Description
This Function Block is used to configure the behaviour for the analog output mod-
ules of the sigmadue
I/O
series of Ascon SpA in case of failure of the CAN com-
munication. Using this function block the user is able to activate the capability of
the CAN node to manage the error condition. Ascon SpA strictly recommends to
use as a diagnostic system the
NodeGuarding
protocol in order to process cor-
rectly the error condition (for more details about the diagnostic protocols available
on
sigmaPAC
, please refer to the
CU-02
User Manual).
When a communication error occurs, each module for each channel can set
automatically the output to a predefined value. The
MODE
parameter defines the
behaviour for each channel: if the
n-th
bit is
0
in case of error the output remains at
the actual value; if the
n-th
bit is
1
the output assume the value passed with the
input
EVALn
in case of error (where n is the channel). See the “
Mode Parameter
”
section.
