Section 7: Table Functions

Table functions are used to perform the following functions:

Abbreviation	Function	Description	Page
ARRAY_MOVE	Array Move	Copy a specified number of data elements from a source	4-87
		array to a destination array.
SRCH_EQ	Search Equal	Search for all array values equal to a specified value.	4-91
SRCH_NE	Search Not Equal	Search for all array values not equal to a specified value.	4-91
SRCH_GT	Search Greater	Search for all array values greater than a specified value.	4-91
	Than
SRCH_GE	Search Greater	Search for all array values greater than or equal to a	4-91
	Than or Equal	specified value.
SRCH_LT	Search Less Than	Search for all array values less than a specified value.	4-91
SRCH_LE	Search Less Than	Search for all array values less than or equal to a	4-91
	or Equal	specified value.

The maximum length allowed for these functions is 32,767 bytes or words, or 262,136 bits (bits are available for ARRAY_MOVE only).

Table functions operate on these types of data:

Data Type	Description
INT	Signed integer.
DINT	Double precision signed integer.
BIT *	Bit data type.
BYTE	Byte data type.
WORD	Word data type.

*Only available for ARRAY_MOVE.

The default data type is signed integer. The data type can be changed after selecting the specific data table function. To compare data of other types or of two different types, first use the appropriate conversion function (described in section 8, “Conversion Functions”) to change the data to one of the data types listed above.
