Digital Input/Output
Basic QML201 Logger
In addition to digital frequency/counter inputs (2 + 1 pcs), analog
inputs can be used for monitoring digital state. Furthermore, the state
status information can be used for controlling one of the excitation
voltages, e.g. as a contact enclosure that can be activated by an event.
Optional QMI108 Digital I/O Module
The digital inputs and outputs of QMD108 are freely and individually
configurable by the user.
Hardware Setup View: Digital I/O Configuration
The Hardware Setup view also provides the possibility to select
which outputs are controlled by Timers. The on/off cycle for the
selected outputs can then be configured in the Timers view. The other
possibility to control the outputs is to use alarms, for example, to
activate the output signal when the alarm condition is met. The alarm
condition is configured in the Alarms view.
The following template shows an example of the Timers view. In the
example the configuration is as follows:
- Output 0 toggles between on and off in a one minute cycle.
- Output 5 is on for one minute before each full hour.
