2 Functions of Devices in DVP-PLC Function Group Communication Response Delay Number D1038 Contents: 1. When PLC is used as slave station, in RS-485 communication interface, users can set up communication response delay time ranging from 0 to 10,000 (0 ~ 1 second). If the time is without the range, D1038 = O (time unit: 0.1ms). The set value of time must be less than that in D1000(scan time-out timer WDT). 2. In PLC LINK, you can set up delayed transmission of the next communication data (unit: 1 scan period for SA/SX/SC; 0.1ms for EH2/SV/EH3/SV2). Function Group Fixed Scan Time Number M1039, D1039 Contents: 1. When M1039 = On, the scan time of program is determined by the content in D1039.
When the execution of the program is completed, the next scan will take place when the fixed scan time is reached. If the content in D1039 is less than the actual scan time of the program, the scan time will follow the actual scan time of the program. M1000 Scan time is fixed to 20ms 2. Instructions related to scan time, RAMP (API 67), HKY (API 71), SEGL (API 74), ARWS (API 75) and PR (API 3. Particularly for HKY instruction, when the 16-digit button input is operated by 4x4 matrix, the scan time has to be 77) should be used together with “fixed scan time” or “constant interruption”. fixed to longer than 20ms. 4. The scan time in D1010 ~ D1012 also includes fixed scan time.
Function Group Analog Function Number D1056 ~ D1059, D1062, D1110 ~ D1113, D1116 ~ D1118 Contents: 1. Resolution of analog input channel: 10 bits for EX, corresponding to 0 ~ ±10 V (-512 ~ +511) or 0 ~ ±20 mA (-512 ~ +511); 12 bits for SX, corresponding to 0 ~ ±10 V (-2,000 ~ +2,000) or 0 ~ ± 20 mA (-1,000 ~ +1,000). 2.
