With the Modbus interface, WILO offers an industry standard which has been proven at a global level.

The protocol structure is as easy as it is widespread. The well-known RS485 technology with the RTU protocol is used. The Wilo-Modbus implementation is realized by using the RTU protocol. The data points of the IF-Modules are largely compatible with those available via the Wilo-DigiCon Modbus. So a safe changeover and easy upgrade to the module-based architecture is possible.
