SHARE AND SHARE-NET EXAMPLE
To demonstrate the use of the SHARE and SHARE-NET functions, consider the BACnet
network detailed in Figure 65.
FIGURE 65: EXAMPLE BACNET NETWORK
Notes on Figure 65...
1 Implementing the SHARE function in Device #1000 will result in SMART-Space
Controllers #1201 and #1202 receiving updates of the shared object. None of
the other SMART-Space Controllers will receive the shared object updates
because the SHARE function does not broadcast over B/IP or B/Ethernet
networks.
2 The following line of Control-BASIC is written in a program in device number
1203 or 1000:
10 A = SHARE-NET( 201 , OAT , 0.5 )
If the OAT object changes by 0.5, or more, the OAT object will only be
broadcast to the SMART-Space Controllers on MS/TP network number 201,
which will in turn will only be received by device #2001. None of the other
SMART-Space Controllers will receive updates of the OAT object.
