SINUMERIK 840Di sl Manual (HBIsl) – 01/2007 Edition
Alarm and Message Texts
12.1 Alarm and message texts
To enable easy adaptation of alarm and message texts to the specific require-
ments of an automation system, the alarm and message texts are stored in
freely accessible ASCII text files.
The alarm and message texts contained in the text files are used commonly by
all SINUMERIK user interfaces:
S SinuCom NC
S 840Di start–up
S HMI Advanced
By changing/modifying the texts or files or by creating new texts/files, a flexible
adaptation to the current requirements is possible.
Files containing the alarm and message texts are stored on the hard disk in
directory <installation path>\dh\mb.dir\.
12.1.1 Configuration file MBDDE.INI
The alarm and message texts to be used are set in the file <installation
path>\mmc2\mbdde.ini. For this purpose, the appropriate paths to the applica-
tion–specific standard and user files must be stored in the [Textfiles] section of
file MBDDE.INI.
