Resp_01_DPIDs[] 
This is an array which is used to store the DPID numbers for the send one 
response level of this service. The size of this array shall be at least as large as 
the maximum number of DPIDs allowed with a send one response $Level = $01 
request. This array shall be initialized at powerup to have all elements equal to 
$00.
 
This array shall contain at 
least 
max_No_of_01_DPIDs 
element 
Resp_01_Index 
This is a variable used to index into the Resp_01_DPIDs[] array when sending 
the one shot responses.
 
$00 to 
max_No_of_01_DPIDs - 1 
Resp_01_Num_To_Send 
This is a variable which is used to keep track of how many one shot responses 
still need to be sent. This variable shall be initialized to $00 at powerup.
 
$00 to 
max_No_of_01_DPIDs 
Num_Loops_For_01 
This is a counter which is used by the Process_AA_Msgs() function to determine 
when it is time to send a one shot response. This variable shall be initialized to 
$00 at powerup.
 
$00 to 
Max_01_Wait_Count

Variable/Meaning 
Values 
Max_01_Wait_Count
This is a counter used to compare against the 
Num_Loops_For_01 counter to determine when to send a one shot DPID instead 
of a periodic scheduled DPID. The value of this variable should be set based on 
the number of times the Process_AA_Msgs() function gets called in the 
background before a P2
C
time interval will have elapsed. The objective is to set 
this variable to a value which will ensure that a one shot DPID will be sent at a 
time interval less than P2
C
.
