3-12 Digital Input/Counter Functional Block
the Analog network variable. The offset may be
positive or negative. The units match the units being
sent on the Analog network variable. The offset is
applied after the translation.
Minimum Value This parameter is only used if the Frequency
processing option is being used. This value
determines the minimum value that will be sent by
the Analog network variable. If this limit is exceeded
the output will be clipped at this limit.
Maximum Value This parameter is only used if the Frequency
processing option is being used. This value
determines the maximum value that will be sent by
the Analog network variable. If this limit is exceeded
the output will be clipped at this limit.
Send on Delta This parameter is only used if the Count, Repeating
Count
, On Time, or Frequency processing option is
being used. The sensed value must change by at least
this amount before a new value is sent. A new value
will still be sent if the heartbeat time expires.
Analog Override This parameter is only used if the Count, Repeating
Count
, On Time, or Frequency processing option is
being used. This value determines the value that will
be sent by the Analog network variable if this
functional block is put into override.
Digital Override This parameter is only used if any processing option
other than Frequency is being used. This value
determines the value that will be sent by the Digital
network variable if this functional block is put into
override.
Heartbeat Determines how often the functional block sends a
heartbeat over the network over each of its output
network variables. The behavior of the system in case
of a missed heartbeat is determined by the functional
blocks which fail to receive the heartbeat. Setting
this property to 0 disables the heartbeat for this
functional block. Disabling the heartbeat causes the
output network variable to only be transmitted in
response to a changed hardware input value.
Throttle Limits how often data is sent over the network.
Setting this property to 0 disables throttling.
Status
This tab allows you to view and change the status of a Digital Input/Counter
functional block. See Status in Chapter 2 for more information.
