It has been five years since you started this thread. Will you be upgrading the firmware to v20, or a newer version ?
What type of HMI devices or software does your system use ?
If you are just replacing a 1756-L71 with a 1756-L72 with the same firmware version, then you should have to change nothing in your HMI or your communication networks.
