Reduced Size PLC I/O Mode Assemblies
For some PLC controllers, the data size footprint required for a given assembly can be a limiting factor on how many devices can connect to a given controller. ConveyLinx includes input/output assemblies with fewer registers that contain basic functions in applications where the full functionality of the PLC I/O Mode Assemblies is not required. The Reduced Size Assemblies provide basic I/O and motor control while removing the interfaces for servo moves, upstream/downstream data, tracking data, etc.
