SIPLUS RIC IEC on S7 V1.5

Functional description

Block identifier for (actual only internal) diagnostic functions. Assign different numbers

within one block type as byte variable e.g. B#16#1

DB-No. of the dedicated parameter - / image data block.

the parameter-/ image data block is created automatically during

process. Size correspondent to max_No_of_Images

>0:

Number of the parameter-/ image data block to be used

Size of the dynamically generated image data block.

The use of the memory per information object is 44 Byte.

At CPUs supporting a DB size of 16kByte  max. 371

at CPUs supporting a DB size of 64kByte  max. 1489

with one FB call.

With corresponding capable CPUs the amount of information can be increased by

multiple call of the FB.

P_Application is a pointer on a common data range from ‚S7_IEC_Config' block.

Therefore it must be interconnected via a DWord variable with its output

‚P_Application'. Via this pointer resp. the data range behind, application data like

ASDU address, receive buffer etc. are handed over to the config block.

Value of the address from the application service data unit, which is the source of the

information.

Permissible range for the length of the ASDU address 1 byte is 1 up to 254

Permissible range for the length of the ASDU address 2 byte is 1 up to 65534

The broadcast addresses 255 (FFh if length 1) resp. 65535 (FFFFh if length 2) are

always accepted.

Value of the address of the first information object processed from the block

Permissible range for the length of the IOA address 1 byte is 1 up to 255

Permissible range for the length of the IOA address 2 byte is 1 up to 65535

Permissible range for the length of the IOA address 3 byte is 1 up to 16777215

If the information object address exists in structured form (3 octets), it has to be con-

verted into a decimal number:

IOA dec = octet1 + 256*octet2 + 256*256*octet3

Together with ‚Last_Info_Adr_Src' it is possible to filter on defined address ranges.

Value of the address from the last information object processed from the block

Permissible range for the length of the IOA address 1 is 1 up to 255

Permissible range for the length of the IOA address 2 is 1 up to 65535

Permissible range for the length of the IOA address 3 is 1 up to 16777215

If the information object address exists in structured form (3 octets), it has to be con-

verted into a decimal number:

IOA dec = octet1 + 256*octet2 + 256*256*octet3

Together with ‚First_Info_Adr_Src' it is possible to filter on defined address ranges.

Priority of transmission with Prio L / H: 0 (highest) - 15 (lowest) Default = 0

Filter for the processible information types.

Set bits unlock the processing for the allocated information types. The numbers in the

parameter name respond to the basis TK (without time).

Allocation of the parameter bits to the TKs:

With the default adjustment (B#16#FF) all TKs are forwarded.

P_SLi is a pointer to a common data range from ‚SL_ORG_ASDU', block. Thus it has

to be interconnected with its output ‚P_SLi' via a DWord variable.

Via this pointer resp. the data range behind values like ASDU address, actual time

stamp, send buffer etc. are taken over from ORG block as well as general interroga-

tions are processed.
