Alarm value (r2124, interpret decimal):
0: general consistency error
1: error in the IP configuration (IP address, subnet mask or standard gateway).
2: Error in the station names.
3: DHCP was not able to be activated, as a cyclic PROFINET connection already exists.
4: a cyclic PROFINET connection is not possible as DHCP is activated.
Note:
DHCP: Dynamic Host Configuration Protocol
See also: p8920 (PN Name of Station), p8921 (PN IP address), p8922 (PN Def Gateway), p8923 (PN Subnet Mask),
p8924 (PN DHCP Mode)
Remedy: - check the required interface configuration (p8920 and following), correct if necessary, and activate (p8925).
or
- Reconfigure the station via the "Edit Ethernet node" screen form (e.g. with STARTER commissioning software).

A50011 (F) Ethernet/IP: configuration error
Message class: Communication error to the higher-level control system (9)
Reaction: NONE
Acknowledge: NONE
Cause: An EtherNet/IP controller attempts to establish a connection using an incorrect configuring telegram.
The telegram length set in the controller does not match the parameterization in the drive device.
Remedy: Check the set telegram length.
For p0922 not equal to 999, then the length of the selected telegram applies.
For p0922 = 999, the maximum interconnected PZD (r2067) applies.

A50020 (F) PROFINET: Second controller missing
Message class: Communication error to the higher-level control system (9)
Reaction: NONE
Acknowledge: NONE
Cause: The PROFINET function "Shared Device" has been activated (p8929 = 2). However, only the connection to a
PROFINET controller is present.
Remedy: Check the configuration of the PROFINET controllers as well as the p8929 setting.
F50510 FBLOCKS: Logon of the run-time group rejected
Message class: General drive fault (19)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: When the run-time groups of the free function blocks attempted to log on with the sampling time management, the
logon of at least one run-time group was rejected.
Too many different hardware sampling times may have been assigned to the free function blocks.
Remedy: - check number of available hardware sampling times (T_sample < 8 ms) (r7903).
F50511 FBLOCKS: Memory no longer available for free function blocks
Message class: General drive fault (19)
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: When the free function blocks were activated, more memory was requested than was available on the Control Unit.
Remedy: Not necessary.
A50513 (F) FBLOCKS: Run sequence value already assigned
Message class: General drive fault (19)
Reaction: NONE
Acknowledge: NONE
Cause: An attempt was made to assign a run sequence value already assigned to a function block on this drive object to
another additional function block on the same drive object. A run sequence value can only be precisely assigned to
one function block on one drive object.
