Introduction

Conversion replaces the PL7 types and arrays by their Control Expert equivalent.

Types

The following table describes any correspondence and differences between PL7 and Control Expert types.

	PL7	Control Expert	Status
Type	BOOL	BOOL	Converted
	EBOOL	EBOOL	Converted
	WORD	INT	Modified (1)

	PL7	Control Expert	Status
Table	Boolean array (EBOOL) %Mi:n	ARRAY [0..n-1] OF EBOOL	Modified (1)
	Word array (WORD) %MWi:n	ARRAY [0..n-1] OF EBOOL	Modified (1)
	Array of double words (DWORD) %MDi:n	ARRAY [0..n-1] OF DINT	Modified (1)
	Floating point array (REAL) %MFi:n	ARRAY [0..n-1] OF REAL	Modified (1)
	Bytes array %MBi:n	STRING [n]	Modified (1)
