Assignment of the feedback interface

Feedback interface
The user program receives current values and status information from the X142 interface
technology I/Os over the feedback interface.
The following table shows the feedback interface assignment:
Table 9- 11 Assignment of the feedback interface
Offset from Parameter
start address
Byte 0 STS_DI (DI0 to DI7)
Byte 1 to 3 Reserved
Byte 4 to 7 TEC_IN (DI0)
Byte 8 to 11 TEC_IN_EXT (DI0)
Byte 12 to 15 TEC_IN (DI1)
Byte 16 to 19 TEC_IN_EXT (DI1)
192
Meaning
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
See byte 36
MSL Bit 12 to 15: Sign of life counter (master sign of life)
--- Bit 1 to 11: Reserved; bits must be set to 0
SYN Bit 0: Synchronization of X142 interface with the user program
Meaning

Byte 2, 3: 1st TIME/ON TIME (first input time stamp)
Oversampling DI:
Byte 0 to 3: Oversampling value
Event/period duration
measurement
See byte 4 to 11
Event measurement:
Byte 0, 1: Reserved
Byte 2, 3: Counter value
Time period measurement:
Byte 0 to 3: Measured time period
