(0x66) Get Extended Module Information
When querying SeaI/O modules, perform a standard Get Config (0x45) request. If
the Get Config response returns zero (00) for the model number, the module being
queried is outside the original SeaI/O 4xx series. Use the Get Extended Module
Information request to retrieve the (full two-byte) model number for SeaI/O
modules outside the original SeaI/O 4xx series.
This transaction shows that the SeaI/O module queried is a SeaI/O-520 (e.g., Hex
0208 = Decimal 520). The additional 14 bytes of data has been reserved for future
use. There are no exception codes possible with this transaction.
Request Response
Field Name (Hex) Field Name (Hex)
Function 66 Function 66
Model (upper byte) 02
Model (lower byte) 08
RESERVED [14 bytes]
NOTE:
The (0x45) Get Config request should still be used to retrieve the
bridge unit, baud rate, and parity of all SeaI/O modules.
