Box
Setting
Interscan Delay
Sets the scanner time delay between consecutive I/O scans on the network. For this
example, we recommend using the default setting of 10 milliseconds.
TIP: When numerous drives are on the network and the drives are faulting on a Comm
Loss, increasing this value may help.
Foreground…
Sets the ratio of foreground to background polls. For this example, we recommend using
the default setting of 2.
Slot
Sets the slot location in which the scanner is installed. For this example, Slot 3 is
selected.
TIP
The Automap on Add box is checked by default and allows RSNetWorx
for DeviceNet software to automatically map the drive I/O into the
scanner in the next available registers. The mapping is based on the
minimum I/O requirements (8 bytes for input and 8 bytes for output)
that the scanner obtains from the drive EDS file.
