Monitoring 24V load circuits using SITOP PSE200U with single channel message and SIMOTION CPU

  • Entry
  • Associated product(s)

Task
Using the SITOP PSE200U selectivity module with single channel message enables you to monitor up to four 24V load circuits for overload or short-circuit. The signal at the state output (S) of the SITOP PSE200U module provides you with serially coded information on the state of the individual load circuits connected to outputs OUT 1 to OUT 4 of the SITOP PSE200U selectivity module. The state of the load circuits shall be detected by a SIMOTION CPU and monitored.

Solution
The entry on hand contains a function block as well as a function description. The function block enables you to read and evaluate the signal of the status output (S) via a digital input at the SIMOTION CPU. A possible application, for example, would be indicating this information as alarm message on a panel.

The figure below shows the graphic representation of the solution.
