This library is targeted at S7-1200 and S7-1500. Finally, I know that the NModbus site was hacked and the documentation was lost. That is, to not have to user a timer or manually poll for data from a client PLC? I know an OPC Server is the ideal solution, but for only a couple PLCs, it’s too expensive. The main setpoint value (HSW) is to be transferred to the SINAMICS V20.Great article, are you familiar enough with NModbus (or the modbus protocol in general) to know if it has the ability to be event-driven. It requires the functionality described in the sections 1.1 to 1.3.Ĭyclic process data exchange All drives of the port are to be operated cyclically, one after the other.Ĭontrol data The complete control word (STW1) is to be transferred to the SINAMICS V20: Table 1-1: STW1 A controller is to operate up to 32 drives via one of the provided ports. Task SINAMICS V20 drives are to exchange data via the RS485 interface and via Modbus RTU with a SIMATIC S7-1200 controller.
