Digital outputs
By default, the digital channels of the
MSX-E1516
are configured as inputs.
A port, i.e. a pair of channels can be configured as an output via the web interface of the MSX-E
system (see Chapter 4.1.1) or via the SOAP or Modbus function “DigitalIOInitPortConfiguration”.
NOTICE!
For each connector or port, only inputs or outputs can be
configured. In the event of a system reboot, the configuration is
only persistent if it has been changed on the web interface.
A port configured as an output is 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 4.1.1). 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.
