7.2 Addressing, registers and axis status flags
The SPC200 knows different operators, variables and flags
which can be used in the program for controlling a position
ing sequence.
A distinction is made between 1−bit, integer and real vari
ables; between remanent and non−remanent variables.
All the inputs and outputs of the SPC200 are treated like 1−bit
variables.
