Fieldbus specific notes for parameterizing
Profinet
:
The parameter block can be written on Index 125 of the module using a Write Record access (SFB53).
A 4-byte header must be prepended to the parameter data: 0x1F, 0x00, 0x04, 0x18.
Profibus
:
The parameter block can be written on Index 125 of the module using a Write Record access
(SFB53). No header is required
.
EtherNet/IP
:
The parameter block can be written on class 0x65, instance = slot number, attribute 0x73 using
a writing accesses. No header is required. The parameter block can also be transferred as part of the
configuration assembly.
