Chapter 8 - Fieldbus communication (option)

Overview

The PST softstarter has an interface on the front for connecting the ABB fieldbus
plug (eplug) which is used for fieldbus communication. Through this interface, it
is possible to control the softstarter, achieve status information, as well as upload
and down-load parameters.
The interface between the softstarter and the eplug is always the same. Indepen-
dent 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-I
• DeviceNet
• Profibus DP
• Modbus (Available Fall 2003)

required:
• Fieldbusplug for appropriate protocol (check that the cable length is suffi-
cient).
