[Adding To Current Routine VS Creating New Routine]

Hi all,

Has anyone seen any documentation or have any insight into what overhead is added by creating a new routine versus adding logic to an existing one?

I.E what are the pro's and con's of splitting a monster routine into several smaller ones?

Many thanks in advance.

[PLC to PLC Comms via Generic Ethernet Module]

Is it possible to add another AB Rockwell PLC to the network tree as a Generic Ethernet Module and use it as IO?

Any idea where I would find information regarding assembly instance and size of I/O/C for AB Rockwell products?

If possible, what are the pros and cons when compared to produce/consume and MSG instructions?

Don't need to use it real world, just curious.

Many thanks in advance.
