Iec005 - Return Type has to be IEC compatible

Severity: Error

IEC methods/functions have to return types that are compatible with IEC. IEC methods/functions that can have return values are methods that either:

• have the attribute [User]
• have the attribute [Execution], are called __Process and are in a class with the attribute [Function]
• have the attribute [Function] and are in a class with the attribute [FunctionContainer]

Explicitly allowed types are

CSharp basic types:

• bool
• sbyte
• short
• int
• long
• byte
• ushort
• uint
• ulong
• float
• double

.Net basic types:

• Boolean
• SByte
• Int16
• Int32
• Int64
• Byte
• UInt16
• UInt32
• UInt64
• Single
• Double

IEC types:

• enums attributed with [Enumeration]

Eplicitly forbidden:

• all Any* types Iec022
• Structures [Structure] or Arrays [Array] Iec022
• IecStringEx, IecString80, IecWString, IecWString80 TODO-LINKING

Solution

Change the return type to one of the explicitly allowed types.
