Actuators with embedded Modbus communication Modbus is part of our IC™ programme and is a well-known communication technology that has been on the market for years. Modbus simplifies the communication, meaning you can connect several solar trackers in serial and thereby eliminate the need for lots of signal cables and still control the whole park from a central point. Besides from improving your return on investment, Modbus has many other advantages: Lower investment • Less complex system • Less cables due to BUS topology • Less need for I/O boxes • Less programming time due to standard communication language • Less installation time as the number of components are reduced and the control of the solution is embedded • Everything programmable and controllable from a central controller • One scalable solution for different sizes of installations Longer lifetime • Electronic overload protection protects the actuator. The current can be adjusted in both directions. • Lowering of speed and soft-start and stop reduce the wear on mechanical parts • Temperature surveillance and alarm 4
