Function Switch
Fig. 7: KL9050 - Function Switch
• Switch position Next:
The Function Switch of all Coupler Terminals (KL9050) to which a continuing Ethernet cable is
connected must be set to position Next!
• Switch position Last:
Activate the terminating resistor at the last expansion terminal block of your K-bus extension system by
switching the Function Switch on the last Coupler Terminal (KL9050) to the Last position.
Danger to persons, the environment and equipment
ü Correct setting of the Function Switches of all Coupler Terminals (KL9050) within a K-bus extension
system must be ensured!
ü Correct setting of the Function Switches must also be ensured if Coupler Terminals (KL9050) are re-
placed!
ü Please note that all extension terminal blocks connected after a Coupler Terminal (KL9050), whose
Function Switch is set to the Last position, are not included correctly in the process image! This means:
a) The inputs of these terminals are not visible in the process image!
b) The outputs of these terminals are not controlled by the process image!
ð The Function Switch may be set to the Last position only at the last Coupler Terminal (KL9050) of the
K-bus extension system!
Notes on the topology
Notes on the connection of the KL9020 and KL9050 terminals
The end terminal with RJ45 socket (KL9020) may only be used at the end of Bus Terminal blocks
that are opened by a fieldbus coupler! All extension terminal blocks must be terminated by a
KL9010 standard end terminal!
At least one terminal with process image must be connected to each KL9050 Coupler Terminal! The
operation of an extension terminal block with only one KL9010 (with no inputs or outputs) is not per-
missible
Disassembly
When mounting, observe the information in the chapter entitled Mounting rail installation [} 17].
1. Ensure that the system is powered down and in a safe state.
2. Press the plastic lock of the RJ45 plug and pull it from the socket.
3. Carefully pull the orange-colored lug approximately 1 cm out of the terminal to be disassembled, until
it protrudes loosely. The lock with the C mounting rail is now released for this terminal, and the termi-
nal can be pulled from the mounting rail without excessive force.
4. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower grooved
housing surfaces and pull the terminal away from the mounting rail.
