Hello,

we have developped a web application that could be useful for FACTORY I/O users :

[https://crestic-fiotoplcmdb.univ-reims.fr/modbus\_generator.php](https://crestic-fiotoplcmdb.univ-reims.fr/modbus_generator.php)

When you design a FACTORY I/O big scene, it takes time to map all FIO variales for the driver Mosbus TCP. This web application allows to automatically generate the Modbus TCP/IP Client mapping of all variables in your Factory I/O scene. The generation have Offsets or not.

In addition, if you want an other driver, you can after use in the FIO console “drivers.apply\_current\_mapping\_to\_all()” to apply tags mapping of the Modbus TCP/IP Client to all drivers.

Have a nice day,

Bernard
