Vendor Object
1127370635
The Vendor Object with class ID = 0x78 provides CRC, status and diagnostic data which are
not covered by device profile
General Purpose Discrete I/O Device
. Furthermore it supplies
an interface to input and output data in a compressed and therefore network traffic saving
format.
Note that several instances have different attribute types and numbers. Packing several data
together into this vendor object class is made for legacy reasons.
1127372171
Instance 1
Instance 1, attributes 1 to 50, supply input bytes configured by the
in sa-
mosPLAN5+. This is data transferred by the logic of the controller module to the PLC.
1127373707
Instance 2
Instance 2, attribute 1, supplies the CRC of the active project file created by samosPLAN5+.
Instance 2, attributes 2 to 8 are reserved for future applications.
1127375243
Instance 3
Instance 3, attributes 1 to 60 make state bytes available. The descriptions for each bit are listed
in the table
State bytes of the controller module SP-COP2 [ch. 8.4.8.7, p. 99]
. This data corres-
ponds to
, which is described at various points in this document.
A value = 1 for bits in instance 3, attributes 1 to 60, stands for “OK”/”Not used”/”Reserved”. A
value = 0 stands for “Fault” or “Error” or “Outside the limit”. “Doesn’t matter” means that the
value can be equal to 0 or 1.
"EA module at Pos. n" with n = 1 .. 12 stands for the first to twelfth safe or unsafe expansion
module.

Instance 4
The instance 4, attributes 1 to 60 are reserved for future use. Values are zero and changes are
reserved.
1127377803
Instance 5
Attribute 1 of instance 5 makes the system state/mode of the controller module available. The
values are listed in the following table:
