4.2.1.6 PLC Settings
You can make the basic settings for the configuration of the PLC here, for example the handling of inputs and outputs
and the bus cycle task.

Application for I/O handling
Item Description
Application for I/O handling
Application that is for the I/O handling.
➁
PLC Settings
Item Description
Update IO while in stop
: DIADesigner-AX does not refresh the values of the input and output channels
when the PLC is in the stop state.
: DIADesigner-AX refreshes the values of the input and output channels even if
the PLC is in the stop state. If the watchdog detects a malfunction, the outputs
are set to the predefined default values.
Behavior of the outputs in
stop
Handling of the output channels when the controller enters the stop state:
•
Keep current values: The current values are retained.
•
Set all outputs to default: The default values resulting from the I/O
mapping are assigned.
•
Execute program: You can control the handling of the output values via a
program contained in the project, which DIADesigner-AX executes at
“STOP”. Enter the name of the program in the field on the right.
Always update variables
Global setting that defines whether or not DIADesigner-AX updates the I/O
variables in the bus cycle task. This setting is effective for I/O variables of the
slaves and modules only if ‘disabled’ is defined in their update settings.
•
Disabled (update only if used in a task): DIADesigner-AX updates the I/O
variables only if they are used in a task.
•
Enabled 1 (use bus cycle task if not used in another task ): DIADesigner-
AX updates the I/O variables in the bus cycle task if they are not used in any
other task.
•
Enabled 2 (always in bus cycle task ): DIADesigner-AX updates all
variables in each cycle of the bus cycle task, regardless of whether they are
used and whether they are mapped to an input or output channel.
