To clarify a few points.
Moeller plc ranges are
ps20, ps22,ps24 - These were the earliest and still about you need either specialised programming equipment eg prg 22 , prg24 or some software is available but compiler cards are required as no on board ports were available.
PS3 small compact controller bit and byte adressing. Sucos3 software can decompile a program form these or a hand held prg3 is also available. two interfaces exist a card thats a full lentght isa card or alternatively a more modern serial port adapter is available for use with the latest versions of sucos3.
PS316/306 more powerful controller. 316 was modular rack mounted system 306 compact version similar in apperance to a PS3. 316 was available as a byte or word processor. 316 was available as 306 or 306-ee with built in eeprom memory however approx half memory of the ram version.
PS32 Powerful rack system with 32 bit math.
current ranges are called PS4 series and windows based programming.
newest range just out i cant remeber range name but check moeller site.
Sucos , sucos3 , sucos6 were the programming packages for the PS3 range of plcs.
I have a wide range of spares for all systems even the obsolete ones and full programming / modification equipment.
A PS316 without source code can be recovered by reverse engineering and qoutes are made once a copy of the compiled code from the PLC is recieved.
PS32 without source code is im afraid a rewrite for mods/ online programming.
This is not information from reading manuals / playing I was employed by moeller for 5 yrs as an automation engineer and specialised in moeller plcs for a further 10 yrs approx 15 yrs total experience on these plc's.
hope this helps .
