Possible error causes and remedies
Error cause 3.2
The NCU has an IP address that does not match the network or has an invalid IP address.
The NCU participates in DHCP operation and the NCU is an active DHCP/DNS server
(either as a result of the DHCP SyncMode ON_MASTER or as a result of the Sync priority -
just the same as the other server candidates and random selection). The NCU is set with an
incorrect IP address and an incorrect IP range for the IP addresses that can be dynamically
allocated. The NCU possibly changed from DHCP standby to active server as the computer
with DHCP MASTER has failed/has been switched-off.
Remedy 3.2
The same as for remedy 3.1
Error cause 3.3
The NCU has an IP address that does not match the network or has an invalid IP address.
The NCU participates in DHCP operation and operates with the incorrect IP address. After
the NCU booted, an additional component that is already operational (NCU or PCU) with
active DHCP server was connected to the network. An additional active DHCP server was
switched into the system network while operational; this active DNCP server has an
incorrect address range. This is a configuration error.
Remedy 3.3
The same as for remedy 3.1
Error cause 4.1
The NCU has a valid IP address in the system network, however, not the required IP
address.
The NCU does not participate in DHCP operation and operates with a permanently set
target address that is different from that saved in MMC.INI in the system network - however,
this is a valid address. This is a configuration error.
Remedy 4.1
Connect the service PG to the NCU via X127. Log into Linux via WinSCP or Putty.
If the set NCU mode (no DHCP) is to be kept, the fixed IP address of the NCU must be
changed.
Correctly enter the following entries into the file /user/system/etc/basesys.ini
[InternalInterface]
; With InternalIP and InternalNetMask (both must be set together),
; you can change the address on the internal/TCU/automation/system net.
InternalIP=192.168.214.1
InternalNetMask=255.255.255.0
Then restart the NCU.
Error cause 4.2
The NCU has a valid IP address in the system network, however, not the required IP
address.
The NCU does not participate in DHCP operation and operates with a permanently set
target address that is different from that saved in MMC.INI in the system network - however,
this is a valid address. This is a configuration error.
Remedy 4.2
The same as for remedy 4.1
Error cause 4.3
