Import/Export Revision History C-5
Motion Changes to Support
the SERCOS Protocol
Version 2.0 (major revision 2, minor revision 0) of the import/export
utility that is included with RSLogix 5000 programming software,
version 9.0 made significant changes to motion-related tags to support
the SERCOS protocol:
•
CoarseUpdatePeriod and AutoTagUpdate parameters were
added to the MOTION_GROUP tag to support SERCOS. For
reference, the previous structure is described below (page C-6).
•
Earlier versions of the import/export utility supported one AXIS
tag. To support SERCOS, the import/export utility replaced AXIS
with four different axis tags: AXIS_CONSUMED, AXIS_SERVO,
AXIS_SERVO_DRIVE, and AXIS_VIRTUAL (see pages 3-16
through 3-22). The previous AXIS tag is incorporated into these
new tags, but no longer exists as its own tag. For reference, the
AXIS structure is described below (page C-6).
If you have a version 8.0 import/export file with AXIS tags that
you import into version 9.0 software (after changing the
import/export version line to 2.0), the AXIS tags convert to:
If the AXIS type is: It converts to:
