Byte Switching Suffixes

These suffixes are used to switch the bytes that compose data of type 16-bit Word, 32-bit DWord, or 32-bit Float.

The switching is applied after the device-level addressing option for byte Order is applied. For more information,

refer to Addressing Options.

Byte Switching Suffixes can be used with all memory types except Timers and Counters (T, C, and Z) and

Peripheral Inputs and Outputs (PI, PE, PQ, and PA). For information on the various types of switching that depend

on the suffix and data type of the item, refer to the table below.

Suffix 16-Bit Data Types (Word, Short, BCD)

32-Bit Data Types (DWord, Long, LBCD,

Float)

_X1 O1 O2 -> O2 O1 (byte switching) O1 O2 O3 O4 -> O4 O3 O2 O1 (byte switching)

_X2 O1 O2 -> O2 O1 (byte switching) O1 O2 O3 O4 -> O3 O4 O1 O2 (Word switching)

_X3 O1 O2 -> O2 O1 (byte switching) O1 O2 O3 O4 -> O2 O1 O4 O3 (Switching bytes

in the words)

Array Support

The <.array size> notation is appended to an address to specify an array (such as "MW0.10"). Boolean arrays

and string arrays are not supported.
