Figure 56: RTD input shared by function blocks
GOOSE, RTD and binary inputs can be shared by multiple function blocks.

Online monitoring

Online monitoring enables the continuous monitoring of the signal or channel values
in the configuration. In the Online monitoring mode, the configuration cannot be
edited in the Application Configuration tool.
Online monitoring can be started by clicking the Work online button in the toolbar. If
the application configurations in the IED and PCM600 are the same, the online
monitoring starts. The online monitoring ends and the tool returns to the configuration
mode if the Work Offline button is clicked.
Online monitoring cannot be started if the application configurations
in IED and PCM600 are different.
In some cases when the function block input is directly mapped to the
function block output, the input is internally forced to the correct value
depending on the function block's settings. This function block design
is present in control blocks, setting group handling and tap changer.

Validation

Validation checks the application configuration for errors based on the rules that
govern the application creation at three different times.
• During the logic creation, while making a connection or placing a function block
• On demand by starting the validation
• When writing the application configuration to the protection relay
