ETAS Digital Output Channels ("DO" Connection)
ES930.1 - User Guide 55
9.1.8 Synchronous Groups and update Mode
The update mode can be configured independently for every digital output
channel. The output signals of the digital channels can optionally be updated
either asynchronously (for each channel) or synchronously. For synchronous
operation, the digital channel is assigned either to the synchronous group A,
synchronous group B or synchronous group C. All channels of a synchronous
group are updated together.
9.1.9 LED Control
With the LED Control assembly. the output signal of the channel can be
released for the LED control unit, where it can be assigned either to the LED
U1
or the LED U2 .
9.1.10 LEDs U1 and U2
The user can assign the LEDs U1 and U2 to two random digital output channels
("DO 1" to is "DO 6") in the application software. The LED lights if the state of the
signal of the assigned digital output channel is active.
It is not possible to assign one LED to different digital output channels at the
same time.
9.1.11 Electrical Isolation
The digital output channels "DO 1" to "DO 6" are not electrically isolated against
each other. The digital output channels are electrically isolated together as
channel group to the supply voltage and as channel group to the housing of the
module.
NOTE
The release or blocking of the output signal in the Power Stage Control
assembly affects only the control of a Half-bridge, not the digital output signal
of the channel at the "DO n" connection.
