The Enabler supports a maximum of 99 pumps with up to 8 nozzles on each.
Depending on how the pumps are connected, other restrictions may apply. To understand these, we need to describe some basic concepts.
If you are unsure if a particular configuration is supported, please contact us.
A physical pump usually has two sides, therefore one physical pump usually consists of two logical pumps.
A logical pump may have a single nozzle, or it may have more than one nozzle each with a different grade of fuel.
Other limits may apply, depending on the type of pumps, and how the pumps are connected. Our pump connection articles have detailed information.
Ports 1-3 can be used for any protocol.
Port 4 can be used for any protocol except those that use RS485 (FDM082 - Passive).
Logical pumps per port: max 16 (address range 1 to 16)
Physical connections per port: 8 (except EPS: 6) - this is determined by the FDM used.
Normally, a physical pump shares one connection between both sides.
Certain pump types require separate connections for each side, meaning that two connections are used up for every physical pump. In this case only 4 physical pumps can be connected to one port.
