I made my own using the following:

In the AutoCAD R12 file there is a complete drawing of a RS232 to
20mA Current Loop converter, suitable for data access or programming
functions.
It works on all Simatic S5 CPUs (tested on 100U CPU 100/102/103,
115U CPU941/942/943/944, 135U CPU928, not tested on 150U and 155U)

Since this is a PASSIVE converter (the current source is fetched
from the PLC port), it is not possible to program other devices
such as CP526/CP527 or OP393/OP396/OP5 etc., which require an ACTIVE
(with separate power source) converter.

Istructions:

- Open the file with AutoCAD R12 or higher.

- set the correct scale ratio in your computer to print the drawing
(spacing between the pins of the ICs must be 2.54mm)

- print the drawing onto a plastic transparent sheet (you may
print it on white paper and then photocopy it on plastic sheet)

- use the plastic sheet as master to obtain your printed circuit
by using photo-sensible boards.

Hi mick_5l,

Can you please send the link again I am not able to download the file. or is there is any way to upload the 150 U CPU924 program.

Thanks,

Good evening
can any re-upload the schematic of cable programming S5 plc.

The schematic of S5 adapter I made myself more than 20-ty years ago. Now You probably can't find out cellular phone data cable, so use USB-RS232 TTL cable.
The schematic is quite simple to understand how does it works.
