ControLink86 Realtime Networking Software
Example:
3.6.1.2STATION COMMAND/RESPONSE PROCESSING
The following station command/responses are used for internal servicing. If the station SAP (0) receives a
null (0) destination SAP value then it responds accordingly. These messages are used for duplicate
address checking which is done in hardware/software by the COM2002x chip. These functions are
supported to allow for non-COM2002x devices to check for duplicate addresses.
Note these services are automatically performed by the LLC software and are invisible to the system.
3.6.1.3DISABLE STATION/NODE
The disable station request terminates all SAPs and shuts down the station and node hardware. The
node is then removed from the network. The following occurs when a Disable Request is sent:
Example:
3.6.1.4STATION/NODE STATUS
Processing this service is based on the value of the llssap:
Example:
…
/* startup the station, 0 is station SAP */
event = ENABLE_WITH_DUP_ADDR_CHECK;
/* initialize LLC driver */
status = llc1_request(0,0,event,&lsap[0]);
/* check to see if the initialization is completed */
if status = =E_UP
else if (status ==E-DOWN)
else
RECEIVE_NULL_DSAP_XID_C
RECEIVE_NULL_DSAP_XID_R_CNT_0
RECEIVE_NULL_DSAP_XID_R_CNT_1
RECEIVE_NULL_DSAP_TEST_C
1. Host issues a DISABLE_REQUEST command to it’s stations Logical Link Layer.
2. Global variable: llc1_station_state is set to DOWN (which prevents any request processing) and
/* bring down the station */
event = DISABLE_REQUEST;
status = llc1_request(0,0,event,&lsap[0]);
•
•
…
/* read status of sap */
printf(“Station/LSAP Status = “);
event = REPORT_STATUS;
status = llc1_request(1,0,event,&lsap[i]);
the Network Hardware (transmitter and receiver) is disabled.
if llssap = 0 Then the station state is returned
if llssap > 0 Then the state of a SAP of GSAP is returned
{
/* ok */
}
{
/* error initializing */
}
{
/* invalid response */
}
