7.8.5 Assembly attributes
The attributes of the output object (class 64h) and the input objects (class 65h) appear in
different combinations in the assembly object. 26 assembly instances can be used in pairs for
implicit communication, therefore there are 13 possible combinations. You can select these
combinations either via attribute 100 from instance 0 of the assembly object or by specifying
the combination on the PLC (Forward Open).
The following comparison shows the relationship between input and output instances: Input
instance = output instance + 50d.
A combination of the "heartbeat" and the ident status form the output instance 112 and input
instance 162. Refer to appendix B for a more detailed view of the object model.
7.8.6 Access administration
The assembly object is a collection of attributes from classes 64h and 65h (input and output).
Implicit or explicit access to these objects is possible (via the assembly object). Simultaneous
access is regulated to prevent the attributes from overwriting one another.
