1.3.3 Field bus interface
There is a 9−pin sub−D socket on the CPX terminal for
connecting it to the field bus.
This connection serves for the incoming and continuing field
bus cable. You can connect the CPX terminal with the field
bus plug from Festo type FBS−SUB−9−GS−DP−B.
Note
Only the Festo field bus plug complies with IP65.
Before connecting sub−D plugs from other manufacturers:
· Replace the two flat screws with bolts
(type UNC 4−40/M3x5).
