HONEYWELL 8C-PCNT01 51454363-175 module

   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.

LED Indicators on CI626/CI627 

  When starting (or restarting) a CI626/CI627 communication interface, the LEDs of the front panel, are handled as follows. The red “FAULT” LED is on, the green “RUN” LED is off, as are all the yellow LEDs. During initialization of the communication interface, the “MASTER” LED will be turned on, and the “CONFIG OK” LED will flash shortly while the scan table is generated When the initialization is done and the relevant hardware checks are performed, the “FAULT” LED goes off indicating that the CI626/CI627 communication interface is ready to be configured. When it has been configured it is automatically set operational (by the CPU), which is indicated by turning on the green “RUN” LED. The Traffic LED is lit when the modem can detect any bus traffic (receiving or sending) on the line 1 or line 2.

\Restarting Advant Controller 110

   When restarting a communication interface, the configuration stored in nonvolatile memory will be valid, and the communication interface will use the loaded parameters rather than the default parameters. Otherwise, there is no difference between starting the first time, and later.
