Softstarters Type PST/PSTB Fieldbus communication Profibus DP V0 / V1 1SFC132013M0201 January 2005 1SFC132013M0201 1 Profibus DP V0 / V1 The Profibus DP V0 / V1 protocols are fieldbus protocols that provides full control and status information of the softstarter as well as writing of parameters (read and write for V1). Through the fieldbus it is possible to start and stop the motor, perform jog, sequence start, read out currents and frequency, achieve information about protections, warnings, faults and much more. See chapter “Setting and configuration” in the installation manual for programming of the inputs / outputs. Before the Profibus DP fieldbus can be taken in operation following parameters must be set in the softstarter: Parameter Fieldbus Ctrl set to Yes Parameter Fieldbus Type set to other Parameter Fieldbus Addr set to a free communication address. For technical data and descriptions of the Profibus DP fieldbus plug, see document 2CDC192001D0205, available at /lowvoltage . To do the programming of the PLC, following GSD files are available: GSD file Type of protocol ABB_078F.gsd Profibus DP V0 ABB_082d.gsd Profibus DP V1 Note that the GSD file contains information about different software versions of the softstarter. Check that correct part of the file is used in relation to the actual softstarter version. Caution! The motor may start unexpectedly if there is a start signal present when doing any of the actions listed below. • Switching from one type of control to another (fieldbus control / hardwire control) • Re-programming of the programmable inp uts • Reset all Settings (programmable input set to Enable) 1SFC132013M0201 2 Binary input telegram To PLC from Softstarter.
