Indirect addressing
using Index Registers
GETID(286) retrieves the data area address of the specified source variable
or address, outputs the data area code to D1 in 4-digit hexadecimal, and out-
puts the word address number to D2 in 4-digit hexadecimal.
The following table shows the variable type (data area) codes and corre-
sponding address ranges for the PLC's data areas.

Variables in function blocks are automatically allocated addresses by CX-Pro-
grammer Ver. 5.0 and later systems, unless the AT specification is used. For
example, if it is necessary to indirectly specify the extended parameter set-
tings of a Special Unit such as a Motion Control Unit and a variable is used at
the beginning of the extended parameter settings area, that variable's address
must be set. In this case, GETID(286) can be used to retrieve the variable's
data area address.
