The standard blocks in the PLA include: The logical step has been to offer that applications functionality for use as a stand-alone module that can be used to enhance any control system - This is the PLA applications module. The PLA provides an applications module that can compliment and enhance any analogue or digital drive control system, simplifying system design and reducing or eliminating the need for costly extended functionality on PLC or PC based systems. Designed primarily for use by system integrators, the PLA offers extremely powerful and flexible method of processing analogue and digital signals via easy to use configurable software blocks. Evolved from Sprint Electrics PLX series of DC drives, the PLA is packed with many features and functions that are often required by engineers in producing solutions for diverse applications and motion tasks. The PLA offers a means of interconnecting analogue and digital signals via its range of configurable inputs and outputs to the internal application blocks, enabling the user to define a control strategy to exactly meet the demands of the process or application. The block diagram created is extremely flexible and has a unique "Configuration Checker" detecting shorts within the user defined connections. With drive and plc functionality merging closer together, the extended functionality of the Sprint digital drive offers more than just drive control PLA applications module
