Replacing the PN/CAN LINK

Below you will find a description of the basic steps required for replacing the PN/CAN LINK.

Preparations

De-energize the S7 configuration including PN/CAN LINK.

Replacing the device

Follow these steps:
1.

Disconnect the 24 V power supply cables and the functional ground from the screw

terminal.

Remove the PROFINET connector and CAN connector.

Disassembling the device from the DIN rail. Proceed in the reverse order to that described in

section Installing (Page 84).

Installing and connecting the new device

Note

The PROFINET device name and IP address of the new device must match those previously

used. Otherwise, the device will not be detected.

Commissioning the device once again

Switch on the power supply for the S7 configuration and the PN/CAN LINK.

The configuration data are downloaded automatically from the higher-level S7 CPU.

The Step 7 program switches the PN/CAN LINK to "Operational" state by setting the control

bits to "ON".
