BENTLY 330180-90-05 Monitor module

When the DSPs have been deleted, the communication interface CI626/CI627/CI630/CI631 can be removed. If the transmission between the other still remaining communication interfaces shall not be disturbed it is important to make sure that the communication interface is never removed while the LED “MASTER” is on. This can be achieved by switching off the power of the affected station or removing the bus cable immediately after the LED “MASTER” goes off (which means that the responsibility for the bus master function has been passed over to the next communication interface). The remaining communication interfaces will automatically continue to share the bus master responsibilities between them and ignore the removed station.

Removing a CI626/CI627/CI630/CI631

 If the communication interface is to be permanently removed, all configured DSPs must be deleted in all stations on the bus having DSPs configured to or from the affected communication interface. If the DSPs are not deleted, the corresponding CDPs will be kept in the scan tables and thereby occupying valuable bandwidth.As a sending CDP must be deleted from the station by which it is configured, the CDP signal address can not be used by any other station unless the whole bus is restarted. This might also generate errors indicating missed CDP transmission.

CI626/CI627/CI630/CI631 Status Information

 Status information about the communication interface CI626/CI627/CI630/CI631 is available during download of application to the Advant Controller 100 Series CPU,by reading the error buffer of CPU or via module diagnostics. The latter one is described in documentation of corresponding diagnosis tool. Error that occur during configuration of the communication interface by Advant Controller 100 Series CPU and those that occur during normal operation are inserted into CPU’s error buffer. The following list contains a summary of those errors.
