3: FMP DLI Functions
DC 900-1339H 63
Caution
The 16-bit header fields are not byte-swapped by the FMP soft-
ware. The client application must perform any necessary swap-
ping. Additionally, packed data headers might not start on word
boundaries. The packed data is in most significant byte (MSB) first
order in the data area.
3.5.2 Error, Confirmation, and Acknowledgment Responses
Table 3–8 lists the possible FMP error, confirmation, and acknowledgment response
codes returned in the
dlRead pOptArgs.usProtCommand field. All of the responses, as well
as the
DLI_PROT_RESP_ERROR error report, can return an error code in the dlRead
pOptArgs.iICPStatus field to indicate failure. Section 3.4.3 on page 57 gives more
information about the data acknowledgment response (
DLI_PROT_RESP_LOCAL_ACK).
3.5.3 Reports in Response to dlWrite Information Requests
After issuing a dlWrite information request (Section 3.4.2 on page 53), a dlRead request
must be issued to receive the report information. The reports are listed in Table 3–8 on
page 61.
