The PST softstarter has an interface on the front for
connecting the ABB fieldbus plug (eplug) used for fieldbus
communication. Through this interface it is possible to
control the softstarter, achieve status information, as well
as up and down-load of parameters.
The interface between the softstarter and the eplug is
always the same. Independent of softstarter size or
delivery date it is possible to connect any fieldbus protocol
later on since this is defined in the eplug itself.
