E_SoE_AttribLen
The enumeration E_SoE_AttribLen in the attribute of a parameter specifies whether the value of the parameter is a 2, 4, or 8-byte data type (single value), or whether it is a list consisting of 1, 2, 4, or 8-byte data types. List types (with eSoE_LEN_V...) first have the current list length in bytes (in a 16 bit value), then the maximum list length in bytes (in a 16 bit value) and the actual list in the specified data type.
Sample: see ST_SoE_String of the eSoE_LEN_V1BYTE type.
TYPE E_SoE_AttribLen : (
eSoE_LEN_2BYTE := 1,

eSoE_LEN_V1BYTE := 4,
eSoE_LEN_V2BYTE := 5,
eSoE_LEN_V4BYTE := 6,
eSoE_LEN_V8BYTE := 7
