Similar like at LOGO!. Switch the "grey part" to left, you get connected. Switch it to the right, you get disconnected. At 1200 you have no more connector cables at each module. regards

It is used to electrically connect this module to the others on the left side. The mechanism is similar at the Logo! Attachment untitled.JPG (247 Downloads)

lesko Posts: 76 Rating: (1)	Hello, I have a question about that connector. Is it used just for data connection between the modules or is it also used as power-Supply, so that you don't need any external power supply. Thanks for your help, Best regards Lesko
