1747-L553 Communication interface module

　Selecting Station Address Before starting the Advant Controller 70, it must have been assigned a station number. The station number is selected with the address switches on the PM810 front. The station number must be in the range of 1 to 79. Please refer to the Advant Controller 70 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 station number acts as the hardware address of the communication interface on the Advant Fieldbus 100. Restarting Advant Controller 70 There is no difference between starting the first time, and later.

LED Indicators on PM810 

  When starting (or restarting) a PM810, the LEDs (T1 and T2) concerning Advant Fieldbus 100 on the front panel are handled as follows.All LEDs are lit during the hardware init, about one second. The R (RUN) LED is lit when the station is running. The T1 and T2 Leds are lit when the modem can detect any bus traffic (receiving or sending) on line 1 respective line 2.

Exchange of a PM810To exchange a PM810, the following procedure must be followed. As the Advant Fieldbus 70 can not be bus master the communication between other nodes can not be disturbed while exchanging PM810s. Before taking the new PM810 into operation the application must be loaded to the station and the station must be assigned the same station number as the replaced station.

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.
