Setting the Remote I/O Allocation Method
Set the remote I/O allocation method and click on “Next.” The following table
describes the two methods.
Setting
Allocation method
Allocate each node by channel
Slaves are always allocated memory starting with the “Low” byte in the word. Even
Slaves that require just one byte of I/O memory will occupy one word.
Example:
Node-address order
Unused memory
#0
High
Low
15 to 8
7 to 0
#1
#3
#4
#6
Allocate so that total number of
occupied words are minimized
When there are Slaves that require just one byte of I/O memory, they are allocated
“Low” and “High” bytes so that as much unused memory is occupied as possible.
Example:
Node-address order
Unused memory
#0
High
Low
15 to 8
7 to 0
#1
#4
#3
#6
