hallo, You can use USS protocol to communicate PLC and drive, but check if your drive accept it. Please, take a look on Siemens web site for USS protocol between S7-200 and MicroMaster (Siemens' drive), you will have a good idea about it there. Best regards, Berg

Can the Lenze drives talk Modbus? If so you can get the Modbus master code here in the forum. Or else as the others have stated you can use USS Protocol which is what the Siemens drives speak. Good luck!
