4.2 Scanned Function Codes
The interface card provides network access to the specified list of function codes. These function codes
are constantly being read and/or written (as applicable), and their current values are therefore mirrored
in the
interface card’s internal memory. Only those function codes selected in the
Manage Device
Parameters configuration windows in the Configuration Studio (refer to section 6.8) will represent
meaningful values.
The principle disadvantage of scanned function codes is that write data checking is not available. This
means that when the value of a scanned function code is modified via a network protocol, the interface
card itself is not able to determine if the new value will be accepted by the inverter (the value may be
out-of-range, or the inverter may be in a state in which it will not accept new values being written via
communications, etc.) For example, if a write is performed to a scanned command function code with a
data value that is out-of-range, the interface card will not generate a corresponding error. However, if
end-to-end confirmation of such data writes is required, then the function code can be read over the
network at a later time to confirm that the
written value “took hold” in the inverter.
Accesses to any function code
(?00…?99, where “?” is any valid function code group letter from Table
14) will always be successful. Even if an inverter function code corresponding to a given register does
not exist in the
Manage Device Parameters , the interface card still maintains a placeholder location in
