The basic data types are given below.
This section describes the data format for bit string data.
 Bit String Data Format
Bit 0 is the least significant bit of a bit string variable. Bit values are expressed as 1 or 0.
Basic Data Types

BYTE
*1*2
*1. The BYTE data type cannot be used for an internal variable.
*2. If you use the BYTE data type for a global variable, you must define an exposed variable.
Standard data type byte#16#00 to
byte#16#FF
byte#2#0101010
byte#2#0101_1010
byte#16#5A
You can use the separator character “_”.
SAFEBYTE Safety data type
WORD
*3
*3. If you use the WORD data type for a global variable, you must define an exposed variable or use a constant.
Standard data type word#16#0000 to
word#16#FFFF
SAFEWORD
*4
*4. If you use the SAFEWORD, TIME, or SAFETIME data type for a global variable, you must set a constant.
