5.5 STACK COMMAND
The STACK command is provided to allow the technician to gauge the health of the RX4A
microprocessor and its code by displaying the maximum usage of the program stack. The
display is a peak value of the stack usage since the RX4A was powered up. The
command can be invoked as shown in the example below:
RX4A::>STACK
Stack usage/size = 312/1024
Percentage Used = 30%
RX4A::>_
This command would typically only be used when requested by an Austdac software
engineer.
5.6 SILBUS MAP COMMAND
The SILBUS map command allows the operator to obtain a snapshot of the SILBUS
network to which the receiver is connected. The map shows all of the SILBUS channels
available on the network. The map consists of a table with a heading of groups below
which is displayed the channels using ones and zeros. Each group is shown vertically with
1 at the top and 8 at the bottom. A one indicates an ON channel and a zero indicates an
OFF channel. An example of an SBMAP is shown below with channels A4, P7 and P8 on
or active:
RX4A::>SBMAP
ABCDEFGHIJKLMNOP
0000000000000000
0000000000000000
0000000000000000
1000000000000000
0000000000000000
0000000000000000
0000000000000001
0000000000000001
rX4A::>_
The SBMAP command is particularly useful when used with the repeat command as this
will display a continuously updated table.
5.7 SILBUS STATUS COMMAND
The SILBUS status command displays the number of SILBUS channels available on the
connected SILBUS network, a SILBUS synchronisation pulse count and a SILBUS error
count. This command is used to determine if the connected SILBUS network is functioning
correctly and how many channels are available. The error count should typically be zero
while the sync count should be incrementing. Once again the use of the repeat command
will provide a dynamic updating display. An example of the SBSTAT command follows:
