Assignment of the control interface

Control interface
The user program uses the control interface to influence the behavior of the technology
inputs and technology outputs at interface X142.
The following table shows the control interface assignment:
Table 7- 7 Assignment of the control interface
Offset from Parameter
start address
Byte 0 SET_DQ (DQ0 to DQ7)
Byte 1 to 3 Reserved
Byte 4 to 7 TEC_OUT (DQ0)
Byte 8 to 11 TEC_OUT (DQ1)
Byte 12 to 15 TEC_OUT (DQ2)
Byte 16 to 19 TEC_OUT (DQ3)
Byte 20 to 23 TEC_OUT (DQ4)
Byte 24 to 27 TEC_OUT (DQ5)
Byte 28 to 31 TEC_OUT (DQ6)
Byte 32 to 35 TEC_OUT (DQ7)
Byte 36 SEL (DI0, DI1)
SIMATIC Drive Controller
System Manual, 11/2019, A5E46600094-AA
Meaning
Set DQ (DQ0 to DQ7)
Must not be used
Timer DQ:
Byte 0, 1: OFF TIME (output time stamp for DQ reset)
Byte 2, 3: ON TIME (output time stamp for setting DQ)
Oversampling DQ:
Byte 0 to 3: 32 states for oversampling
Pulse width modulation (PWM):
Byte 0 to 3: PWM bit pattern
See Byte 4 to 7
SEL DI1 Bit 5 to 7: Edge selection for time stamp acquisition DI1
001 Rising edges only
010 Falling edges only
011 Rising and falling edges
(in order of occurrence)
101 First rising, then falling edge
110 First falling, then rising edge
000, 100, 111 reserved
Bit 4: Cyclical time stamp acquisition for DI1
SEL DI0 Bit 0 to 3: see SEL DI1
