Replace PLC systems safely and without downtime

Replace PLC systems safely and without downtime

When industrial plants age, are no longer state of the art, or when support or spare parts availability is limited, a system update is required at the control level of a process plant. When replacing PLC systems, it is crucial to avoid wiring errors and keep downtime during the migration process as low as possible.

PLC migration interfaces from Weidmüller enable the control level to be exchanged safely. Adjustments or changes to the infrastructure can also be made quickly and easily without having to intervene in the field wiring.

Benefit from a clever migration platform

Uniquely designed solution

Uniquely designed solution

The key to our migration platform is the design. It permits your existing field wiring to remain in place and undisturbed on the front panel adapter, and eliminates the need to wire-trace or ring-out.

Compatibility means flexibility

Compatibility means flexibility

The assembly is a universal conversion/migration system for main legacy PLC systems, enabling you to seamlessly migrate to any new control system.

The correct retrofitting components for each PLC

For each of the DCS systems from ABB, Emerson, FANUC, Honeywell, Mitsubishi, Omron, Rockwell, Schneider, and Siemens, we have sets of front adapters, rack systems and cables that are individually customised to guarantee you an efficient retrofitting process.

Space-saving bridging system

Convenient SPS/PLS changeover within a few hours

The PLC migration with our new migration interfaces does not require any additional space in the control cabinet. The rack system takes the place of the old controller and combines the connection level and the new controller into one compact unit. All connection components are easily accessible by simply folding down the upper level.

Space-saving bridging system
Your benefits
  • No additional space required in the control cabinet
  • Lower level: connection of the existing pre-assembled ?PLC cables to the new adapters, upper level: PLC is placed
  • Pre-assembled PLC interface cables connect the adapter ?cards with the new PLC

Retrofitting made easy - the migration process

Step 1

Step 1

Step 1

The new rack system takes the place of the old control so that no additional space is required in the panel.

Step 2

Step 2

Step 2

The relevant front adapter is used in the rack system so that the existing PLC cable connections and an end of the new pre-mounted cables can be inserted as the next step.

Step 3

Step 3

Step 3

In the last step, the rail with the new control is placed and connected to the other end of the pre-mounted cable.
