Function-Specific Display Data; Channel-Specific Gud Variables - Siemens sinumerik 840D sl Function Manual

Detailed description

2.6 Function-specific display data

Activation
Activation of the block search from the last main block is performed using the following
RESU-specific machine data:
• MD62575 $MC_RESU_SPECIAL_FEATURE_MASK_2, bit 0 (additional RESU features)
Boundary conditions
In order that a new retrace support operation can take place following a retrace support
operation with block search from last main block, the RESU start CC_PREPRE(1) must be
programmed in the retrace support ASUB CC_RESU_BS_ASUP.SPF:
Example:
PROC CC_RESU_BS_ASUP SAVE
M17

Channel-specific GUD variables

As display data for the size of the block search buffer, RESU provides the following channel-
specific GUD variables for HMI applications:
• SINUMERIK HMI Advanced
• SINUMERIK HMI Embedded
Table 2-1
GUD variable
CLC_RESU_LENGTH_BS_BU
FFER
Once the technological function has been started up successfully, the GUD variables listed
are not displayed automatically on the HMI interface.
30
– Bit 0 = 0: Retrace support is performed using block search with calculation on contour
– Bit 0 = 1: Retrace support is performed using block search from the last main block
; (synchronized actions, M functions, etc. required for retrace support
)
