The program uses 80 ms and 160 ms internal timers to implement four states,
with a combined period of 320 ms. The OSR instructions ensure that the SLC
executes the COP instruction only at the start of one of these states. The result
is that all four blocks are accessed within the 320 ms combined period of the
two timers.
6.6 Example: Using Flex I/O
When you configure the Flex I/O using COM PROFIBUS, always configure
18 slots, even if the slots are empty. The first two slots are used for status,
with the first slot configured as an input word and the second slot as an output
word. The remaining 16 slots are used for I/O modules. For each module,
configure two slots.
