'Interface List' Editor (Profinet Controller)

The following information refers to a specific, typical device type. Your screen may differ.

This help topic describes the 'Interface List' editor of the 'Profinet' PLANT node (which represents the Profinet Controller). This tabular editor contains (the interfaces of) all Profinet devices which have been scanned or added under the 'Profinet' node.

The editor enables access to various Profinet device parameters, for example, the 'Function' and 'Location' definition, RT class, reduction ratio, and monitor factor. Some parameters, such as update time and monitor time are read-only. The editor allows to read parameter values from and write the editable values to the device.

The values set in the 'Interface List' editor are synchronized with the 'Interface' editor of each Profinet device.

Column Description

# Number of the Profinet device in the network.

Name Name of the Profinet device including its entire device instance path in the project.

Function Function description appropriate to the Profinet specification. The parameter is still available after a firmware update.
The 'Function' text is shown in the device node name (preceding the type) in the PLANT.
Max. string length: 32 characters

Location Installation location of a device appropriate to the Profinet specification. The parameter is still available after a firmware update.
If no 'Function' is specified, the 'Location' text is visible in the tree.
Max. string length: 32 characters

RT class Indicates or sets the Realtime class of the Profinet Controller:
RT = RealTime, IRT = Isochronous RealTime.
The parameter can only be edited if the Profinet device supports more than one RT class.
The RT class set for connected Profinet devices must match the realtime mode set for and supported by the Profinet Controller. Otherwise, a Profinet error (for example, PNIO0011) is reported and the Profinet communication with the affected device cannot be established.

Timing With 'Symmetric' timing, the related input and output parameters always have the same value. With 'Asymmetric' timing, the related input and output parameters can have different values.
Example: If 'Symmetric' is selected and you set the 'Reduction ratio (inputs)' value to 16, the same value is also automatically used for the 'Reduction ratio (outputs)' value (and vice versa). If 'Asymmetric' is selected, you can enter different values for the two parameters.

Reduction ratio (inputs) The time in which the inputs of the Profinet device are updated (can be set individually for each Profinet device for each data direction).

Update time (inputs) Update time of the I/O data between Profinet controller and device.

Monitor factor (inputs) Multiplier of the 'Update time (inputs)' for aborting the connection if no data is exchanged.
Monitor factor x update time = monitor time.
Value must be a multiple of 3.

Monitor time (inputs) Product of the 'Update time (inputs)' and the 'Monitor factor (inputs)'. (Value cannot be set directly.)
Period during which the Profinet controller waits for data from the Profinet device. If the Profinet device does not send data to the Profinet controller within this period, the connection between the Profinet controller and the Profinet device is terminated.

Reduction ratio (outputs) The time in which the outputs of the Profinet device are updated (can be set individually for each Profinet device for each data direction).

Update time (outputs) Update time of the I/O data between Profinet controller and device.

Monitor factor (outputs) Multiplier of the 'Update time (outputs)' for aborting the connection if no data is exchanged.
Monitor factor x update time = monitor time.
Value must be a multiple of 3.

Monitor time (outputs) Product of the 'Update time (outputs)' and the 'Monitor factor (outputs)'. (Value cannot be set directly.)
Time that decides how long the Profinet devices cannot receive valid Profinet telegrams before substitute values are written to the outputs. This setting can be used to influence the error insensitivity of the network.
