Measurement and evaluation of the ambient conditions in the control cabinet Recording ambient conditions Recording operating hours and power-on cycles Saving user data directly on the module Supports blackout mode The module is designed for measuring ambient conditions in the control cabinet as well as recording operating hours and power-on cycles. In addition, the module offers the option of storing user data directly on the module and supports blackout mode. Measuring and evaluating ambient conditions The ambient conditions are continuously evaluated by the module. The duration in which individual parameters are within certain ranges is stored internally. This makes it possible, for example, to determine how long the system remained in a certain temperature range. The histograms recorded by the module can be read out by the user. Internal module memory for user data With 512 kB nonvolatile user memory (flash), data from the application can be saved directly on the module and also read back from the module. The data is therefore retained after the module or CPU is restarted and remains with the module in the event that the module is connected to another machine or system, for example. Data retention is maintenance-free – without batteries. Blackout mode The integrated blackout mode ensures that module functionality is maintained even in the event of network failure.
