5 Categories and Use of Basic Application InstructionsDVP-PM Operation Instruction5-92Program Example 3:1. In the communication between DVP-PM and VFD-B series AC motor drive (ASCII Mode, M1143 = OFF),executes Retry when communication time-out, data receiving error or parameter error occurs.2. When X0 = ON, DVP-PM will write data H1770 K6000) into address H0100 in device 01 (VFD-B).3. M1129 will be ON when communication time-out occurs. The program will trigger M1129 and send request forreading the data again.4. M1140 will be ON when data receiving error occurs. The program will trigger M1140 and send request forreading the data again.5. M1141 will be ON when parameter error occurs. The program will trigger M1141 and send request for readingthe data again.M1002MOV H87 D1120SET M1120Set communication protocol as 9600, 8, E, 1Retain communication protocolSet communication timeout as 100msMODWR K1 H0100 H1770X0Set communication instruction:Data address:Data: H1770H0100Device address: 01X0M1129M1140M1141Sending requestRetry when communication time-out occursRetry when data receiving error occursRetry when parameter error occursRST M1127M1127RST M1129Receiving completedProcessing received data The received data is stored in D1070-D1085i .n ASCII formatReset M1127Reset M1129 (receiving timeout)MOV K100 D1129SET M1122M1129Program Example 4:1. In the communication between DVP-PM and VFD-B series AC motor drive (ASCII Mode, M1143 = OFF),executes Retry when communication time-out, data receiving error or parameter error occurs. Set the times ofretry as 3 in D0. When communication retry is successful, the communication can again be triggered by users.2. When X0 = ON, PLC will write data H1770 (K6000) into address H0100 in device 01 (VFD-B).3. M1129 will be ON when communication time-out occurs. The program will trigger M1129 and send request forreading the data again. The specified times of retry: 3 (D0 = 3).4. M1140 will be ON when data receiving error occurs. The program will trigger M1140 and send request forreading the data again. The specified times of retry: 3 (D0 = 3).5. M1141 will be ON when parameter error occurs. The program will trigger M1141 and send request for reading
