the detected Instrument’s Descriptor (if any) or a default tag. The
slave name can be edited in the ‘Descriptor’ entry fi eld below.
