“Station name”

The station name of the device. It is used for unique identification of the device in the network.

“Station status”

32-bit error code compliant with the PROFINET IO specification. In case of error, the status is provided here, for example, when establishing a connection fails or a link is interrupted. A description is also displayed.

“IP Parameters”

“IP address”

The IP settings of the device. Set when establishing the connection to the controller.

“Subnet mask”

“Default gateway”

“Communication Settings”

“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 I/O 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 packet is sent in each of the four phases of the send cycle and the load is distributed equally.

“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 IO Device does not receive I/O 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 IOspecification V2.3, only "0" is still permitted.

“RT class”

If available, you can select the required RT class from the list (real-time communication).

“User Parameters”

“Set All Default Values”

CODESYS resets all settings to default values (see default value column) from the GSDML file.

“Read All Values”

CODESYS reads the current values from the device and updates them in the editor.

“Write All Values”

CODESYS writes the current values from the editor to the IO device. Not all IO devices support parameter updates in run mode. If not, then an error message is displayed.
