Name :Multi-segment pulse output

Symbol:PTO

Illustrate:

    With this function block, you can control the pulse output, which makes the pulse of the duty cycle 50%, and can control the multi-segment pulse output to achieve the effect of outputting a specified number of pulses at a certain speed and acceleration

Parameter:

Parameter Statement IN/OUT Parameter role Illustrate Default value
OUTPORT UDINT IN Pulse output port 0-7 
not
EXECUTE BOOL IN The function block is enabled Rising edge trigger (after triggering, it cannot be triggered again if it is not completed) 
Yes/FALSE
PULSESECNUM UINT IN The number of pulse output segments EXECUTE rising edge 
not
PULSESECINFO T_PULSE_SEC_INFO * IN Pulse segment structure array first address: describes the information of each pulse segment EXECUTE the rising edge 
not
ABORT BOOL IN Emergency stop triggering TRUE：Emergency stop enabled (irrevocable after enabled, and cannot be re-enabled until the processing is completed) 
Yes/FALSE
STOPTIME UDINT IN Emergency stop time: Units ms Stop the pulse output within the set time. NON-0;0: RUNS BY DEFAULT (LOADED ON EXECUTE RISING EDGE) 
Yes/5
DONE BOOL OUT All pulse segments are output to the mark of completion TRUE：Pulse segment output completed (status retention for 1 cycle) 
Yes/FALSE
BUSY BOOL OUT Pulse output status TRUE：The pulse is being output 
Yes/FALSE
CMDSTOP BOOL OUT Emergency stop status TRUE：During the emergency stop, the pulse frequency has not been reduced to 0 (at this time, it is not possible to respond to the new axis start control)） 
Yes/FALSE
ERROR BOOL OUT Error flags TRUE：There was an error with the function block call 
Yes/FALSE
ERRORID DINT OUT Error codes 0：Normal, Other: Error code value 
Yes/0

4 
The number of pulse segments is 0
5 
The pulse segment buffer is empty
6 
The number of pulses is 0
7 
The frequency exceeds the maximum allowable range
8

9 
The two segments have different pulse directions

Interpretation:



   IF OUTPORT IS 0, THE 0TH PULSE IS USED;
   EXECUTE is the rising edge, which means that the operation is valid and the function block is started;
   PULSESECNUM IS 1, WHICH MEANS THAT THE FUNCTION BLOCK ONLY EXECUTES THE OUTPUT OF ONE PULSE SEGMENT.
   The description of the multi-pulse segments is stored in PulseSecInfoRef: the start frequency, end frequency, number of pulses + direction of each segment;
   If ABORT is FALSE, the emergency stop is not being performed at this time.
   A STOPTIME of 100 indicates that the pulse frequency needs to be slowed down to 0 within 100 ms when an emergency stop is performed.
   If DoneOut is TRUE, the output of the multi-segment pulse has been completed.
   If BusyOut is TRUE, it means that the function block is outputting multiple pulses;
   If CmdStopOut is TRUE, it means that the function block is making an emergency stop and has not yet slowed down to zero.
   If ErrorOut is set to TRUE, the function block is faulty and the error code is ErrorIDOut.
