Integrated PLC and Motion Controller
- Created: Thursday, 26 January 2012
The A3200 MotionPAC from Aerotech (Pittsburg, PA) is a software-based PLC that is integrated with Aerotech’s A3200 motion controller to increase programming efficiency and decrease development time. The MotionPAC can be used independently for full machine control or in conjunction with AeroBasic™ programs. Users can program in Ladder Diagrams (LD), Function Block Diagrams (FBD), or Structured Text (ST).
The MotionPAC's tight integration with the A3200 motion controller allows users to command asynchronous, coordinated, blended, geared or cammed motion directly from LD, FBD, ST or directly start or stop AeroBasic™ programs. Moves can be specified as relative or absolute in user units (either English or metric). CNC or G code also can be called from the PLC program.
Programmers can create shared variables and Tags that are referenced by Name in all of the A3200 tools, Operator Interface, AeroBasic™, C, or .NET programs. Memory management is automatically handled by the MotionPAC for all Tags and variables. MotionPAC tools such as user-definable libraries (LD, FBD, ST or .NET), integrated axis manager for readout and manual control, global Tag database, automatic memory management, and virtual execution of the PLC increase programming efficiency and quality.
