From the right hardware directory to add the selected length (wuxi Emerson turn Modbus Profinet gateway )
Download the configuration to the PLC
Open the wuxi Emerson Modbus Profinet gateway configuration software for Modbus parameters configuration, click the red circle in the new, choose PN2MM
Set the wuxi Emerson turned Modbus Profinet gateway (MCN - PN3001) name, IP address, and equipment to be consistent and PLC configuration
Set of wuxi Emerson Modbus Profinet gateway (MCN - PN3001) parameters of 485 baud rate, data bits, parity to and from the station to remain consistent,
Response to wait for and polling delay according to adjust the time interval from the station equipment, if from standing up the response speed is slow response latency, if request waiting for a period of time after reply from the station to receive the command, then the polling delay must be large
Right-click on the Modbus RTU inserted in the lower menu, click on the Node number fill out from USA
Continue to right click on the insert
According to different needs to choose the required function
According to the inverter manual description, record the parameters needed for
In this case 485 parameter is set to:
Baud rate: 9600
Data bits: 8
Check digit: no check
Stop bits: 2
Set the inverter controlled by modbus start-stop, given speed
According to the example message display, station number is 2, the use of 6 function code (single register write) register address 0 (note: some equipment register address starting address is not 0, so may need to be done to address offset)
To choose to write a single register
Memory mapped address corresponding to the starting address of the PLC in the Q address in this case, the QB64
After download configuration connection PLC and from station equipment
Of PLC address've written respectively, 1142, 1143, 1151 (decimal) control inverter from the
