Configuring the HMI system
2.1 Processing INI files
; switched "OFF" by value "False" or if named argument
; does not exist in line.
; "EnableAllTogetherWriteToNcdde := True":
; all data in one ncdde variable
; "EnableSingleWriteToNcdde := True":
; one ncdde variable per data
; Both options can be active.
; If both options are not active,
; no write to ncdde variables will occur.
; "WriteChangesWhenStateChanged := True":
; write changes when a softkey is pressed,
; even if there is no switch to WIZARD
The following setting must be in a single line of PARAM.INI:
HMICurDataInterface = EnableAllTogetherWriteToNcdde := True,
EnableSingleWriteToNcdde := True,
WriteChangesWhenStateChanged := False
2.1.15 Executing from the hard disk (m:n configuration)
Requirements
This function applies to SINUMERIK powerline only.
Included in the NETNAMES.INI file are descriptions of the following:
● Configuration of assignments of multiple HMI components and multiple NCU components
● Configuring the channel menu for multi-channel systems
● Reference to file with symbols for PLC signals
Function EXTCALL
In order to execute external programs that are located on the hard disk of the PCU in the
data management system from the part program using the EXTCALL program command,
the following entries, for example, are required in the section [conn HMI_x] of the
NETNAMES.INI file.
; HMI identification part
[own]
owner= HMI_3
; Description of possible connections
; Connection part
[conn HMI_3]

(m:n configuration).
If, for example, multiple HMI components have been assigned to one NCU, the unit that
is to provide the part program in the event of "Execution from external source (hard disk)"
must be specified.
