Westinghouse Numa Logic help needed!

[kevinrcase]

I have only a print-out from a Numa Logic PLC to convert to AB RS Logix code. Can anyone help me understanding some of the more complex Westinghouse Numa Logic registers.
Like a "SL" function with 3 inputs and a number of registers.
Can I assume this is a bit shift left? How does it work? there are no contacts associated with this function block.

Also "AM" function with with one input and matrix size, 1 end, 2 end what does this do? there is a contact for this function block.

Can I assume the following functions are self explained?

GE operand 1 Greater than/Equal to operand 2
EQ operand 1 equals operand 2
UC Up counter
DC Down Counter
MV move data from source to destination

You really need to get your hands on a manual. I had no luck with Google.

Best regards,

hello

I have a manual for the 700,900 and can help you if you e-mail me the section of code you wish to translate. I can't copy the manual, sorry!

I have search & searched. I could not find a westinghouse Numa Logic manual on line.

I need help on one function in particular:

there are 3 inputs into a function block. the second input is alway off. The function block specifies a starting regester as HR0098 and a number of registers of 1. The output is a bit register SL0268. This bit does not appear in the program as contacts. The 16 bit holding register is manipulated and capared with thought the program to preform logic.

Kevin,

Contact Eaton electrcal. http://www.eatonelectrical.com/NASApp/cs/ContentServer?pagename=C-H/CHHome/CHHomeMainPage

They may be able to help you with a manual. It is my understanding that Eaton/Cutler-hammer took over this portion of Westinghouse.

BTW, all I could find is a pdf on the above site that was a product discreption for the Westinghouse PLCs. No programming manuals...

good luck, Mike.

I had already did that. You can obtain part numbers and get sizes of modules & racks but that is about it!

Kevin,

You might have done this also, but check with PLCcenter.com. If you havent already I would suggest you phone Eaton, and/or PLCcenter.com and ask their tech people where you might find a programming manual.

Ive search quite a bit on the web for this too. At this point you might have to take a few stabs in the dark and start making phone calls to old westinghouse distributers, PLC repair shops etc..

It seems your in a tight spot. Sorry I cant be of much more help.

Mike.

Rely apreciated!! Kevin Combe's also a member offered me some help with the functionallity of the BSL or now i know the Bit Shift Left function. I think the remainder like counters compare statements etc are more or less self explanitiory by reading into the logic. But you never know i might call back on that help.
Yes you have the manual and i have the programming experience.
