I want to connect them with the plc simatic s7-300 but without to use any interface device between them. The problem is that i cannot find the pdf-manualsfor them. The first has 4 cables (BK, WH, BU, BN)and the second has 3 cables (BN, BK,BU). Does anyone know about them? I think that the three cables for the firstsensor are forGND, +24V andOUT.For what is the4th cable? Thanks in advance, Sotos
