Alarm Handling
The operator panel network is a client/server network. Servers provide data, e.g.
alarm signals, to clients. A large number of different signals influence the communi-
cation time between operator panels and controllers in the network, which means
that the number of these signals should be limited. For further information, see the
chapter Efficient Communication. The number of alarm signals the network receives
must not exceed the number the server can handle in the complete network. One
server can handle up to 300 alarms, depending on the application and operator pan-
el. This means that the network must not contain more than a total of 300 alarms.
Index in Network Client
Index addressing, which makes it possible to select from which register an object is
to collect the shown value, see the chapter Index Addressing, cannot be used in oper-
ator panels functioning as BDTP clients. BDTP clients only use the BDTP servers
index register. If, however, an operator panel which is a BDTP client also has a local
controller, normal handling of index addressing is applicable in accordance with the
chapter Index Addressing.
18.7 Obtaining the MAC Address during Runtime
The unique hardware number of the operator panel, the MAC (Media Access Con-
trol) address, can be obtained during runtime by using a macro with the IPCONFIG
command and the /ALL argument. Not available for E1012 and E1022.
The IP configuration including the MAC address will then be displayed in a
Windows CE Console.
Please see chapter Macros for further information about macros.
