Fieldbus communication (option)
8:1 Overview
The PST softstarter has an interface on the front for connecting the ABB fieldbus plug is
used for fieldbus communication. Through this interface, it is possible to control the soft-
starter, achieve status information, as well as upload and down-load parameters.
The interface between the softstarter and the eplug is always the same. Independent of
softstarter size, it is possible to connect any fieldbus protocol in the future since the protocol
is defined in the eplug itself.
The following fieldbus protocols are available:
• AS-Interface
• DeviceNet
• Profibus DP
• Modbus
8:1.1 Required accessories
To connect the softstarter to a fieldbus system, the following accessories are required:
• Fieldbusplug for appropriate protocol (check that the cable length is sufficient).
