Help on old ABB

Hi guys! I need some help on some old ABB PLC.
My experience is only with SIEMENS and Ladder programming.
I was given a project which is to replace an old ABB PLC with a new PLC in a dairy factory. They have given me the programming software(DOS) which when I run it says "PROCONTIC Version 2.2" and when I open the runtime software on the PLC type it says "Procontic b4" .
They have also given me a printout of the program which is approx 100 pages A4 size. The are are three backplanes with i/o cards , a total of 22x8 inputs and 29X8 outputs.
Looking at the program it has a format as follows:

0000
00000 ! s 00,01 step 1
00001 / s 00,03 step 3
00002 / s 00,05 step 5
e.t.c
00016 = M 00,00 BIT 1
0001
00017 ! S 00,02 step 2
00018 / S 00,03 step 3

Unfortunately I don't understand anything and as there is nobody which can explain the process in detail I wonder if anybody can give me some hints in order to understand the program.

GEOFRA,

You should search for a manual on the PROCONTIC Version 2.2 PLC software. I have never seen one myself, but I have seen many other brands.

00000 ! s 00,01 step 1

Here are some guesses based on experience. The 5-digit number is the program line number. The next position is an operator that tells the PLC to perform some function. The next two two-digit numbers are input or output bit locations. The ASCII text is user documentation put in by the programmer that tells something about the rung, what it is doing.

Since a Google search for "proconic" only lands 6 hits, of which 1/2 seem relevant, I'm guessing that finding a manual will be all but impossible. You never know though, someone here might have used these. Tim got me out of a jam on an old Fuji controller which I though I'd NEVER figure out.

I would start by trying to figure out what the operators are. ! seems to mean LD or STR. / might mean AND or OR. You'll have to look for clues in the program to determine which it is. I think it's a pretty safe bet that = means OUT.

The biggest hurdle will be if there are any special purpose bits or instructions used. Clock bits, one-shots, etc. might be stubling blocks.

How large is the listing? If you can post it here as a text file, I'm sure a few of us would be willing to take a crack at deciphering it.

The old SST facility in Heidelberg, Germany is responsible for the Procontic product lines. They were purchased by ABB and there is help available. Call them at ++49 62 21/7 77-0 and ask for the helpline.
