REX640 Engineering Manual

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.

Note: Online monitoring cannot be started if the application configurations in IED and PCM600 are different.
Note: 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.
