The 3RW5 communication module supports the following interrupts:
• Diagnostic interrupt (error interrupt)
• Diagnostics interrupt (maintenance interrupt)
• Removal and insertion interrupt (3RW5 HMI High Feature)
7.2.1
Triggering of a diagnostics interrupt (error interrupt)
In the case of a coming or going event, with appropriate parameterization (Page 79), the
3RW5 soft starter triggers a diagnostic interrupt (error interrupt). The "ER" LED on the 3RW5 soft
starter flashes red in this case.
The CPU of the controller then interrupts processing of the user program and processes the
diagnostics interrupt OB (OB 82). The interrupt triggering event is logged in the start
information of the diagnostic interrupt OB. Depending on the model, the controller switches to
the "STOP" operating state if the diagnostics interrupt OB is not available.
7.2.2
Triggering of a diagnostics interrupt (maintenance interrupt)
The aim of maintenance interrupts is to enable early detection and correction of potential faults.
In the case of a coming or going event, with appropriate parameterization (Page 79), the
3RW5 soft starter triggers a diagnostic interrupt (maintenance interrupt). The LED "MT" on
the 3RW5 soft starter lights up yellow in this case.
The CPU of the controller then interrupts processing of the user program and processes the
diagnostics interrupt OB (OB 82). The interrupt triggering event is logged in the start
information of the diagnostic interrupt OB. Depending on the model, the controller switches to
the "STOP" operating state if the diagnostics interrupt OB is not available.
7.2.3
Triggering a PROFIenergy status interrupt
If the status of the PROFIenergy energy saving function changes (energy saving mode or
operating mode), the 3RW55 or 3RW55 Failsafe soft starter triggers a status interrupt. The LED
"MT" on the 3RW55 or 3RW55 Failsafe soft starter flashes yellow when energy saving mode is
active.
Note the information in chapter PROFIenergy (Page 83).
