Return codes for parameter setting via explicit messages
The Ethernet Industrial Protocol (EtherNet/IP)
Timeout of the
explicit mes-
sages
The timeout is triggered by the DHR41B option. The timeout interval must be set by the
master after the connection has been established. The EtherNet/IP specification refers
to an "Expected packet rate" rather than a timeout interval in this case. The expected
packet rate is calculated from the timeout delay as follows:
t
Timeout_ExplicitMessages
= 4
×
t
Expected_Packet_Rate_ExplicitMessages
It can be set using connection object class 5, instance 1, attribute 9. The range of values
runs from 0 ms to 655535 ms in 5 ms steps.
If there is a timeout for the explicit messages, this connection type is automatically
dropped for the explicit messages. This is the default setting for EtherNet/IP. The con-
nection for these explicit messages must be re-established to communicate with these
messages again. The timeout is
not
forwarded to the IEC program.

04
Path segment error
The processing node cannot interpret the 'Path segment iden-
tifier' or the segment syntax.
05
Path destination unknown The 'Path' refers to an object class, object instance or a struc-
tural element that is not supported by the processing node.

The selected object cannot perform the service in its current
status.
0D
Reserved
0E
Attribute not settable
It is not possible to access the selected object for writing.
10
Device state conflict
The current status of the device makes it impossible to per-
form the required service.
11 - 12
Reserved
13
Not enough data
The length of the transferred data is too short for the service
to be performed.
14
Attribute not supported
The selected attribute is not supported.
15
Too much data
The length of the transferred data is too long for the service to
be performed.
16
Object does not exist
The selected object is not implemented in the device.
