How to read PART 5 and PART 6
The contents described in this section are provided only for explaining how to read this manual. Thus, the actual description
may differ.
Indicates function symbols.
When character strings in brackets are added to the end of the function symbol for standard functions and function blocks, the
function symbol indicates multiple functions. For example, "DINT_TO_INT(_E)" means "DINT_TO_INT" and
"DINT_TO_INT_E".
Indicates the description format of the ladder diagram, FBD/LD language and ST (structured text) language.
In the square , either of the following symbol should be described.
• Standard function: Function symbol
• Standard function block: Instance name and function block symbol
The sign of return value of the standard function of FBD/LD is not displayed.
Indicates the description, type and data type of each argument.
Indicates the functions of each standard function or function block.
Indicates an error code which occurs at the execution and the error description when the standard function or the function
block has a specific operation error.
A device in which an error code is stored is described in the error code column. When an error code is stored in SD0, the error
flag SM0 turns on.
Function symbol
Description of symbol
Function symbol to which "(_E)" is added.
Indicates that the description format with EN/ENO can be used in the standard function and function block.

18.28
Converting DINT to INT
DINT_TO_INT(_E)
These functions convert DINT type data to INT type data.

Operation processing
• These functions convert the DINT type data input to (s) to INT type data and output from (d).
• A value input to (s) is the DINT type data value.
■
Operation result
1.
Function without EN/ENO
The following table lists the operation results.
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
*1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
