Index 8pp0 MTI settings (for 08 ≤ pp ≤ 0F; Ch. 1 to Ch. 8)
Index (hex) Name Meaning Data type Flags Default
8pp0:0 MTI settings UINT8 RO 0x14 (20
dec
)
8pp0:01 Enable digital filter Activation of the filter to hide spikes. The filter length
should be entered in 8pp0:14 "DigitalFilterCount" (
fur-
ther explanation see here [ } 123] ).
BOOLEAN RW 0x00 (0
dec
)
8pp0:11 Buffer reset behavior Specifies the behavior of the "Input buffer reset" bit
Permitted values:
UINT16 RW 0x0000 (0
dec
)
0 Reset on rising edge: The buffer is cleared with a
rising edge of "Input buffer reset"
1 Reset on high level: The buffer is cleared with a
rising edge of "Input buffer reset" and does not
accept new values until "Input buffer reset" is re-
set.
8pp0:12 Buffer mode Specifies whether handshaking is to be used for re-
trieving the values from the buffer (transmission in-
tegrity) or whether new values are to be transferred di-
rectly with each PLC cycle (faster).
Permitted values (further explanation see here) [ } 122] :
UINT16 RW 0x0001 (1
dec
)
0 Asynchronous (Buffered): The arrival of new
events must be acknowledged by the PLC. To
this end the byte "No of input events" must be
monitored in the PLC program. If it is greater
than zero the pending events can be taken over
from the process image. Subsequently the byte
"Input order counter" must be incremented. This
signals the terminal that the events were ac-
cepted and new data can be created in the next
cycle.
1 Synchronous: New events are automatically
transferred with each PLC cycle
8pp0:13 Buffer overflow behav-
ior Specifies the behavior in the event of buffer overflow
Permitted values:
UINT16 RW 0x0000 (0
dec
)
0 Lock buffer: New events are discarded
1 Overwrite oldest event: New events overwrite the
last events in the buffer
8pp0:14 Digital filter count Defines the number of event samples to ensure trans-
fer into the buffer
(further explanation see here) [ } 123] .
