Software
The DSM314 requires one of the following configuration/programming software packages:
•
Machine Edition Logic Developer – PLC, version 4.5 or later for RX3i
•
Machine Edition Logic Developer – PLC, version 2.1 or later, or VersaPro, version 1.1
or later for Series 90-30
The programming/configuration software package is used for the following tasks. The
information created by these tasks is sent to the DSM314 over the host controller backplane
each time the host controller is powered up.
•
Configuration. Allows user to select module settings and default operational
parameters.
•
Motion program creation. Up to 10 motion programs and 40 subroutines are
allowed.
•
Local Logic program creation. A Local Logic program runs synchronously with the
motion program but is independent of the host controller’s CPU scan. This allows
the DSM314 to interact quickly with motion I/O signals on its faceplate connectors.
This internal response time to motion I/O signals is much faster than would be
possible if the logic for these signals was handled in the main ladder program
running in the host controller. This is due to (1) the delay in communicating the
signals across the backplane and (2) the longer host controller sweep time.
•
CAM profile creation. A CAM profile specifies the response of a follower servo to a
master position index. CAM profiles are referenced by name in the associated
motion program.
Note: The CAM editor is fully integrated with Logic Developer – PLC.
Operator Interfaces
Operator interfaces provide a way for the operator to control and monitor the servo system
through a control panel or CRT display. These interfaces communicate with the host
controller through discrete I/O modules or an intelligent serial communications or network
communications module.
Operator data is automatically transferred between the host controller and the DSM314
through %I, %AI, %Q, and %AQ references that are specified when the module is configured.
This automatic transfer of data provides a flexible and simple interface to a variety of
operator interfaces that can interface to the host controller.
