Software
VersaPro
The VersaPro (version 1.1 or later) software package is used for the following tasks:
•
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 PLC’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 PLC. This would be due to (1) the delay
in communicating the signals across the backplane and (2) the longer PLC sweep time.
All of the above information is sent to the DSM314 over the PLC backplane each time the PLC is
powered up.
Note
VersaPro version 1.5 or later, with the CAM Editor add-in software, is required
for programming the electronic CAM feature.
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 PLC through
discrete I/O modules or an intelligent serial communications or network communications module.
Operator data is automatically transferred between the PLC and the DSM314 through %I, %AI,
%Q, and %AQ references which 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 Series 90-30 PLC.
