LED panel and LED outputs
The LED panel is fully programmable through the Relay Configuration Tool (for an
example configuration, see Fig. 5.6.-2 ). Each LED has four states: ON, OFF, fast
blinking (2 Hz) and slow blinking (0.5Hz). The value field of each LED global
variable is 16 bit and the consecutive bit pairs (0 and 1, 2 and 3, and so on)
correspond to one LED state. The four states are illustrated in Fig. 5.6.-1 .
At power up, a test is run for the LED panel for its visual inspection. A testing
sequence can also be initiated via the global variable PSC_7_LEDTEST in the Relay
Configuration Tool.
