Configuring via Modbus RTU Described in the following chapters is how you can establish the communication. The controller is set to slave address 5ex works , baud rate 19200 baud, even parity, 1 stop bit. All changes take effect only after the controller is restarted. Communication settings The following settings can be performed: Configuration Object Value range Factory settings Slave address 2028h 1 to 247 5 Baud rate 202Ah 7200 to 256000 19200 Parity 202Dh None: 0x00 Even: 0x04 Odd: 0x06 0x04 (Even) The number of data bits is always "8" here. The number of stop bits is dependent on the parity setting: No parity: 2 stop bits "Even" or "Odd" parity: 1 stop bit The following baud rates are supported: 7200 9600 14400 19200 38400 56000 57600 115200 128000 256000 You must save the changes by writing value "65766173h" in object 1010h:0Bh. The changes are not taken over until after the controller has been restarted. Establishing communication Connect the Modbus master to the controller via the RS-485+ and RS-485- (see X7 − CANopen/RS-485 IN) or RS-232-Tx and RS232-Rx (see X4 − RS-232 connection) cables. If using RS-485, mount jumpers J1 and J2 in the correct position (see RS-485 setting). Supply the controller with voltage. Change the configuration values if necessary. The controller is set to slave address 5ex works , baud rate 19200 baud, even parity, 1 stop bit. To test the interface, send bytes 05 65 55 00 2F A7 to the controller (you can find a detailed description of the Modbus function codes in chapter Modbus RTU). The object dictionary is read out.
