Device description

MA 258
i
Leuze electronic
Each participant in this network requires its own unique IP address, which must be assigned
to it via BootP or the control software. Alternatively, the DHCP procedure can be used.
The maximum length of a segment (connection from the hub to the last participant) is limited
to 100m.
Communication
The MA 258
i
gateway supports the CIP-based EtherNet/IP protocol and requires the setup
of a GENERIC module or the EDS file (
E
lectronic
D
ata
S
heet), depending on the control soft-
ware used, for communication.
Notice!
Rockwell RSLogix 5000 supports EDS integration for EIP from software version 20.00 and
up.
The EDS file is available for download from the Leuze home page.
The EDS file is named "MA258i.eds"; the corresponding icon is named "MA258i.ico".
The EDS file includes all communication parameters of the participants as well as the
available objects.
The input/output data is addressed according to the following fundamental scheme:
1.
Device address (MAC ID)
The participant is addressed with its MAC ID, which is unique in the network.
2.
Object class identifier (class)
Used as the basis for addressing the desired object class.
3.
Object instance identifier (instance)
Addressing of the object instance within the object class.
4.
Attribute identifier (attribute)
Addressing of the attribute within the object instance.
5.
Service code (get, set, reset, start, stop and others...)
The maintenance code ultimately describes the type of access to the data, e.g.,
reading or writing.
