2.4.3
Exceeding the permissible current consumption at the external I/O
interface
In order to avoid damage to your device due to excessive current
consumption at the external IO interface, you must observe the following
instructions. These apply to all devices described in this manual.
·
When operating the NANL-B500G-RE device, the prescribed device-
specific maximum values for the current consumption at the I/O signal
pins of the external I/O interface must not be exceeded.
·
The netX chip and other components of the NANL-B500G-RE device
can be damaged if the current consumption at the I/O signal pins of the
external I/O interface exceeds the maximum permitted values!
The information on the maximum current consumption at the I/O
signal pins for the device described in this manual can be found in
section
Maximum permissible current consumption (external I/O
2.4.4
Damage of externally attached hardware
NANL-B500G-RE
·
If the +3.3V output of the external IO interface is enabled (I/O status
LED lights up orange), externally attached hardware could be damaged
as voltage is driven.
·
If the +24V output of the external IO interface is enabled (I/O status LED
lights up red), externally attached hardware could be damaged as
voltage is driven.
Note on USB handling in autonomous operating mode:
The .nsprj
configuration is applied immediately when the USB memory device is
connected. This means that the GPIO configuration is also applied. It is
therefore important to ensure that switching GPIO, e.g. to the 24 V output,
does not damage any externally connected circuit.
·
Before an external device is connected to the NANL B500G device,
check whether the value for the voltage for the NANL B500G device set
in the software is correct. Furthermore, check whether the external
device is suitable for the application.
