Hello !
Siemens S7-200 PLC is the most popular PLC in the world, it is really a legend ^^. Any automation engineer knows it and collides with it, but not everyone has available cables to connect to the PLC and its price is not cheap.
Today I would like to guide you to make 1 Siemens S7-200 PPI PLC programming cable
- The items needed to make cable :
+ COM DB9-Male 
+ COM DB9-Female 
+ Led Green 
+ R : 3kΩ / 5kΩ / 680Ω 
>>> You make cable according to the following diagram
I did and tried to download / upload with the PLC and found everything OK. I wish you success ^^
