1. General

3.1.1.1. Nodal block MAoSLi_MD_pDB (FB161)

The block has to be embedded between ‚SL_ORG_ASDU' of the target application (Slave) and

‚S7_IEC_Config' of the source application (Master).

The block transfers the information received by telecontrol messages from the Master connection to the

Slave connection. In the simplest case it is carried out "transparent" i.e. the information are transferred 1

to 1 without any pre-processing.

Illustration as CFC-block with default values

Important features are:

 With minor effort of parameterization much information (‚max_No_of_Images') can be pro-

cessed:

- Single indication with TK 1,2,30

- double indication with TK 3,4,31

- transformer tap with TK5,6,32

- Bit pattern with TK7,8,33

 Readings for the default adjustments can be taken from the corresponding variable comment.

On the other hand only a minimum of mandatory inputs are required.

The interconnection of ‚P_Application_Src', ‚ASDU_Adr_Src' and ‚P_SLi' is a minimum require-

ment.

 automatic update of the image-DB with filter possibility for

defined address bands with ‚First_Info_Adr_Src', ‚Last_Info_Adr_Src'

certain information types with ‚Filt_15_13_11_9_7_5_3_1'

 Adjustable processing per information type

- Priority

- time stamp

- GI (in parallel to the general interrogation (GI) a group interrogation is supported)

- Transfer also without changes

 Automatic designation of all information with status not topical (NT) in case of disturbed connec-

tion to the subordinated station.

 Optional assignable parameter block for

Individual quantity structure

Address conversion (of the information object address)

parameterizable threshold for measured values per information

possibility of image access (diagnosis / further processing)
