Temporary variable - VAR_TEMPdl-permalink__symbolPermalink

This function is an extension of the IEC 61131-3 standard.

You declare temporary variables locally between the keywords ‎VAR_TEMP‎ and ‎END_VAR‎.

‎VAR_TEMP‎ declarations are possible only in program blocks and function blocks.

CODESYS initializes temporary variables each time the block is called.

The application can access the temporary variables only in the implementation section of a program block or a function block.

Example

VAR_TEMP
		iVarTmp1 : INT; (*1st temporary variable *)
END_VAR
