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

array to a destination array. 4-87

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

Than Search for all array values greater than a specified value. 4-91

SRCH_GE Search Greater

Than or Equal Search for all array values greater than or equal to a

specified value. 4-91

SRCH_LT Search Less Than Search for all array values less than a specified value. 4-91

SRCH_LE Search Less Than

or Equal Search for all array values less than or equal to a

specified value. 4-91

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.
