Iso Dialect Mode; Switching Between Siemens And Iso Modes - Siemens SINUMERIK 808D Programming And Operating Manual

2.1.2

ISO dialect mode

The following conditions are valid in the active ISO dialect mode:
● ISO dialect mode can be set with machine data as the default setting of the control system. The control system reboots
by default in ISO dialect mode subsequently.
● Only G functions from the ISO dialect can be programmed; programming of Siemens G functions is impossible in ISO
Mode.
● The ISO dialect and Siemens language cannot be mixed in the same NC block.
● G commands cannot be used to switch between ISO dialect M and ISO dialect T.
● Subroutines that are programmed in Siemens mode can be called.
● If Siemens functions are to be used, switch the control system to Siemens mode first.
Note
Switching from Siemens mode to ISO dialect mode does not change the default value 0x04 of MD10890
EXTERN_TOOLPROG_MODE.
0x04: select the tool offset only with an H number in ISO dialect mode.
•
0: select the tool offset only with a D number in ISO dialect mode.

2.1.3

Switching between Siemens and ISO modes

The control system supports the following two programming language modes:
● Siemens language mode
● ISO dialect mode
Note that the active tool, tool offsets and workpiece offsets are not influenced by the mode changeover.
Switchover through G functions
The following G functions can be used to switch between Siemens mode and ISO dialect mode:
● G290 - Siemens NC programming language active
● G291 - ISO Dialect NC Programming language active
G290 and G291 must be programmed alone in an NC block.

1. Select the desired operating area.
2. Press this softkey on the PPU. The control system automatically starts the mode change
from Siemens mode to ISO dialect mode. After the changeover, "ISO" is shown on the up-
per left corner of the screen.
To change from ISO mode back to Siemens mode, press the same softkey again.
