Problems with the front connector of Siemens PLC S7-300
Thread Content
The front connectors for the 300 series come in 20-pin and 40-pin versions. Can the 20-pin connectors be used interchangeably? For example, are the 16-pin DI module and the 8-pin AI module a type of 20-pin connector?
These of his are all universal. Put simply, it involves integrating 20 or 40 terminals together
Thank you for the guidance. I remember that when installing the connector for the first time, it has a memory function; connectors for different signals cannot be inserted randomly, right?
There is a latch on the back of the connector, and that part can be adjusted.
Hmm, I see. Thank you again for your guidance!
