SIPLUS RIC IEC on S7 V1.5
Functional description
Without application of a parameter-DB:
Value of the address of the last 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
With application of a parameter-DB:
Number of the information to be processed.
The associated parameters
First_IOA_or_Para_DB_No).
P_Application_Dst 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.
,P_Application_Dst' has to be connected with the ‚S7_IEC_Config' block' which
transmits the messages to the subordinated station (RTU). Usually this is the
S7_IEC_Config in the Master configuration.
Value of the address from the application service data unit, which is the destination of
the command messages.
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.
Blocking input for all commands processed from this block.
FALSE: New commands are executed.
TRUE: New commands are not executed and negatively acknowledged.
Selection whether a command has to be completed with or without transmission of
‚Termination' of activation.
FALSE: without‚Termination of activation'
TRUE: with ‚Termination of activation' (default adjustment)
Supervisory time in seconds.
Within this time a confirmation of the activation (COT=7) is expected. Otherwise the
command is negatively acknowledged.
Supervisory time in seconds.
Within this time the end of the activation (COT=10) is expected. Otherwise the com-
mand is negatively acknowledged. This time has to be selected slightly longer than
the output time of the command in the subordinated station.
The parameter defines the maximum number of buffered commands
0 without command buffer (like V1.1)
>0 maximum number of buffered commands
In this case a command buffer DB will be created during the runtime
An entry into the command buffer DB happens only if during arrival from an impulse
command another impulse command already runs.
Command output (impulse command) running.
The output is set for the duration of the command output if an impulse command is
emitted via this block.
Defines the number of the command buffer DB
The size of the command buffer DB will be fixed with ‚Cmd_Buffer_Dim'.
