Activating The Technological Function; Configuring The Memory; Parameterizing The Digital On-Board Outputs - Siemens sinumerik 840D sl Function Manual

2.2.1

Activating the technological function

The technological function is activated via the following machine data:
MD60900 $MN_CC_ACTIVE_IN_CHAN_HSLC[0], bit 0 = 1 (activation of the technology in
NC channel 1)
Note
The technological function is only available in the 1st channel of the NC.
2.2.2

Configuring the memory

Memory configuration
The technological function requires additional data in the NCK-internal block memory. The
following memory-configuring, channel-specific machine data must be parameterized:
• MD28090 $MC_MM_NUM_CC_BLOCK_ELEMENTS (number of block elements for
• MD28100 $MC_MM_NUM_CC_BLOCK_USER_MEM (size of block memory for compile
See note.

Note
The specified values must be entered in addition to the existing machine data value x.
2.2.3

Parameterizing the digital on-board outputs

Digital output
A digital output from the local I/O is required for the switching signal. The following machine
data must be used to parameterize at least one digital output byte:
MD10360 $MN_FASTIO_DIG_NUM_OUTPUTS ≥ 1 (number of active digital output bytes)
Special functions: Cycle-Independent Path-Synchronous Signal Output (TE8)
