3: Typical Sequence of Operations
DC 900-1564A 29
• The application writes a DLI_PROT_SAFE_STORE_ACK command that confirms
receipt. Some restrictions might apply due to the specific configuration of the ICP
link.
3.7 Sending an SLC Block
If an ICP link is configured for SLC envelope service (default), then after the application
attaches the ICP link with Master access mode and binds the link, it can send SLC blocks
to the SLC network via the ICP link. The application is responsible for conforming to
the SLC protocol restrictions on block content. To write a block, the application must
perform the actions listed below.
• The application writes a DLI_PROT_SEND_TRANS_DATA command. There is no
acknowledgment; however, the application detects transmission errors by reading
a
DLI_PROT_SEND_TRANS_DATA response with a status that indicates the error.
3.8 Receiving an SLC Block
If an ICP link is configured for SLC envelope service (default), then after the application
attaches the ICP link with Master access mode and binds the link, it can receive SLC
blocks from the SLC network via the ICP link. To read a block, the application must
perform the actions listed below.
• The application reads a DLI_PROT_SEND_TRANS_DATA response with a status that
indicates no error. No acknowledgment is required.
3.9 Exerting Operator Control
If an ICP link is configured for low-level or high-level SLC network service, then after
the application attaches the ICP link with either Master or Control access mode and
binds the link, it can exert operator control over the link. To exert operator control, the
application must perform the actions listed below.
