Digital I/O¶

SOMANET supports several Digital I/O which can be either used as SSI, I²C, BiSS or GPIO. Both differential as well as single-ended sensors are supported.

Detaiils and default settings can be found here for Servo Node EtherCAT.

How to configure Digital I/Os as Input or Output¶

All Digital I/Os are configurable as either input or output independently if they are used as general purpose input/output (GPIO). This is done in object 0x2210.

Subitems 1-4 describe the available pins and can be configured with these values:

0 Disabled (default)
1 Input without pull-down
2 Input active high - a pull-down resistor will be activated
3 Output
