Meaning
DataType
Specification of the data type of the parameter to be read and the output at which the
parameter is made available:
● 0 = no data type selected
● 1 = data type ’OctStr’ (Simatic: Array of Byte)
● 2 = data type ’VisStr’ (Simatic: String)
SlotNo
Number of the slot in HW Config, which is assigned the data record
AbsInd
Absolute Index (= number) of the data record
LenDr
Length in bytes of the data record
StrLen
Total length of the string to be read
1)
Offset
Start address of the parameter in the read data record, e.g. as of byte 12
1)
Total length of the string to be read:
Note
For string with a length of 16 bytes and Simatic format, for example, you must parameterize 18
bytes accordingly because bytes 0 and 1 also contain the maximum and current length of the
string.
