IS230TCISH6C Gas turbine module

   “Multiple devices“ One or more stations use the same station number as this station. Check the station number in the different stations on the bus. The error message can also indicate disturbances on the bus. Check the installation.“Too High Station Number” Too high bus master station numbers are used on the bus, quick switch over times can not be guaranteed. When CI522 redundancy is used in an AC 410 or AC 450 a requirement is that at least two bus masters or one redundant CI522 pair is given station number 5 or lower. The message is displayed once at start of the redundant CI522 pair, for example at system start up.Minor device/station error. The device/station has some minor error that does not make the device/station unusable.Fatal bus error. Either Advant Fieldbus 100 cable, modem or driver error.

Error Detection In Advant Controller 110/160 

Not in Operation Fatal module error cause the communication interface to restart and to remain in error state thereafter. See Table 4 for usage of CI630/CI631. The individual error indications are described below. Most of the errors indicate fatal hardware errors, requiring that the communication interface must be replaced. The reasons why the CI626/CI627/CI630/CI631 is not in operation are: • The CI626/CI627/CI630/CI631 data base element terminal IMPL is set to zero. • The module is out of order. • Several stations are using the same station number. • The station number defined in data base differs from the value defined on the thumbwheel switch. • If the bus is not terminated, the CI626/CI627/CI630/CI631 do not work properly. • The CI626/CI627/CI630/CI631 (only capable of running on a bus configured for 2000m) is connected to a bus that is configured for 8500 meters or 15000 meters.

Restarts during Operation 

Since the communication interfaces CI520/CI522 and CI626/CI627/CI630/CI631 are based on the same bus coupler firmware, the reasons for restart of CI626/CI627/CI630/CI631 might be the same as described in Restarts during Operation on page 204. Besides, Advant Controller 110 permanently performs background diagnosis for all modules. If the diagnosis detects an error on the CI626/CI627/CI630/CI631, the reconfiguration is started in case of parameter mismatch between application software and CI626/CI627/CI630/CI631. During that action, errors described in CI626/CI627/CI630/CI631 Status Information on page 99 may occur, and other communication interfaces on the bus may be affected, too. If the CI626/CI627 still performs restarts, a rough way of initialization can be used by pulling out the module for at least five seconds. If after the restart the module remains not operational, see Not in Operation on page 210.
