MTI outputs

•
InputBufferReset
TRUE: The channel buffer is cleared. This can make sense, e.g. in the case of a
reported
InputBufferOverflow
, if the application requires this. Via the CoE setting
0x80n0:13
BufferOverflowBehavior
the behavior on buffer overflow can be specified.
• InputOrderCounter
:
This counter is only for the asynchronous operation. Only if the counter is
incremented by the controller, the channel outputs a new set of events to the fieldbus.
Each CoE channel (from 0x8000) has settings for
operating mode selection

Description
0x80n0:01
Enable digital
filter
Activation of the filter for hiding spikes. The filter
length can be entered in
0x80n0:14
DigitalFilterCount
.
0x80n0:01
FALSE
Filter is deactivated
0x80n0:01 TRUE
Activation of the input filter
0x80n0:11
Buffer reset
behavior
Reset behavior in the event of a reset signal in the
status register (PDO)
0x80n0:11
FALSE
reset on rising
edge
Reset is executed on rising edge. New data can then
be buffered right away.
0x80n0:11 TRUE reset on high
level
Buffer is held in reset as long as the signal is active.
Can be used for muting, for example.
0x80n0:12
Buffer mode
Setting of asynchronous or synchronous operation
0x80n0:12
FALSE
Asynchronous
(Buffered)
Asynchronous operation. To load the buffer entries
into the PDO, the PLC has to increment the
InputOrderCounter [
}
119]
. This
handshake
requires
one cycle for processing. The data are retained in the
event of telegram malfunctions.
0x80n0:12 TRUE Synchronous
Synchronous operation. The first buffer entries are
transferred cyclically to the PDO, as soon as data are
available.
0x80n0:13
Buffer overflow
behavior
Configuration of the behavior if more than 32 events
per channel have to be stored
0x80n0:13
FALSE
Lock buffer
Overwriting of data is blocked, new events will be
lost.
0x80n0:13 TRUE Overwrite oldest
event
The oldest data are overwritten, new events are
retained.
0x80n0:14
Digital filter count
Number of microcycles until an applied input level as
evaluated as valid. In this way spikes are filtered out.
An entry of 1 results in disabling of the filter.
