TE8: Cycle-independent path-synchronous switching signal output

16.3 Start-up

16.3 Start-up
16.3.1

Activation

Before starting up the technological function, make sure that the corresponding compile cycle
has been loaded and activated.
See also "TE01: Installation and activation of loadable compile cycles [Page 433]".
Activation
The "Cycle-independent path synchronized switching signal output" technology function is
activated via the following machine data:
MD60948 $MN_CC_ACTIVE_IN_CHAN_HSLC[0], Bit 0 = 1
Note
The "Cycle-independent path-synchronized switching signal output" is available only in one
channel of NC.
16.3.2

Memory configuration

The "Cycle-independent path synchronized switching signal output" technology function
requires additional memory area in the NCK internal block memory.
No. of block elements
The number of the block elements that can be used for compile cycles is set via the memory
configuring channel-specific machine data:
MD28090 $MC_MM_NUM_CC_BLOCK_ELEMENTS
The already existing machine data value (x) is adjusted as follows for the "Cycle-independent
path synchronized switching signal output" technology function:
MD28090 $MC_MM_NUM_CC_BLOCK_ELEMENTS = x + 1
Size of the block memory
The size of the block memory in KB that can be used by the user for compile cycles is defined
via the memory configuring channel-specific machine data:
MD28100 $MC_MM_NUM_CC_BLOCK_USER_MEM
The already existing machine data value (x) is adjusted as follows for the "Cycle-independent
path synchronized switching signal output" technology function:
MD28100 $MC_MM_NUM_CC_BLOCK_USER_MEM = x + 10
