7.2 Memory Allocation of XW, YW and MW
Memory for XW, YW and MW registers for particular model is allocated by software at the time of I/O allocation. The
number of XW, YW and MW for the particular model is as per the table given below:

The allocation is sequential. If any particular model does not have XW / YW / MW defined then the memory is not
allocated in the array for that model. This array is sequentially mapped to Modbus registers.
Consider the example that user has configured the models as below:
Slot 0 :
GPU288
:
XW : 1,
YW : 1,
MW : 60
Slot 1 :
GDR288
:
XW : 1,
YW : 1,
MW : 0
Slot 2 :
GRO216
:
XW : 0,
YW : 1,
MW : 0
Slot 3 :
GDD288N
:
XW : 1,
YW : 1,
MW : 0
Slot 4 :
GDI216
:
XW : 1,
YW : 0,
MW : 0
Slot 5 :
GAD208L
:
XW : 8,
YW : 0,
MW : 50
