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
