'Settings' Editor (Profinet Controller)

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

This help topic describes the 'Settings' editor of the 'Profinet' PLANT node (which represents the Profinet Controller). On the left side on the 'Settings' page, several editor categories can be selected. These are described below in detail.

This topic contains the following sections:

'All'

After selecting the 'All' category, the settings that are available in each category are visible on one page.

'Profinet Controller'

Parameter Description

Vendor ID Indicates the ID of the device manufacturer.

Device ID Indicates the ID of the device.

Number of connectable Profinet devices Indicates how many Profinet devices can be connected to the controller. The maximum number of table rows in the 'Device List' editor corresponds to this number.

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

Multiple interface mode The parameter can only be edited if the Profinet Controller supports the Multiple Interface Mode.
If selected, the Multiple Interface Mode is activated for the Profinet Controller.
Using this mode, Profinet devices with more than one interface can be run with double redundancy (two separate interfaces which are separately connected to redundant controllers).
The multiple interface mode is only possible if the Profinet Controller as well as all devices involved support this mode (even if they themselves have only one interface).
Read the topic "Multiple Interface Mode" for details.

'Update tasks'

The interval at which variables are updated from the running controller can be configured by selecting update tasks.

Parameter Description

IO Controller system and global variables Drop-down list for selecting the task with which the system variables (PNIO_* ) and assigned global input/output variables of the Profinet I/O controller are updated. Observe the note below.

IO Device system variables Drop-down list for selecting the task with which the system variables (PND_S?_*) of the Profinet I/O devices are updated (that is to say, when the global input/output variables connected to the process data items are read/written). Observe the note below.

Parameter	Description
IO Controller system and global variables	Drop-down list for selecting the task with which the system variables (PNIO_* ) and assigned global input/output variables of the Profinet I/O controller are updated. Observe the note below.
IO Device system variables	Drop-down list for selecting the task with which the system variables (PND_S?_*) of the Profinet I/O devices are updated (that is to say, when the global input/output variables connected to the process data items are read/written). Observe the note below.

The drop-down lists provide the suitable tasks for selection that are defined in the 'Tasks and Events' editor (on the 'PLCnext' PLANT node). Depending on the controller used, different settings concerning update tasks may be possible.

Note
If no task is selected here, the update is done in an interval of 50 ms.

'Profile'

The page displays the profile version of the Profinet Controller.

'Fast Start Up'

In a Profinet network, the Fast Start Up (FSU) function is used to minimize the startup time of a Profinet device and to power up the device quickly.

Parameter Description

DCP hello supported If selected, FSU is activated.
With enabled FSU, the I/O device sends a DCP (Discovery and Configuration Protocol) hello frame to the Profinet controller as soon as power on is completed. When the controller has received the frame, it establishes the connection to the I/O device.

Parameter	Description
DCP hello supported	If selected, FSU is activated. With enabled FSU, the I/O device sends a DCP (Discovery and Configuration Protocol) hello frame to the Profinet controller as soon as power on is completed. When the controller has received the frame, it establishes the connection to the I/O device.

Further Info
Read the topic "Configuring Fast Start Up (FSU) for Profinet I/O" for details and procedures how to configure FSU for I/O device as well as the port settings on the I/O device.

'SNMP Adjust'

Note
This category is device-dependent and read from the device description / GSDML file.

This category is used to adjust the Simple Network Management Protocol (SNMP) access for the Profinet I/O controller (master) and the underlaid devices. If the 'Global SNMP configuration' checkbox is activated, the values from the Profinet master configured in this category are used for the entire Profinet I/O system (all underlaid Profinet submodule interfaces). The 'SNMP Adjust' category is not visible for any of the underlaid submodule interfaces. If the checkbox is deactivated, the 'SNMP Adjust' category is available for each underlaid submodule interface and can be specified individually.

The settings made here are later written as startup parameters to the device.

To adjust the SNMP access for the Profinet master and all underlaid devices, activate the 'Global SNMP Configuration' checkbox and configure the SNMP parameters as described in the topic "Configuring SNMP in the Profinet Network" (the parameters will become visible when the checkbox is activated).
