Starting an Advant Controller 110 with a CI626/CI627

When the network has been installed, the Advant Controller 110 can be started.

Initial Start-up When a CI626/CI627 communication interface is powered on for the first time, it has an invalid configuration in its nonvolatile memory. The consequence of this is that the entire configuration table is deleted (that is no CDPs are configured anywhere as far as this communication interface is concerned). The error indication on the CI626/CI627 is lit until the CI626/CI627 communication interface is restarted. The error indication has no consequences for the operation of the communication interface. It is merely a normal start up condition, and may be ignored.

Selecting Station Address Before inserting the communication interface CI626/CI627 into the Advant Controller 110 backplane, the user must select a station address (in the range 1 – 79) on the Advant Controller 110.

The station address is selected on the thumb-wheel switch at the lower left of the backplane containing the basic station (refer to the Advant Controller 110 documentation for further information). The station address has no relation to the order of the stations along the bus. They merely represent physical addresses which are used to refer to specific stations. The Advant Controller 110 station number acts as the hardware address of the communication interface on the Advant Fieldbus 100. Note that the communication interface CI626/CI627 must be inserted in the second slot in the Advant Controller 110 backplane if it should be able to read the station address from the thumb-wheel.
