Function description: Digital inputs/outputs

4.3.2 Digital outputs (24 V)

4.4 Digital outputs

By default, the digital channels of the MSX-E1701 are configured as inputs.
In order to convert a port, i. e. a pair of channels into an output, the configuration has to be changed
on the web interface of the MSX-E system (see Chapter 6.1.1) or by the SOAP function
"int MSXE170x__DigitalIOInitPortConfiguration()".

IMPORTANT!
For each connector or port, only inputs or outputs can be configured.
The ports configured as outputs are high-impedance. The status of the outputs can be read back by
way of control.
If a short-circuit occurs at a connected output, this output will be deactivated.
As soon as the short-circuit has been eliminated, a rearm has to be carried out to reactivate the output
(see Chapter 6.1.1). This means that the output is set to the status value that was programmed before
the short-circuit occurred. A new value can only be defined after the rearm event.
