1.12.2 Setting the Mapping Parameters
To set mapping parameters
1 Enable the Use BP Map Table parameter with a value of Y as follows:
Use BP Map Table : Y #Use BP mapping (Y=Use maps, N=Don't use maps
(default))
2 Setup the mapping for your application through the [FL-NET BACKPLANE
MAPPING] section of the configuration file.
Where each parameter is defined as follows:
Parameter Description
Node Node number
A1 Network Start Start word offset in the node area (within the network common
memory) to be mapped into the virtual backplane map. This is not the
absolute offset within the common memory. For example, if the node
top address is 200 (size of 150 words), in order to remap the last 50
words of that node then enter a A1 Network Start value of 100 (not
300).
A1 Network Size Total number of words (starting from A1 Network Start offset) to be
mapped into the virtual backplane map.
A1 Network Backplane
Start Start absolute word offset in the virtual backplane map where the
mapped A1 data will be copied to.
A2 Network Start Start word offset in the node area (within the network common
memory) to be mapped into the virtual backplane map. This is not the
absolute offset within the common memory. For example, if the node
top address is 200 (size of 150 words), in order to remap the last 50
words of that node then enter a A2 Network Start value of 100 (not
300).
A2 Network Size Total number of words (starting from A2 Network Start offset) to be
mapped into the virtual backplane map.
A2 Network Backplane
Start Start absolute word offset in the virtual backplane map where the
mapped A2 data will be copied to.
3 Setup the portion of the virtual backplane map to be transferred to the
processor.
BP Area 1 Top : 0 #0...511 top address for area 1
BP Area 1 Size : 200 #0...512 area 1 data size in words
BP Area 2 Top : 0 #0...8191 top address for area 2
BP Area 2 Size : 200 #0...8192 area 2 data size in words
The following example shows how to use the map feature by configuring the
module parameters.
