Data type

Description

INTERFACE_ID

IN

HW_ANY

Hardware identifier of the used interface

CON_ID

IN

CONN_OUC

Unique connection ID of the send block (TSEND_C)

LOCAL_PORT

IN

UINT

Local port number

RESET_CON

IN

BOOL

FALSE: no reset (default)TRUE: reset of the communication connection

REQ_DB

INOUT

DB_ANY

DB of the ibaPDA communication interface ibaREQ_DB

ERROR_STATUS

OUT

WORD

Internal error code

LOST_SAMPLES

OUT

UNIT

Counter for lost measurement values

The following SIMATIC standard blocks are used internally:

  • TCON

  • TUSEND

  • TDISCON
Detailed description

INTERFACE_ID

Hardware identifier of the used interface.

CON_ID

Unique reference to the connection to be set up, value range: 1 to 4095.

LOCAL_PORT

Number of the locally used port

RESET_CON

Used for manually resetting the communication connection.

REQ_DB

The DB is used for data exchange with ibaPDA. For all related Request blocks, configure the identical DB.

ERROR_STATUS

Internal error of the block. If there is no error, the value 0 is output.

LOST_SAMPLES

The counter is incremented with every call of the block if no new UDP telegram can be sent to ibaPDA, as the previous send order has not been finished, yet. A continuously rising value indicates a shortage in the communication performance.
Error codes

Hexadecimal value ERROR_TSEND

Description

W#16#80A1

The specified connection or the port is already used by user. Communication error:

  • The specified connection has not yet been established.

  • The specified connection is being terminated.

  • Transfer via this connection is not possible.

  • The interface is being re-initialized.

W#16#80A3

The nested T_DIAG instruction has reported that the connection has closed.

W#16#80A4

IP address of the remote connection endpoint is invalid, or it matches the IP address of the local partner.

W#16#80A7

Communication error: You called the instruction with COM_RST = 1 before the send job was complete.

W#16#80AA

A connection is currently being established with the same connection ID by another block. Repeat the job with a new rising edge at the REQ parameter.

W#16#80B6

Parameter assignment error in the connection_type parameter of the data block for connection description.

W#16#80B7

Error in one of the following parameters of the data block for connection description: block_length, local_tsap_id_len, rem_subnet_id_len, rem_staddr_len, rem_tsap_id_len, next_staddr_len.

W#16#8085

The LEN parameter is greater than the highest valid value.

W#16#8086

The ID parameter within the CONNECT parameter is outside the valid range.

W#16#8087

Maximum number of connections reached; no additional connection possible.

W#16#8088

The value at the LEN parameter does not correspond to the receive area set at the DATA parameter.

W#16#8091

Maximum nesting depth exceeded.

W#16#809A

The CONNECT parameter points to a field that does not match the length of the connection description.

W#16#809B

InterfaceID is invalid. It does not point to a local CPU interface or a CP or has the value "0".

W#16#80C3

  • All connection resources are in use.

  • A block with this ID is already being processed in a different priority group.

W#16#80C4

Temporary communication error:

  • The connection cannot be established at this time.

  • The interface is receiving new parameters or the connection is being established.

  • The configured connection is being removed by a TDISCON instruction.

  • The used connection is being terminated by a call with COM_RST = 1.

W#16#80C6

Remote network error: The remote partner cannot be reached.
