Usually these bits being used in the LAD programs on PLC. You may block up or activate any line of LAD, where separate bits are used. They being named OP... If you have an opportunity to look at LAD you have to find them there. As for me, i have blocked up the "open door alarm" on Tsugami NU4B (controller 10T).

THANKS FRIENDS,

BUT I WAS TOLD THAT THERE ARE SOME KEEPRELAYS WHICH ARE RESERVED BY FANUC.

IS IT SO?

That's correct, but some of them are control specific. For example, you can block out the ladder edit function on some of the controls by a keeprelay.

What control are you working with? Any specific keep bits you're looking for or just a general list?

How do you find the keep relay that operates the open door alarm?? I have found it in the ladder but dont know how to find the right keeprelay.

In my ladder door alarm is the line 26F. Item OP7 (K000.7).
This means: keeprelay #0, bit 7. Reset this bit and check the result in the ladder. If you resetted the proper bit, the "normal open contact OP7" becomes dim. Bit 7 - 1st at the left.

Hi.
First of all, set PWE bit in 8000 parameter.
26F means: page 26 of ladder listing, F - string on the page.
What type of the controller on your machine? If 10 series, push key "NC/PC", then push software key (on the CRT) "keeprelay". And then set or reset bits in bytes you see on the screen.

I have few explanation of keeprelay settings.

K17#0 protect pmclad display (0=unprotect 1=protect)
K17#1 programmer enable (0=off 1=on)
K17#2 Ladder start (0=auto 1=manual)
K17#4 Ram write enable (0=no 1=yes)
K17#5 Signal trace (0=manual 1=auto)
K17#7 Pmc param. data table screen (0=show 1=hide)
K18#2 Signal trigger start (0=manual 1=auto)

there are some differences for the different types. For complete information, please refer to the manual B-61863E / 15 page 484.
