Motion Control Commands in QuickBuilder
Motion control is programmed identically whether you are using IncentivePLC and IncentiveECAT on an embedded PC, or the dedicated Series 5300 Programmable Automation Controllers. Motion Sequence Blocks (MSBs) are programs formed using the commands below, which are then downloaded into the IncentiveECAT program or Series 5300 motion control board for local execution. This ensures optimum performance by keeping the motion program execution independent of the main or supervisory control, while still allowing for intensive intercommunication between program components.
MSBs are written using the QuickBuilder Programming Environment as part of your overall control program. They may be triggered by events in your main program, or written to sense and respond to events local to the motion subsystem. For detailed information on programming MSBs, including full descriptions of each of these commands, download the QuickBuilder Reference Guide.
