The module's SNMP agent transmits events (traps) to the Manager. The managed traps systems are as follows:
Coldstart Trap:
On the BMX NOE 01x0 modules and on the Ethernet port of the BMX P34 20x0 CPUs, the event is transmitted following a module supply Reset, a processor Reset, or the downloading of an application to the PLC.
Authentication Failure Trap: event transmitted following an authentication problem. The Community Name field in the received message is different to the one configured on the module. This trap can be enabled during module configuration.
