Emulation modes
FPBA-01 supports emulation modes for RPBA-01, NPBA-02,
NPBA-12 and VIK-NAMUR.
Emulation modes change the FPBA-01 identification information
so that FPBA-01 accepts connection from PLC configuration made
for RPBA-01, NPBA-02, NPBA-12 or VIK-NAMUR.
Emulation mode can be used in these conditions:
•
when replacing an older drive
•
where the PLC program cannot be changed
•
when using ACS880 as a VIK-NAMUR drive.
RPBA-01, NPBA-02 and NPBA-12 modes
Cyclic process data is handled based on profile selection. Control
word, status word, references and actuals can be used normally
according to the configured profile.
PROFIdrive parameter handling in cyclic data (PKW DP-V0) is
emulated. The parameter addresses can be modified to convert
the request to drive parameter index similarly as in the emulated
modules.
Note : Emulation mode only emulates parameter addresses. The
emulated parameters need to be made on the drive side with
application programming tools.
VIK-NAMUR mode
The VIK-NAMUR mode can be used in combination with ACS880
NAMUR application. With this mode, FPBA-01 acts in the
transparent mode and the drive application provides cyclic data
content for Standard telegram 20.
Use this mode with the generic VIK-NAMUR GSD file
( pd013aa0.gsd ).
Note : In NPBA-x2 and VIK-NAMUR emulation mode the cut-off
timeout is constantly 30ms.
