Modbus org docs Modbus over serial line Vl pdf The system supports three different hardware protocols RS 232 the standard RS 485 half duplex multidrop and the modified RS 485 full duplex multidrop protocol The user must configure the communication parameters to match those of the Modbus master controller The user must also properly configure the hardware connection on the I O board 28 4411 0009 Rev 0 6 System Operation All Modbus registers are 16 bit signed integers however most of the parameters are floating point numbers To obtain the actual floating point value of a parameter it s Modbus register value needs to be multiplied by the scale coefficient for that parameter The scale coefficients of all parameters are provided in Appendix B Parameter List in the column Scale For example if a user reads a value of 5051 for Parameter 801 Inverter AC Voltage using Modbus the actual value is 5051 x 0 1 505 1V 3 3 2 MODBUS Setup 3 3 2 1 MODBUS Parameter Configuration Device ID Baud Rate Data Bits Parity Stop Bits RS 232 485 Select Both RS 232 and RS 485 full duplex or half duplex standards are supported In RS 232 and RS 485 full duplex the transmitter is on continuously In RS 485 half duplex the transmitter is only powered when the device being polled is transmitting After setting the RS 232 485 Select to choose the protocol being used the protocols require that you
