SIPLUS RIC IEC on S7 V1.5

Functional description

Parameter blocks which include an enumeration are constructed so, that more than

one data block can be used if required. The following information is required for

management.

Currently the DB management is not used – for this reason all parameters can be left

at their default settings (0)

Number (1 – n) of the current data block for the parameter block

0: not used

Total number (n) of data blocks for the parameter block

0: not used

DB number of the current data block

0: not used

DB number of the previous data block, if one exists.

Otherwise: 0

DB number of the subsequent data block, if there is another one.

Otherwise: 0

Parameter blocks containing an enumeration have one information block 'Info man-

agement'. It contains following information

The values of the information management parameters are already preset and there-

fore do not need to be modified.

Byte position of the first data record in this DB, may not be changed

Number of data records contained in this DB

0: unspecified -> the data block end marks the last data record

0: no sorting (default setting)

4: the first 4 bytes of the information specific parameter (see parameter group

IEC_Addr) form the sorting criteria

Other sorting lengths are not permitted

If very much parameter blocks are needed it is recommended to deposit the parame-

ter blocks ascending sorted according to ‚T101_104_IOA'. A so applied data block

will be scanned more effective in conjunction with ‚Len_Sort_Key' = 4 (binary scan)

These parameters are type specific. Its function is described at this place only par-

tially.

You find supported values in the corresponding chapters for block description

Internal used. Don't change the identification for this parameter DB!

Internal used. Lastly processed information – don't change!

Create any amount of parameter blocks by setting the array value n in the declara-

tion view accordingly. In the detail view the parameters can be individual adjusted.

In this case for each desired command a parameter block has to be created. There

the allocation of control bit to command and the complete description of the com-

mand with all its attributes are carried out statically.

IEC101/104 information object address (IOA) which is expected in the command

message to be received from source.

IEC101/104 information object address (IOA) for the transfer of the command mes-

sage to the destination. If ‚0' is specified her, the transfer is carried out with the re-

ceived address.
