Another Okuma Question; High Speed Look Ahead

[danielm]

Well it turns out that   VOPRB[2]=VOPRB[2] EOR 128   is just a toggle switch that change the state of the HSLA buffer from off to on  or on to off....depending on its initial state.

VOPRB[2]=VOPRB[2] OR 128   Turns the HSLA buffer off no matter what

There has got to be a similar string that turns the HSLA buffer on no matter what.  I've been through the manuals and I cant find it.

 

Anyone run into this?

 

Thanks in advance for any help.

VOPRB[2] is an 8 bit (0-7) parameter. Bit seven determines whether or not buffering is on. For buffering to on, bit seven needs to be a 0. To always set it to be on you will need to do some logic checking. 

IF [VOPRB[2] LT 128] NSKP1

VOPRB[2]=VOPRB[2]-128

NSKP1

Also, for reference, you can check the VDIN variable to act as a one line look ahead limit in a program. VDIN[****] (where **** = 1000-1004) are system clocks for days, hours, minutes, seconds, milsec. If you write any one of those values to a variable the NC will not process that line of code until it reaches it in actual execution. This will act as a look ahead buffer. 

Example; 

TIME=VDIN[1001]
