Overview
The PST softstarter has an interface on the front for
connecting the ABB fieldbus plug 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 fieldbus plug 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 fieldbus plug itself.
Following fieldbus protocols are available
• AS-Interface
• DeviceNet
• Profibus DP
• Modbus
To connect the softstarter to a fieldbus system, following
accessories are required:
• Fieldbusplug for present fieldbus protocol (check that the
cable length is sufficient).
• Connectors for bus connection.
• End plug (some protocols).
• Software for PLC set-up.
