The Pump Setup can be complicated, but since we are focusing only on the Mechanical Pump, we can keep it simple but we also want to be sure that the setup can cater for the future requirements.
NB: On the Multi-Nozzle Digital Pumps: There are two type of Pump methods re:the Polling - one (e.g. SM2000/8) where each Logical number as defined (with Mech Pumps) will be polled as in the setup below sequentially. So we will Poll Nozzle 1, then 2, then 3 etc and each will get its own response. It important to understand that when a Nozzle is active (i.e Not IDLE), then all the other Nozzle on that PUMP will not be able to change status until the Active Nozzle completes its cycle of action. So the system can be more efficient by not polling the other Nozzles and these can be identified by the common Pump Physical#. This can be managed by storing the ACTIVENOZZLENUMBER and polling just that one and ignoring the others. The Composite Type, is the other Pump type (e.g. Dresser Waynes). In this case the Pump may have 1-5 nozzle each, but you poll the Pump, not the Nozzle. This is more efficient as you poll one Pump, instead of 5 Nozzle in the previous example. When a Nozzle is active, the Protocol will report which Nozzle is active and you will use this Nozzle Number as the
ACTIVENOZZLENUMBER and it will be used to retrieve the Sale and Totalizer from that Nozzle. Each of the Tagging type can be disabled or activated individually

I was planning to do another table with Logical Number : Physical Numbers but maybe I could just use the Physical number directly instead.
