Uhh. it is actually now bigger problem than it used to be. I asked the SW engineers and they all said that it is nearly impossible to get any of the S5 application program running on modern/latest laptop.
1: First problem is the physical: The current loop dongle works only with real RS-232 serial port, docking stations do not support it. There is a rumour that one USB-dongle worked with it, but newer models don't. Even when they state they do.
2: Windows version. S5 aplication programs are very old. Basically if you need to program EEproms (or even Eproms) for cumminacion cards etc. it's nearly no-go. They have one ancient PC from someone's home that runs with all those programs. There were some laptops that run the old programs and were used, but I.T. tries to hunt them down and confiscate (security risk, old operating system, danger of connecting them into internal network......). Situation has got worse from 2013 after big downsizing/move.
Do you have the cables and serial to current-loop converter + all the cables?
I'm going to ask someone I'll meet later this week what are they useing to connect obsolote S5, I know we have the projects and least some of them would benefit greatly if there were a way to connect to live PLC and see what is actually running and what I/O is being adressed (after 20 years of use and countless rebuilds mills tend to add some aux controlls to closest available PLC and much joy if the sump pump or extreaction fan is disconnected permanently).
I am sorry about the bad news. I wish I had stached some of the stuff they trashed 5 years ago.

Pekka, I have a working Panasonic Toughbook CF-50 running XP with a real RS232 port - in fact I loaded OPERA browser on it only this morning as Chrome, Firefox etc no longer support XP
What i don't have is the software, the dongle, or the cable. No doubt the RS232 to current loop can be sorted relatively easily.
As an alternative I am watching this on eBay :
https://www.ebay.co.uk/itm/Siemens-6ES5675-0UA11-Simatic-S5-PG675-Programmierger%C3%A4t/113100786538?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
But I'm not sure if those two floppies represent all the software that is needed.
Also I am following this programmer, which I think is the correct one:

BTW thanks for remembering :thumbup:
PekkaNF:
For serial communication, we needed
1: Cable from PC RR-232 to converter
2: Wall wart for converter and converter
3: Cable from converter to PLC, there were least two types one D15 and one D25
Something like these:

I remember working with U115, U135, and U155 CPUs. Sometimes we had to solder the cables, when they got lost, broken or worn. I think the currentloop converter was internaly fairly simple affair like two optocouplers, resistors to set the current and constant current source. Something like this:
*bit more google, I don't rememenber seeing these, but I could be the right thing*

I am not sure if the floppies are reliable after all these years, least I can't open the files from the floppies I had from that time. Still more reliable than 3.5".
This is how the boot looks like:
PG 685 would have a HD and all programs on that one. Darn. Now when I think of it, I have forgot most of it. There some other like PG 740/750.
You really have a knack of finding a challenge.

I spent some more time today trying to investigate why I can't get the Renishaw optically coupled probing system working.
It consists of four elements:
An MI12 'Machine Interface' - (A box that talks to the Siemens control and the OMM )
An OMM (Optical Module Machine - machine mounted infra red sender receiver )
An LT02 (Tool Turret mounted infra red sender receiver)
An LP2 that mounts on the LT02 (a sensitive switch operated by a probe touch)
What is supposed to happen, is that the MI12 tells the OMM to 'wake up' the LT02 as it has an internal battery that needs preserving. Once awake, if the ruby probe tip trips the LP2 switch element, the LT02 transmits a signal to the OMM, which passes it to the MI12, which gives a signal to the Siemens controller that we are in contact.
awemawson:
Now from previous work I had proved that the OMM is transmitting an IR 'wake up' signal, comprising a 250 millisecond burst of 125 uSec period pulses every second. I did this by cobbling together my own IR receiver.
Now there was no apparent response from an LT02 held in range and triggered. So maybe the LT02 is faulty, or maybe the OMM is not receiving ?
So today's task was to dismount the OMM and have a look at it's electronics and see if I could glean any further information. Not the easiest thing to get at, being behind the machine sliding door, but just possible.
The wires are pretty delicate and extremely short making the job an utter joy !
First the outside glass cover has to come off, and a shroud, giving access to the wiring terminals. To get a bit more space to move, I took the OMM off it's mounting bracket.
