7-420 SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
7.5 External STOPs
This example is based on the configuring example in Section 7 "Safety
Integrated without SPL", although external STOP C is to be used for all the
drives on the example machine. A small SPL has to be written for this problem
because external STOP A must be supplied from a system variable
($A_OUTSI). In this case, no hardware of the NCK-SPL has to be assigned by
the machine data 10390/10392, nor does the machine data parameterized in
Section 7 "Safety Integrated without SPL" have to be changed.
Task/structure:
External STOP C is to be activated for X, Z, C when the light barrier is
triggered. The light barrier is analyzed by an external unit. The light barrier is
also acknowledged by a switch that is connected to this evaluation unit. In order
to test the external STOP C the two switching contacts for the PLC I/Os and the
NCK I/Os are supplied with +24 V by two separate PLC outputs (A36.0/A36.1)
(refer to circuit diagram).
The logical drive number for the terminal block is 4 and the input module used
is inserted into slot 1 in the terminal block.
Commissioning is explained step-by-step with reference to the previous
sections in Chapter 7.
1. Enable the function "SBH/SB monitoring" and "external STOPs" for drives
X, Z, C via the axis-specific machine data
36901: SAFE_FUNCTION_ENABLE = 41 H
2. Set the machine data 11602: ASUP_START_MASK=7: ASUB start in all
operating states of the NC (RESET/JOG/not all axes referenced/read-in
inhibit active).
3. Set machine data 11604: ASUP_START_PRIO_LEVEL=1: (interrupt
priority from which MD $MN_ASUP_START_MASK is active).
4. Enter axis-specific machine data for drives X, Z, C
36977: SAFE_EXT_STOP_INPUT[0]: 04010101H (STOP A is supplied
from $A_OUTSI[1] in the SPL)
36977: SAFE_EXT_STOP_INPUT[1]: 01040101H (first input on the
DMP input module)
36977 SAFE_EXT_STOP_INPUT[2]: 80000000H (STOP D statically
de-selected).
5. The other safety machine data are parameterized as described in
Chapter 7, "Safety Integrated without SPL".
6. The following program has to be written for the PLC:
SET
= DB18.DBX62.0 // Supply OUTSIP[1]
= DB31.DBX32.2 // Supply STOP A for axis X
= DB32.DBX32.2 // Supply STOP A for axis Z
= DB33.DBX32.2 // Supply STOP A for spindle C
//
U I 32.0 // PLC input / light barrier
evaluation unit
= DB31.DBX32.3 // Supply STOP C for axis X
= DB32.DBX32.3 // Supply STOP C for axis Z
= DB33.DBX32.3 // Supply STOP C for spindle C
//
