Output channels on the myDatalogC3xx
Configuration section to configure the settings for the 2 relays on the myDatalogC3xx (i.e. on the data logger).
Configuration section "Output channels on the myDatalogC3xx"
| 1 | freely selectable designation for the output channels on the myDatalogC3xx | |
| 2 | Basic setting for the output channel | |
| off | Output channel deactivated | |
| digital | Digital output | |
| 3 | Inverts the level issued on the device |
| 4 | Setpoint (on/off) that should be issued
Note: If one of the check boxes "D1" or "D2" is selected in the
"Trigger" tab of the configuration section "Measurement channels on the myDatalogC3xx" or
"Internal channels on the myDatalogC3xx", the
"setpoint" entered is ignored for the corresponding output channel.

Switching state |
Initial situation: One of the measurement channels is to be used to determine the switching state at the ouput channel depending on the measurement value using the triggers. If one of the checkboxes "D1" (output channel "RELAY1" on the myDatalogC3xx) or "D2" (output channel "RELAY2" on the myDatalogC3xx) in the "Trigger" tab of the "Measurement channels" configuration section (see Measurement channels on the myDatalogC3xx) is selected for one of the measurement channels, the output channel is set to "off (Low)" at the time of the next measurement as long as the trigger for this measurement channel is not active.
Explanation: The output on the device is set to "off (Low)" up to the time of 2, as the measurement value on the measurement channel is below the trigger level. The trigger is active from the time of 2 which sets the output to "on (High)". At the time of 3, the output is ultimately set to "off (Low)" again as the measurement value falls below the "Level - hyst" value (100-5=95).
Ergänzung: If one of the two checkboxes ("D1" or "D2") has been selected, the "setpoint" entered for the relevant output channel via the interface is ignored. The parameter "invert" is however taken into account. If "invert" is active for the output channel, the switching states at the output are exactly the opposite of the example described above (i.e. with trigger active, the output channel is set to "on (High)").
