Conditioning Monitoring CMM FC 247 Configuration

These blocks are chained.

If the module is configured to scan blocks in order, what is the effect of out of order blocks?
Specifically, is a phase lag possible if a chained block is a lower block number?
Should that be detected for optimum operation?

What would be the effect of a loop in the chaining where block 6554 is chained to block 6514, which is chained to block 6554? This is actually present in a configuration.
