A Local Controller device installed in or on the fuel pump capable of functioning as a pump controller dedicated solely to the pump in which it is installed and as a data router to and from the peripheral devices. This dedicated Local Controller device contains a microcomputer with a pump communications interface and optionally a remote, Site Controller communication interface which is non-dedicated and has control over many pumps at the station. If connected to such a Site Controller, the device will function as a slave to this Site Controller. Otherwise it functions autonomously to control the pump on its own. |
