Parameter and type
REQ Input
INTERFACE Input
CONF_DATA Input
DONE Output
BUSY Output
ERROR Output
STATUS Output
ERR_LOC Output
The IP configuration information is placed in the CONF_DATA data block, along with a
Variant pointer on parameter CONF_DATA referenced above. The successful execution of
the T_CONFIG instruction ends with the handover of the IP configuration data to the network
interface. Errors are assigned to the STATUS output parameter.

Description
No error
Note: If the instruction executes successfully, the "no error" status may not be returned.
The job is not finished (BUSY = 1).
Start of job execution
Description
Use the T_CONFIG instruction to change the IP
configuration parameters from your user program.
T_CONFIG works asynchronously. The execution
extends over multiple calls.
Description
Starts the instruction on the rising edge.
ID of network interface
Reference to the structure of the configuration data;
CONF_DATA is defined by a System Data Type (SDT).
0: Job has not yet started or is still running.
•
1: Job was executed without error.
•
0: The job is complete.
•
1: The job is not yet complete. A new job cannot be
•
triggered.
Status parameters with the following values:
0: No error
•
1: Error occurred during processing. STATUS provides
•
detailed information on the type of error.
Status information including error information. (Refer to
the Error and Status condition codes in the table below.)

parameter)
