When there are many high speed output instructions (PLSY, PWM, PLSR) for Y0 output in a program, PLC will only execute the settings and outputs of the instruction that is first enabled. 3. More explanations on M1347 and M1348:
If M1347 and M1348 is enabled, and when the execution of PLSY instruction has been completed, M1347/M1348 will be reset automatically, i.e. you do not have to turn the status of the drive contact from Off to On before PLSY instruction and when PLC scans to the instruction (assume the drive contact of the instruction is True), there will still be pulse output. PLC detects the status of M1347 and M1348 when END instruction is being executed. Therefore, when the pulse output is completed and if PLSY instruction is a continuous execution one, there will be a scan time of delay in the next string of pulse output. Program Example 1: EI M1000 FEND I 001 IRET I 101 M1000 IRET END Explanations:
a) Whenever X0 is triggered, Y0 will output 1,000 pulses; whenever X1 is triggered, Y2 will output 1,000 pulses. b) When X triggers Y pulse output, there should be an interval of at least one scan time between the end of Y pulse output and the next X-triggered output.
