Signal Matrix Tool (SMT)

The SMT connects the virtual IO to the physical IO. This offers high flexibility

without the need to adjust the configuration. When a configuration has been

completed with the Application configuration tool CAP 531, the Signal Matrix

tool can be opened. This is done from the PCM 600 menu that appears when the

right mouse button is clicked on the IED symbol in the system project structure.

Changes made in the IED since the last compilation are shown at initiation.

Connect your IO. The configuration has an appropriately chosen default IO

arrangement but the tripping signals are connected to the physical IO supplied

as basic supply. Alarm signals and the like must be configured per application.

Figure 9: The Signal Matrix Tool

Analog signals can be connected to separate CT cores, VT fuses and so on but

different protection functions may also be connected to the same analog chan-

nels according to user preferences and the availability of analog channels.

Download the signal matrix. Changes such as reconfiguration of the analog

supply will require a full restart of the IED. Simple output signal changes on the

other hand can be executed quickly. Proceed with testing, or if settings first

need to be adjusted refer to the next section before starting tests.
