Jurassic PLC...?

[bobco]

Hello guys, I need to read the program that is inside a very old PLC. No information about the manufacturer. It seems a German PLC, like a Siemens S5-115 but without PG port. The PLC is installed in a aluminium rack and all modules have the front in aluminium. The only information that I found from the hardware are: Alim FG2131 CPU 4 K FG2101 INPUT FG2112 IN_OUT FG 2150 TRIAC FG2125 May you help me to find information? Thanks in advance.

The "Alim" in the 1st module makes it sound like it is a french PLC. Alimentation = supply , i.e. power supply.
