Resu Main Program Memory Area - Siemens sinumerik 840D sl Function Manual

Memory configuration
By default, RESU requires the following compile cycles heap memory:
• MD28105 $MC_MM_NUM_CC_HEAP_MEM = x + 50(heap memory in KB for compile
• MD62571 $MC_RESU_RING_BUFFER_SIZE = 1000 (size of the block buffer / ring buffer
• MD62572 $MC_RESU_SHARE_OF_CC_HEAP_MEM = 100 (RESU share of total heap
Fault messages
The block search buffer requires at least 2160 bytes (corresponding to 12 subroutine calls
with 180 bytes each). Otherwise, the following alarm will be generated during NC power-up:
• Alarm "75600 Channel 1 retrace support: Incorrect MD configuration, error no. 5"
If the block search buffer is not big enough during operation, the following alarm appears:
• Alarm "75606 Channel 1 retraceable contour shortened"
2.2.4

RESU main program memory area

Meaning
The following machine data can be used to set the storage location for the RESU main
program CC_RESU.MPF (see Subsection "Detailed description / RESU-specific part
programs / Main program (CC_RESU.MPF)"):
• MD62574 $MC_RESU_SPECIAL_FEATURE_MASK, bit 1 = 0 (additional RESU features)
• MD62574 $MC_RESU_SPECIAL_FEATURE_MASK, bit 1 = 1
DRAM memory configuration
If the RESU main program is created in the dynamic memory area of the NC, the available
dynamic memory area of the NC must be enlarged:
• MD18351 $MN_MM_DRAM_FILE_MEM_SIZE = x + 100 (size of part program memory
Special functions: Retrace Support (TE7)
