4.4.1 Introduction

Profile
No. Name
1 DX-NET-SWD 8 bit
2 DX-NET-SWD PD 2 x 16-Bit
VFD = DA1, DC1 variable frequency drive or DE1 variable speed starter
The amount of cyclical input/output data (process data) for the variable
frequency drive/variable speed starter can be adjusted as necessary for the
application at hand by using the various profiles. These profiles can be
selected in the hardware/PLC configuration program (in the SWD-Assist
program, for example).
Two cyclic profiles can be selected:
• Profile 1:
Control and status data will be processed as per the I/O link profile.
• Profile 2:
This group supplements the variable frequency drive profile with the
PROFIdrive profile as the PNO has defined for the cyclic data-exchange
with a drive. Control and status data will be processed according to the
PROFIdrive profile.
Profile 2 is set in the default settings.
