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 Standard ZPA Mode Assemblies is not required. The Reduced Size Assemblies provide basic accumulation and release control along with module diagnostic data while removing the interfaces for reading/writing tracking data.
