Need help on mSec Pulse

[MichaelST]

I am new to PLC programming, I need a pulse function that can run with 500mSec, I have found out there are 2 standard features, a 1 Sec and on 100mSe. 

 

I have tried to do something by 2 timers, but I'm not completely satisfied. is there an easy or better way to do this. 

 

My plc is JZ10-11-T40

Hello Michael,

 

Thank you for using our Unitronics Forum.

 

We do not have a system bit that will perform a one shot every 500ms.  What you can do it create ladder for it using our timer.  Please follow the logic below:

 

* coils are notated by ---(   )---   and contacts by ---[   ]---

   and I have written what they should be/related to inside them. 

 

Net 1: ---[ Inverted contact: Timer0 (00:00:00.50) ]--- ---( Timer Coil: Timer0 (00:00:00.50) )---

 

Net 2: ---[ Positive Transition contact: Timer0 (00:00:00.50) ]--- ---( Whatever you are trying to activate )---

 

 

By this logic above, a one-shot pulse will be generated every 500ms. 

 

Please let me know if this helps, or if this is not the type of pulse you were referring to.

You could also use a continuous drum with two steps one for on, one for off to cycle a target MB.

Just another alternative solution..

 

SB3 (1 Second pulse) is on for 500mS and off for 500mS.

If you "OR" the positive and negative transition contact of SB3 you will get a pulse every 500mS.
