Devices

This panel allows to enter the IP addresses and IED names. A second device can only be configured if the option redundant device is enabled.

Figure 1. Tab "Devices"

Primary device / Secondary device

IP address

Enter the IP address of the device ( IEC 61850 server) into the text field IP address.

For entering a port number other than the default (102), the format used must be <IP address>:<Port number>.

example

IP address with default port number: 192.168.1.150

IP address with port number 104: 192.168.1.150:104

IED name

Name of the respective IED.

Connect

Allows to enable/disable the connection to the respective IED (only when device redundancy is enabled).

Device switching

Health tag

Address string of the tag which contains the IED's health information. The tag can be selected with the Configure tag button.

The health state is generated by the respective IED. The allowed values can be defined by the user. The client monitors the state of the health tag in a configurable interval (see _IEC61850_IED.DeviceRedundancy.Config.HealthTagInterval). Depending on the user-defined logic, the information on the health tag can be used to trigger a switchover. The logic must decide if the appropriate value shall be written to _IEC61850_IED.DeviceRedundancy.Command.Switchover to trigger the switchover, or the connection to the IED shall be disabled when the IED's health status falls below a defined level.

The user application must consider WinCC OA redundancy. Depending on the connection state of the IEDs on either side, the active IED on WinCC OA host 1 might not be the same as the active IED on WinCC OA host 2.

Switch tag

Address string of the tag which contains the information for device switching. The tag can be selected with the Configure tag button.

The active IED writes TRUE, the passive IED writes FALSE to the address. The WinCC OA IEC 61850 client triggers a switchover when the tag of the active IED changes to FALSE and the tag of the passive IED changes to TRUE. The client monitors the state of the switch tag in a configurable interval (see _IEC61850_IED.DeviceRedundancy.Config.SwitchTagInterval).
