Hello,
I am an old industrial plc programmer.
I am trying to help a friend who has a house with a very old IHC contol ssystem.
The system has become very unstable and we need to update it.
Many of the modules are no longer available for replacement.
It was sold here in Norway branded as 'Thorsman'.
This system has a controller with a 9 bin port.
There are 18 I/O modules throughout the house.
There is almost no documentation here however I do have a printed
text file dated 1997.
an example line from the program:
Funksjonslinje for inngang 1.
>: OnU001 FolU002
<: END
This line is readable but I don't know where the physical input 001 is.
There are no visable adress dip switches on the modules so I have no
idea where these adresses are placed.
I need some documentation/manual to guide me through decoding the system
such that I can make a symbol table and document 'what is here now'.
No doubt I'm missing something as I don't see this correlation in the
software I downloaded either.
