4 LEDS
4.1 DIGITAL OUTPUT LED
LEDs O01 to O24 represent outputs DO1 to DO24, respectively.
In the MOD1, the LEDs of the digital outputs light RED whenever the digital output is active, Figure 5.2 on page 5-5 .
4.2 DIGITAL INPUT LED
LEDs I01 to I24 represent inputs DI1 to DI24, respectively.
The LEDs of the digital inputs are bicolor. They light RED if the digital input is activated through the positive of the
power supply, and the negative connected to the common of the inputs (PNP). They light GREEN if the positive
of the power supply is connected to the common of the inputs, and the negative of the power supply connected
to the respective input (NPN),
Figure 5.1 on page 5-3 .
4.3 RELAY OUTPUT LED
LEDs RL1 to RL6 of MOD7.00 represent, respectively, relays RL1 to RL6.
With the relays disabled, that is, with the NC contact closed and the NO contact open, the LEDs are off. When
a relay is enabled, that is, the NC contact opens and the NO contact closes, the LED representing this relay will
light GREEN; see
Figure 5.1 on page 5-3 .
