2.9.5 Execution from external source (buffer size and number)
Application
Individual machining steps for producing complex workpieces may involve program
sequences that require so much memory they cannot be stored in the NC memory. This type
of program can be selected and executed from an external device in "Execution from
external source" mode. This "external device" takes the following form with HMI Advanced
and with HMI Embedded:
HMI Advanced: HMI Embedded:
Local hard disk or ATA card or a
Network drive Network drive
Functions
In principle, any program that is accessible via the directory structure of the data
management system of the HMI operator interface can be selected and retroloaded.
• Execution from external source via V24 interface:
In HMI Embedded, the "Execution from external source" softkey can be used to transfer
external programs to the NC via the V24 interface.
• External subroutine:
Executing a subroutine in "Execution from external source" mode.
The "external" subroutine is called via part program command EXTCALL with
specification of a call path (optional) and the subroutine identifier.
• Modal execution from external source:
Retaining the selection "Execution from external source" after Reset or part program end.
Deselection by next program in NC memory:
If a program was selected on the HMI for "Execution from external source", this condition
remains active after a Reset/end of part program. "Execution from external source" mode
is not deselected until another program stored in the NC memory is selected for
execution.
