PLC pre-wiring - retrofit interfaces

The obsolescence of the PLCs and the new industrial constraints most of the time require that the PLC be replaced without modifying the electrical installations already in place (sensors, actuators, cabinet wiring, etc.). It must be fast, to limit the downtime of the installation, reliable (without risk of errors) while retaining the possibility of maintaining the current process. Retrofit interfaces take these requirements into account, allowing parallel operation of two PLCs of different generations. Tests with the new PLC can be carried out while maintaining the operation of the current process with the old PLC, before switching the installation. Dedicated I/O modules are available, but retrofit interfaces are also compatible with all of the interfaces in our standard pre-wired range, through the use of interface modules.
