Note

A teleservice adapter can be connected to the PROFIBUS interface (X126) for remote diagnosis purposes.

Setting the PROFIBUS address

Two methods are available for setting the PROFIBUS address:

1.Via the PROFIBUS address switches on the Control Unit

–In this case, p0918 is read-only and simply displays the set address.

–A change is not effective until POWER ON.

2.Via p0918

–You can only use this method when all the PROFIBUS address switches from S1 to S7 are set to ON or OFF.

–Address changes made via parameters must be saved in a non-volatile memory using the "Copy from RAM to ROM" function.

–A change is not effective until POWER ON.

Example:
