Application for I/O handling

Define here the application assigned to the device in the Devices tree that will be monitored for the I/O handling. For EcoStruxure Machine Expert, there is only one application available.

PLC settings area

Update IO while in stop

Note for PacDrive controllers: Supported by TM5 / TM7 IOs but not by controls or drive based IOs.

If this option is activated (default), the values of the input and output channels are updated when the controller is stopped. In case of expiration of the watchdog, the outputs are set to the defined default values.

Behaviour for outputs in Stop

From the selection list, choose one of the following options to define how the values at the output channels are handled in case of controller stop:

oKeep current values

The present values will not be modified.

oSet all outputs to default

The default values resulting from the mapping will be assigned.

oExecute program

You can determine the outputs behavior by a program available within the project. Enter the name of this program here and it will be executed when the controller gets stopped. Click the button ... to use the Input Assistant for this purpose.

Always update variables

Global definition, if the I/O variables are updated in the bus cycle task. This setting takes effect for the I/O variables of the slaves and modules only if their update setting is defined as Disabled.

oDisabled (update only if used in a task): The I/O variables are only updated if they are used in a task.

oEnabled 1 (use bus cycle task if not used in any task): The I/O variables are updated in the bus cycle task if not used in any other task.

oEnabled 2 (always in bus cycle task): All variables are updated in every cycle of bus cycle task, regardless of whether they are being used or whether they are mapped to an input or to an output channel.

You can set this option separately for each device in the I/O Mapping dialog.

Bus cycle options area

Bus cycle task

The selection list offers the tasks defined in the Task Configuration of the active application (for example, MAST). The default setting MAST is entered automatically.

<unspecified> means that the task is selected according to controller-internal settings, which are therefore controller-dependent.

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not set the Bus cycle task to <unspecified>, unless you understand the bus cycle task settings of the controller.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Generate force variables for IO mapping:

This setting is only available if supported by the device. Consult the Programming Guide specific to your controller for further information.

If the option is activated, for each I/O channel, which is assigned to a variable in the I/O Mapping dialog box, 2 global variables will be created as soon as the application is built. These variables can be used in an HMI visualization for forcing the I/O value. For further information, refer to the I/O Mapping chapter.

Enable diagnosis for device

The library CAA Device Diagnosis is added to the project automatically. For each device, a function block is generated in the Applications tree. If the function block already exists, an extended FB is used (for example, EtherCAT) or an additional function block instance is added. This function block contains the general implementation for the device diagnostics. By use of these function block instances, the status of the devices can be retrieved in the application. Furthermore, detected errors can be evaluated. The library also provides functions for the programmatical evaluation of the Devices tree (for example, search in child devices or jump to the parent device). For detailed information, see the PDF document CAA Device Diagnosis which is part of the library.

Show I/O warnings as errors

Warnings concerning the I/O configuration are dumped as detected errors.
