1 byte for data set 1 is available for every expansion module. The input values show the state
of the preliminary evaluation of the I/O module. This corresponds to the state of the element in
the controller module logic. The level at the associated terminal cannot be clearly detected
from this, as the data may be set to low, irrespectively of the level at the input terminal, by
means of the cross-connection detection or two-channel evaluation (e.g. I1-18).
When two-channel input elements have been configured for an I/O module, only the lower-
value bit represents the pre-evaluation state of the corresponding element (e.g. bit 0 for I1 and
I2, bit 2 for I3 and I4, bit 4 for I5 and I6, bit 6 for I7 and I8).
The higher-value bit (bit 1, 3, 5 and 7) is used as follows in this case:
0 = error, 1 = no error

Data from the PLC to the SP-COP2-ENI module
There are 5 output data blocks having 10 bytes each. These can be exclusively placed in each
corresponding slot 21 to 25.
The content of these data blocks can be used as input in the samosPLAN5+ logic editor or
forwarded to another network by a second gateway. Every bit to be used must be assigned a
tag name in order to provide the desired bits in the logic editor or for forwarding. Bits without
tag names are not available.
Detailed information about how you can assign and adapt the tag names of the input and out-
put data can be found here:
Software" manual, Section "Assigning tag names / changing display names (exercise)"
NOTICE
The standard value of the gateway data bit is zero following activation of the SP-COP2-ENI
device.
If the connection to PLC is terminated, then all of the gateway data bits in the samosPLAN5+
logic editor assume the value zero.
NOTICE
For output data with IOPS=Bad, all of the gateway data bits in the samosPLAN5+ logic editor
assume the value zero. This is the case, for example, if the PLC is stopped.
