Controller – Overview

Object: PROFINET Controller

This tab shows an overview of all devices with their communication settings. The station name, the IP configuration, as well as the transfer speed of all devices configured for this PROFINET Controller can be centrally managed in the list. (Multiple selection is possible.)

Default IP

Sets the IP address of the selected device to a value within the standard address range. This range is defined in the settings of the controller.

The command is also available in the context menu of the selected line.

I/O Performance

Opens the Communication Settings dialog. Here is where the transmission speed for I/O data is configured for all selected devices. For individual parameters (RT class, Send clock, Reduction ratio), a value range can be selected that is valid for all selected devices.

The command is also available in the context menu of the selected line.

Table 9. Communication Settings Dialog

Send clock (ms)	Send clock (in milliseconds).
Reduction ratio	Scaling factor The send cycle is defined by Send clock * Reduction ratio. Therefore, a Send clock of 1ms and a Reduction ratio of 4 means that IO data is sent every 4ms.
Phase	With a Reduction ratio of `n`, the send cycle is divided into phases 1 to n (where data is sent in one phase only). You can determine in which phase the data is sent for the purpose of load distribution. If Send clock = 1 and Reduction ratio = 4 (as in the example above), then you could configure phases 1–4. For four slaves with this send clock and reduction ratio settings, you could assign one of the four phases to each of the four slaves. In this way, only one data package is sent in each of the four phases of the send cycle and the load is distributed equally. If no phase is configured, then the controller selects the phase under consideration of equal distribution of load (Ethernet frames / PLC cycle).
Watchdog (ms)	Monitoring time. A multiple of the send cycle (send cycle = Send Clock * Reduction Ratio). Possible values: 3 ms – 1920 ms. A connection is terminated when the controller or the PROFINET Device does not receive IO data from the communication peer within this time period. The device enters failure mode and switches the outputs to substitute values.
VLAN ID	VLAN identifier: Number between 0 and 4095 for VLAN type 802.1Q. Note: For newer devices compliant with PROFINET specification V2.3, only "0" is still permitted.
RT class	If available, you can select the required RT class from the list (real-time communication).
