The following table indicates the I/O Assembly Data Attribute
mapping for Input Assemblies.
Instance 105: Allen-Bradley Drive Input Assembly with Parameters
160 SSC parameter values are used to form the Output_Data structure for this assembly. Parameters 111 and 112 contain numbers of the display
parameter values that form this assembly. A value of 0 in either parameter 111 or 112 means end of assembly. For example, a value of 0 in parameter 112
means that the assembly will only be six bytes long, with parameter 111 containing the parameter number of the parameter whose value is placed in word
3 of the assembly.
