Legacy Replacement
Many older PLCs have reached or are reaching end of life and are no
longer supported by their manufacturer. Spare parts are difficult to
come by and where they are available it is at a premium price.
Many of these PLCs are currently running critical processes in a number
of industries. Replacement of these systems with supportable systems
is essential to maintain smooth operation and profitability of the
affected processes.
WIAC Ltd have worked on a number of legacy replacement projects,
implemented on both a like for like and complete redesign basis.
WIAC Ltd can advise on legacy replacement solutions to suit your
requirements and your budget. Advising on software conversion issues,
