2 Functions of Devices in DVP-PLC COM2: (9,600, 8, E, 1, RTU) M1002 3. EH2/SV/EH3/SV2 series MPU supports the generation of interruption I170 when the data receiving is completed in Slave mode. 4. Normally when the communication terminal of the PLC is in Slave mode, PLC will not immediately process the communication data entered but process it after the END is executed. Therefore, when the scan time is very long and you need the communication data to be processed immediately, you can use interruption I170 for this matter. 5.
Example of interruption I170 (after the data receiving is completed in Slave mode) M1002 FEND I170 IRET END With I170 in the program, when COM2 is in Slave mode and there are communication data coming in, PLC will process the data and respond immediately. Notes: 1. DO NOT update program on-line when using I170. Definitions of the pins in COM1: (It is suggested that the Delta communication cable DVPACAB2A30.) 2. The scan time of PLC will be slightly longer. 3000 50 ± CN1 CN2 1 3 6 CN1 4 5 2 8 7 Unit : mm DVP-PLC Application Manual 2-84 MOV H86 D1120 SET M1120 SET M1143 EI MOV H86 D1120 SET M1120 SET M1143 31.
