Software channels
Realise and execute monitoring and automation tasks easily
The Delphin measuring and testing devices have extended functions that are summarised under the term software channels. The online measurement data is calculated with the software channels and then used for visualisation, storage or control.
In this way, entire programme sequences can be configured very simply and intuitively with the regulation and control function. These then run autonomously without PC support. This is how you use your data logger effectively, also as a monitoring device or PLC replacement.
The software channels enable functions such as limit value monitoring, integration or online calculation and are configured very easily. This means that even users who are not experts in programming can easily implement their own monitoring tasks or balancing independently in the unit.
