Posted 22 Aug 2006 Hello I have a project where I can use plastic optics fiber. The distance between the 2 Profibus DP participants (Simocode pro) is less than 50 meters and there will be 2 OBT. My questions are: 1. Do I need connecting adapter (6ES7195-1BE00-0XA0)? 2. Is it possible to connect the Simocode pro (which is in the same switch box as OBT) to OBT via terminals A and B (not via 9 pin plug)? (See the attached BMP) 3. Are there every thing needed in the tool set 6GK1901-0FB00-0AA0 for assembling plugs to plastic optics (6XV1821-0AH10) ? Where could I find an instruction for work with that tools set? 4. Is it possible to use the cable 6XV1821-0AH10 outdoor (protected in plastic tube from the sun and mechanical damages, but with ambient tempearture +50…-20°C?
