4.4.7  Map Descriptor Example4 – Gas values for the current (most recent) slot sample. 

This example illustrates a  map descriptors used to store the data from the most recent slot sample. The map descriptor stores the following 
information :- 

5. Slot 

Number 

6.  Up to 16 gas values (The gas name is not provided) The position in the array is based on the Gas Number.  

For example. A slot may sample two gasses. The first is Gas #4 and the second may be Gas #2, The driver stores the value of Gas#4 in 
array location 4 and stores the value of Gas#2 at array location 2. 

The following additional information may also be stored if the DA_Bit_Name & DA_Byte_Name parameters are specified. 
7.  A bit indicating the number of the slot 
8.  The Alarm/Warning States for each gas 
 

Map_blocks 
Map_block_Name, Data_Array_Name, Data_Array_Offset, Function, node_name, protocol, timeout, atmi_data   , da_bit_name, da_byte_name 
Current_Port_MD, DA_CURR_SLOT, 0                             , passive   , ACM1      , ATMI    ,120.0s  , current-slot, DA_SLOT  , DA_SLOT_ALA

 

 

The current slot 
number and up to 16 
gas values are stored 
in this data array. 
 
The 1

st

 element 

stored is the slot 
number.  The next 
16 values stored are 
the gas values 
(multiplied by 100). 
The location is 
based on the Gas 
Number and not the 
row number. 
 

This keyword tells 
the driver to use this 
map descriptor to 
store the current 
slot’s sample data..

 

If x is the number of the current 
slot (slot most recently 
sampled) then the data array 
position corresponding to x is 
set to 1 and all other elements 
are set to zero. 
 
E.g. If Slot 1 is the current slot 
then the  2

nd

 element of the 

array (index=1) is set non-zero.
 
The array can be any data 
format.  
If the DA_Bit_Name parameter 
is omitted then this data is not 
stored.

Alarm / Warning Status for each gas is 
indicated in this array. 
 
If gas x is in alarm then x is used as the 
index into the array. E.g. If Gas #1 is in 
alarm then the 2

nd

 element of the array 

(index=1) is set non-zero. 
 
The value of each element indicates 
alarm/warning. If the Value is 1 then the 
gas in alarm. If the value is two then the 
gas is at a warning level. 
 
The array format should be capable of 
storing a value. If a Bit/Packed_Bit format 
is used then you will not be able to 
distinguish between an alarm/warning. 
 
If the DA_Byte_Name parameter is 
omitted then this data is not stored.
