Line.
The output of PLC is controlled by step 2
When needing the output frequency changing ABB converter, first PLC outfan exports high eight-bit binary data, time delay 10
Millisecond；Secondly PLC output zero, time delay 10 milliseconds；The last PLC outfan low eight-digit binary number data of output, time delay 10 milliseconds,
Output zero.
The data of single-chip microcomputer are stored and control by step 3
First, the input of single-chip microcomputer receives the high eight-bit binary data that PLC exports the high eight-bit binary number that will receive
According to storing to data register, move to right eight；Secondly, the input of single-chip microcomputer receives the low eight-digit binary number data of PLC output；
Finally, the high eight-bit binary data received and low eight-digit binary number data are synthesized sixteen bit data by computing by single-chip microcomputer.
The output frequency of ABB converter is controlled by step 4
First, ABB converter utilizes the RS485 communication terminal of RS485 communication terminal and single-chip microcomputer carry out MODBUS communication and connect
Receive the sixteen bit data of single-chip microcomputer output；Finally, ABB converter changes output frequency according to the sixteen bit data received.
Beneficial effects of the present invention: the present invention has broken away from steel skeleton composite production line to ABB inverter communication board
Rely on, utilize single-chip microcomputer to replace ABB inverter communication board to realize PLC to the communication of ABB converter and control, solve ABB
The problem that inverter communication board produces due to the long impact of delivery cycle after damaging.The means of communication of the present invention are simple, implement
With low cost, run and easy to maintenance, control flexibly and be not take up PLC PORT COM.
