2. Configuring an I/O Master
Max Packet Size and Min Packet Size
Setting
Description
l
At a packet size of
Max = 2 Min = 2
, the maximum available count
would be 6Hz.
l
At a packet size of
Max = 9 Min = 9
, the maximum available count
would be 3Hz.
l
The pulse state must last for a 50% duty-cycle (that is, a 3Hz pulse needs
to last at least 166.6ms and a 6Hz pulse needs to last at least 83.3ms).
This table provides the available packet sizes in bytes for an I/O System by chartering the
Maximum Packet Size
and
Minimum Packet Size
setting when the
RF Data Rate
is set to
3
.
