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
available. 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 in-
stance 138, then it "possesses" 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 as-
sembly instance 139 with 30 output bytes. Here, three PLCs possess "Exclusive Owner"
connections with output 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
comprises 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 module. In samosPLAN5+, it has the designation input data block 2. The first byte of as-
sembly instance 139 is 21. Byte of the logic data of module SP-COP2-ENI. In samosPLAN5+, it
has the designation input data block 3. The first byte of assembly instance 140 is 31. Byte of
the logic data of module SP-COP2-ENI. In samosPLAN5+, it has the designation input data
block 4. The first byte of assembly instance 141 is 41. Byte of the logic data of module SP-
COP2-ENI. In samosPLAN5+, it has the designation input data block 5.
Write requests are refused if the assembly is already used by an active I/O connection.
