# Description

P-CHAN-00158 | Program name for automatic streaming
Description | When this program is opened as a main program or a subroutine, the ASCII data is not read in from the file system, but is requested from the data streaming interface. The data input is therefore diverted transparently to the streaming interface.

If the program name is not entered, the streaming function can not be activated

Parameter | streaming_prog_file
Data type | STRING
Data range | <empty_string>: Streaming function deactivated (default). <prog_name>: Name of the file (main program/global subroutine) that automatically triggers a changeover to streaming mode when it is started.
Dimension | ----
Default value | *
Remarks | Parameterisation example: streaming_prog_file streaming.nc (name of streaming program) * Note: The default value of variables is a blank string.

Data stream for incremental program commanding
Description | This COM interface object can write the data stream with incremental NC commands. One complete NC line must always be written. Several NC lines may also be written jointly in one write access. Each NC line must be terminated by a carriage return (ASCII value = 13) and line feed (ASCII value = 10).
Type | String; the string length depends on the application
Value range | ASCII characters
HMI elements | mc_program_stream_w
Access | Read, write
IndexOffset | 0x90 (IndexGroup = 0x000201<ii> where <ii> = channel)
