1. The PLSR/PLSA/EPLSR instruction for multi segment pulse output can be used to achieve multi segment pulse output at a preset frequency and number of pulses. The output conversion between different segments should be completed within the preset acceleration and deceleration time. When the input terminal is turned on, immediately output pulses from the starting frequency of the first segment, accelerate to the preset frequency of the first segment within the predetermined acceleration and deceleration time, and when the number of output pulses reaches the preset number of output pulses of the first segment; Accelerate and decelerate to the second preset frequency within the predetermined acceleration and deceleration time. When the number of output pulses reaches the second preset output pulse, execute according to the third preset value until the number of segment pulses is set to 0 or the frequency is set to 0, indicating the end of the segment, and the pulse output stops.

2. The set values for multi segment frequency and pulse number are set in the pulse parameter address. A region starting from Dn.

3. The 32-bit PLSR/PLSA/EPLSR command can output a frequency range of 0Hz~200KHz and a pulse range of K0~K2147483647. The acceleration and deceleration time of each section of PLSR/PLSA is the same, while the acceleration and deceleration time of each section of EPLSR can be set separately, and the acceleration and deceleration time of the last section can be set separately.

每段设定脉冲频率，脉冲个数和加减速时间满足关系式：（起始频率Hz + 结束频率Hz）×（ 加减速时间ms÷1000） <= 脉冲个数 × 2。

4. 单向相对位置多段脉冲输出PLSR脉冲方向Y只由第一段设定的脉冲个数或者脉冲频率的正负决定，当第一段设定的脉冲个数或者频率为正数时，为正方向，Y输出为ON；当设定的脉冲个数或者频率为负数时，为负方向，Y输出为OFF。对于绝对定位指令PLSA，脉冲个数代表其绝对位置，各段的正负可不相同，会自动变换方向。

For bidirectional relative position multi segment pulse output EPLSR pulse direction, the direction is determined by the positive or negative number of pulses in each segment. When the positive or negative number of pulses in this segment changes relative to the previous segment, the previous segment will slow down to 0, and this segment will accelerate in reverse from 0 to the frequency of this segment. The direction can be automatically changed based on the positive or negative number of pulses in each segment, and the acceleration and deceleration times can be set separately for the last segment.

5. The special function register M8068 is used for directional polarity control. The default pulse direction output port is ON, which indicates the positive direction, and OFF, which indicates the negative direction. If M8068 is set to ON, the polarity of the directional output of all pulse commands will be reversed, with OFF indicating positive direction and ON indicating negative direction.

6. For 16 point transistor type PLCs, Y0~Y1 are high-speed pulse output ports, and for 32/50/66 point transistor type PLCs, Y0~Y3 are high-speed pulse output ports; Relay type PLCs do not have high-speed pulse function, and the maximum output frequency of the output port is determined by the closing time of the relay. For multi pulse series PLCs, their high-speed pulse output ports are Y0~Y7 and Y10~Y11.

When the special function register M8069 is ON, the acceleration and deceleration of all pulse instructions are S-shaped, and when it is OFF, they are trapezoidal.

During the process of sending multiple pulse segments, when the pulse has not yet been sent to that segment, the parameters of that segment can be changed arbitrarily. When running to this segment, it will run with the new parameters. But when the pulse is sent to the previous segment of the pulse, do not change the parameters of that segment to 0, otherwise it will cause a sudden frequency change in the final segment. Similarly, the D register, which was originally the end flag, can be modified to include parameterized pulse segments to achieve the function of adding pulse segments;

After detecting the X0 signal, run 50000 pulses to stop pulse transmission. The program is as follows. Firstly, send pulses at a frequency of 50KHz, with a pulse count of -1 indicating continuous pulse transmission. When X0 detects a rising edge signal, it performs PLSNNEXT segment switching and enters the next segment, with a pulse frequency of 20KHz and 50000 pulses in the next segment. During the first stage of operation, the value of 50000 pulses for the second stage can be modified. If the pulse quantity for the second stage is unknown before starting the first stage, a parameter can be set arbitrarily (cannot be 0) and modified before switching stages.
