Chapter 6 Applied Instructions 6-173 Data Setting Device number Function Description type range 2: Automatic control When PID MAN is _ switched from ON to OFF, the MV involved in the internal algorithm is involved in the automatic algorithm. If the setting value exceeds the range, it will be counts as 0. PID MAN _ BOOL PID A/M mode True: Manual The MV is output according to the MOUT, but it is still within the range between the MV MIN _ and the MV MAX. _ When PID MODE is _ set to 1, the setting is ineffective. False: Automatic The MV is output according to the PID algorithm, and the output value is within the range between MV MIN and _ MV MAX.
_ MOUT AUTO _ BOOL MOUT automatic change mode True: Automatic The MOUT varies with the MV. False: Normal The MOUT deos not vary with the MV. Cycle Double word/DINT Sampling time (T ) S 1~2,000 (unit: 10ms) When the instruction is scanned, the PID algorithm is implmented according to the sampling time, and the MV is refreshed. If T S is less than 1, it will be count as 1. If T is larger S than 2000, it will be count as 2000. When the instruction PID is used in the interval interrupt task,
