Diagnostic Data
Alarms from the NRG bus chain are passed as an event driven acyclic command via the PROFINET Diagnostic System.
Alarms are generated from both the NRG controller as well as each NRG solid state relay on the bus chain. The
diagnostic type used for al alarm is the channel diagnosis (USI = 0x8000). Alarms are identified using the slot / subslot
configuration of the NRG bus chain.

PROFINET Pull / Plug Alarms
In PROFINET, Pull and Plug Alarms occur when modular devices are disconnected (pulled)/ connected (plugged).
Whenever a plug event occurs, the module in question is reparametrized automatically by PLC. These are standard
PROFINET alarms that do not fall under the channel diagnostics.
In the case of the NRG a Pull alarm shall indicate that an RG..N has stopped responding on the chain. When the device
recovers from a Pull either by reconnection or a recovery from a crash, the Plug alarm shall be triggered.
Note
: It is not possible to plug new RG..Ns during runtime.
