Assembly Instance 37 = 0x25
Assembly instance 37 belongs to the device profile
discrete universal I/O device.
It contains output
data (O
→
T) with a scope of up to 50 bytes.
Assembly instance 37 corresponds to
input data block 1 to 5
of the logic data of the SP-COP2-ENI
module with a total scope of 50 bytes.

Assembly Instances 138 = 0x8a to 141 = 0x8d
Assembly instances 138 to 141 are provided to make more than one output data connection availab-
le. In Class 1 connections, output data from the PLC to the controller module can only be sent using
“Exclusive Owner” rights. If, for example, a PLC “possesses” the assembly instance 138, then it “pos-
sesses” the output bytes 10 to 49. By contrast, output bytes 0 to 9 are freely available and can be
used by another PLC (O
→
T).
In a further example, the first PLC “possesses” 10 output bytes of the assembly instance 37, whilst
the second PLC “possesses” 10 output bytes of assembly instance 138 and the third assembly in-
stance 139 with 30 output bytes. Here, three PLCs possess “Exclusive Owner” connections with out-
put data. In total, up to five PLCs can share the output data range, each with 10 bytes.
Assembly instance 138 comprises data with a scope of up to 40 bytes, assembly instance 139 com-
prises data with a scope of up to 30 bytes, assembly instance 140 comprises data with a scope of up
to 20 bytes and assembly instance 141 comprises data with a scope of up to 10 bytes.
The first byte of assembly instance 138 is the eleventh byte of the logic data of the SP-COP2-ENI mo-
dule. In samosPLAN
6, it has the designation
input data block 2
. The first byte of assembly instance
139 is 21. Byte of the logic data of module SP-COP2-ENI. In samosPLAN
6, it has the designation
in-
put data block 3
. The first byte of assembly instance 140 is 31. Byte of the logic data of module SP-
COP2-ENI. In samosPLAN
6, it has the designation
input data block 4
. The first byte of assembly in-
