Replacing a Controller Link Unit with a Relay Terminal Block
Use the following procedure to replace a Controller Link Unit with a Relay Terminal Block. The communications
cables are left connected to the Relay Terminal Block during the procedure, and only the Relay Terminal Block
itself must be disconnected from the Controller Link Unit and then connected to the new Controller Link Unit.
The following procedure describes only steps required for the Relay Terminal Block. Refer to 9-6-1 Replacing
the Unit for details on the replacement operation.
1. Turn OFF the power supply to the PLC with the Unit to be replaced.
2. Remove the communications terminal block cover from the Unit.
3. Loosen the three screws on the communications terminal block. (If adjacent Units are close enough to in-

10. Attach the terminal block cover to the communications terminal block on the Controller Link Unit.
11. Turn ON the power supply to the new Unit. (The power supply to other nodes should still be ON.)

sure to align the signal lines and shield line with the markings on the Controller Link Unit.
ing torque for the three communications terminal block terminal screws is 0.5 N·m.
Do not allow the metal portions of the Relay Terminal Block or the communications cable crimp
terminals to come into contact with any conductive material.
