4.4 SC_C_DISCONNECT_UNIT

Purpose

Notifies the remote controller that a unit has lost his connection with the CCU (i.e. the unit is

disconnected from the ACN-trunk or MOST-trunk). This notification informs the remote

controller that the unit is no longer available.

Notify structure with this update

The update comes along with the same structure as defined in section 4.3.

4.5 SC_C_CONNECT_SLAVE_CCU

Purpose

Notifies the remote controller that a slave-CCU has connected to the master-CCU.

Notify structure with this update

The update comes with the following structure:

typedef struct

{

BYTE bySlaveId;

WORD wFillLevel;

SC_T_UNIT_DATA tConnectedUnits[SC_C_CLUSTER_MAX];

} SC_T_CCU_CONNECT;

where:

bySlaveId The identification number of the slave-CCU involved.

wFillLevel The number of units present in the tConnectedUnits array. Only

this amount of array elements is transmitted.

tConnectedUnits A list of units that are connected to the slave in question. This

means that all units reported in the list are also connected.

Each list element is defined as a SC_T_UNIT_DATA structure

which is defined in section 3.6.

Note: Although the list is defined with SC_C_CLUSTER_MAX

elements, only the maximum number of units possible

for one slave will be transmitted.

Currently the wFillLevel parameter will always be zero. Due to the nature of the units and the

control flow used with the CCU (slave and master), each unit will connect itself using the

notification SC_C_CONNECT_UNIT. Therefore no units are reported in this list. Future

extension in the software could build a list of units connected to a slave. That list should then

be reported in the tConnectedUnits list.

4.6 SC_C_DISCONNECT_SLAVE_CCU

Purpose

Notifies the remote controller that the master-CCU has lost connection to one of his slave-

CCU’s. Along with this notification a list of all units connected to that slave is send. This

notification tells the remote controller that the listed units are no longer available.

Notify structure with this update

The update comes with the following structure:

typedef struct

{

BYTE bySlaveId;

WORD wFillLevel;

SC_T_UNIT_DATA tDisconnectedUnits[SC_C_CLUSTER_MAX];

} SC_T_CCU_DISCONNECT;

where:

bySlaveId The identification number of the slave-CCU involved.

wFillLevel The number of units present in the tDisconnectedUnits array.
