EtherNet/IP Gateways - User Guide
24
Version EN-062020-1.00
The following table explains the columns of the EtherNet/IP mapping shown above.
Parameter
Meaning
Field Name
Name of the field
Field type
Data type of the field
Offset
Byte offset in the assembly
Device Name
Device type name as stated in the GSD file
Device Tag
Name specified in the PROFIBUS configuration web page
Slot
Slot number in which the module is plugged
Channel Id
Number of the PROFIBUS IO Channel starting with 1
Channel Name
Name of the PROFIBUS IO Channel
Channel Type
Data type of the PROFIBUS IO Channel
The field name is the identifier for the data that is mapped in this field. For the process data of the
configured PROFIBUS slaves the field names are generated using the name of the module and a four-level
address that is appended to the name.
The address is composed as
<segment>_<address>_<slot>_<iochannel>
, where:
<segment>
is the PROFIBUS segment (PA0, PA1, PA2, PA3 or DP)
<address>
is the PROFIBUS address of the slave
<slot>
is the slot number
<iochannel>
is the IO channel number (1 …)
Input Assembly
In addition to the input process data the first input assembly contains the following fields:
HaStatus
This field is reserved for future High Availability feature.
DeviceFailure
The DeviceFailure field represents a bit array with a fixed size of 8 bytes that indicates if an error
condition is present for the configured PROFIBUS slaves. Each bit in the bit array corresponds to one
slave. If an error condition is present on a slave, the value of the corresponding bit is 1. If not, the value
is 0. The concrete error is stated in the field
DeviceStatus
. The order of the configured PROFIBUS slaves
in the bit array is computed out of the segment they are connected to and their slave address. All slaves
of one segment are consecutively and are ordered from lowest to biggest address. The different
segments are ordered the following way PA0, PA1, PA2, PA3, DP.
