Vendor Object
80306315
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 inter-
face 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 toge-
ther into this vendor object class is made for legacy reasons.
80315659
Instance 1
Instance 1, attributes 1 to 50, supply input bytes configured by the
output data set 1
in samos-
PLAN
6. This is data transferred by the logic of the controller module to the PLC.
80328203
Instance 2
Instance 2, attribute 1, supplies the CRC of the active project file created by samosPLAN
6. Instance
2, attributes 2 to 8 are reserved for future applications.
80338443
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. 96]
. This data corresponds to
data set 3
, 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 reser-
ved.
80364171
Instance 5
Attribute 1 of instance 5 makes the system state/mode of the controller module available. The valu-
es are listed in the following table:

Instance 6
Attribute 1 of instance 6 makes the error code of the most recent error of the controller module
available. A value = 0 means that no error has occurred. Attribute 2 supplies the error code of the
previous error, etc., up to and including attribute 5.
