No these FBs are for ptp CPU onboard port. You HAVE to buy the modbus license from Siemens. |

Hello Vithani; In the MM440, the parameter for USS node address is P 2011, and its value must be 0-31. See this Tips and Tricks project diocumentation for the S7-200 USS protocol with a MM420: 2,5 Parameters for the MM420 ... //P0700=5 Set local/remote control mode by setting //P1000=5 Set local/remote control mode by setting //P2010 Index 0 Value 7 (19200) Baud rate //P2011 Index 0 Address 1 (0 to 31) Slave address //P1120= 0.00 (0 to 650.00) Acceleration ramp //P1121= 0.00 (0.00 to 650.00) Deceleration ramp // // Set the serial link timeout by setting: //P2014 Index 0 Value 300 (0 to 65535 ms) // Value 0 is without monitoring // When you change this value, the PLC must already carry out the // USS protocol, as otherwise Error 72 is immediately reported. // You must also change the value with the arrow pointing down, // as the first value would be 1 ms if the arrow were pointing up, resulting // in the immediate reporting of an error. ,,, Attached you will find a pdf version of the complete Tip documentation.
