6.2.6. GPIOs (Hardware description)
Up to five opto-coupled GPIO pins [6] (General Purpose Input
Output) are available as additional digital control lines which can
be configured to be input or output (In/Out). This enables external
control and detection functions.
Configuration
Each GPIO can be defined as an input or output and combined
with either level (Hi/Lo active - non-latching) or edge (rising/falling
- latching) triggering.
A detailed description on how to configure the GPIOs and assign
the available software objects (Function) correspondingly is given
in Þ Chapter 12.5.4. "GPIOs (Configuration)" on page 55.
Note: When configuring a GPIO contact either as an input
(GPI) or as an output (GPO), observe the following:
▪ An external DC power supply is required.
▪ GPI: The corresponding pin is connected via an opto-
coupler with a serial resistance of 5.4 kΩ.
▪ GPO: The corresponding pin is connected to ground
(GND) via a relay (Low-Side-Switch).
Make sure the current per pin (GPO) does not exceed 1 A.
