6. Redundancy with NX3030 CPU

Table 6-8. NETB Interface Specific Diagnostics
The “sNET_Stat” substructure has service success and failure statistics. The local and remote PLCs
statistics can be restarted through commands:
//Local PLC
DG_NX4010.tRedundancy.RedCmdLoc.bResetNETStatisticsLocal := TRUE;
//Remote PLC
DG_NX4010.tRedundancy.RedCmdLoc.bResetNETStatisticsRemote := TRUE;
The substructure has the following counters:

bFailedPBUS3A
TRUE – This PLC can’t communicate in
the master state (active or passive) in the
PROFIBUS 3 A network. The master mode
(communicating with slaves) is assumed
by the Active PLC. The passive mode
(communicating with the active master) is
assumed by the Non-Active PLC. This
failure can also be indicated in case the
NX5001 module has a microprocessor
failure, or in case it can’t communicate with
the NX3030 CPU via bus.
FALSE – There aren’t failures in the
PROFIBUS 3 A network.

bFailedPBUS3B
TRUE – This PLC can’t communicate in
the master state (active or passive) in the
PROFIBUS 3 B network. The master mode
(communicating with slaves) is assumed
by the Active PLC. The passive mode
(communicating with the active master) is
assumed by the Non-Active PLC. This
failure can also be indicated in case the
NX5001 module has a microprocessor
failure, or in case it can’t communicate with
the NX3030 CPU via.
FALSE – There aren’t failures in the
PROFIBUS 3 B network.
