Hi all,
I have to deal with an old project a former fellow employee created, and now he's gone and I was not able to find the related documentation.
The PLC is a ScadaPAck LP.
The project consists in a ladder program (*.lad file) that I was able to open in Telepace, a *.csv file with the registers and its values, a *.cpa file that I was able to open in Information Designer, and a *.abs file.
On internet I found out that the abs file is a compiled C program. Here is where my doubts arise:
1. Do I need the source file (a *.c file) in order to see what the code does, don't I? I believe I cannot retrieve the source file from the compiled file (I hope I am wrong).
2. Do the ladder program and the C program work together in the PLC? I would appreciate if someone could shed a light on this.
3. If I am not able to get the source C code, is there a work around for this? The PLC is on the client site, but they will collaborate with us.
Thank you very much for your help!
