Beispiel:
CAN bus timeout
Define the timeout time for the CAN input (minimum value: 5 minutes).
As long as the information continues to be read from the CAN bus, the
network
error
for the CAN
input will be "
No
".
If the value has not been updated for longer than the set timeout, the
network
error
changes from
"
No
" to "
Yes
". You can then define whether the controller should issue the last value transmitted or a
definable substitute value (only when the measured variable is set to
User
).
The
network
error
can be selected as the source of a function input variable, which allows the con
-
troller to react appropriately to a failure of the CAN bus or transmission node.
In
System values
/ General, a network error for
all
CAN inputs is available.
Sensor check
If you set "Sensor check" to "Yes", the sensor error of the sensor supplying the CAN input is available
as an input variable for a function.
Measured variable
If "Measured variable" is set to "
Automatic
", the unit of measurement specified by the transmission
node will be applied in the controller.
If you select "
User
", you can select a unit of your own, a sensor correction and, if sensor check is ac
-
tive, a monitoring function.
Every CAN input is assigned its own unit, which can differ from the unit used by the transmission
node. A range of units is available to choose from.
This setting is only displayed if "Measured variable" is set to "
User
".
