Function
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 outputs the word address number to D2 in 4-digit
hexadecimal.
• Variable type (data area)
CIO Area
Work Area
Holding Area
DM Area
EM Area (Specific bank)
Hint
Variables in function blocks are automatically allocated addresses by CX-Programmer Ver. 5.0 and later
systems, unless the AT specification is used. For example, if it is necessary to indirectly specify the
extended parameter settings 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.

Indirect
specifica-
tion
The starting address of the extended parameter settings
area is specified by the FINS command variable type
(data area) code and word address. In this example,
#0082 specifies the DM Area and &100 specifies a
100-word offset from the beginning of the area.
