   AC 800M Controller and CI869 In the Control builder hardware tree with CI869, the DSPs (DSP Send and DSP Receive) are located under the hardware units My DSP Group, DSP Group, and AF 100 Station with DSPs. If one or several DSPs are error marked or not transferred on the bus, the DSP device specific status is displayed in the Unit Status tab of the hardware editor in Control Builder. Table 55 provides the status indications and their description for the DSP Send or DSP Receive hardware unit.This indicates that no data is received for a certain DSP, although the bus master function is active. The error persists until data is received. The reason for this error can be found at the Advant Controller which contains the sending DSP. Probably the Advant Controller containing the sending DSP has crashed, or the sending DSP is currently not active.

EventSet Errors in the Advant Controller 400 Series 

In the Advant Controller 400 Series errors are detected with system messages and the EVS(R) data base element ERR and WARNING terminals. EventSet uses message transfer on Advant Fieldbus 100 and therefore no configuration is performed and by this no configuration errors can appear. Errors depends on not received events, there are two possibilities why data is not received see Table 56.The EventSet (EVS(R)) is not receiving any events from the sending EventSet (EVS(S)) in the Advant Controller 110 node depending on a bad value on the S_USER, S_BUS and S_STATION terminals.The source EventSet does not answer, that is it is switched off, the contact with the communication interface is lost or a communication error has occurred on the used communication media.

CI5221 Communication Interface 

The CI522 communication interface is used in the Advant Controller 400 Series. The communication interface can handle about 4000 CDPs and have full functionality of a bus administrator, it can be a bus master on the bus. Two CI522s can form a redundant CI522 pair in which one board acts as primary while the other acts as back-up. Front Panel of the Communication Interface CI522 The front panel of the CI522 contains four LEDs and two contacts for connection to Advant Fieldbus 100 Modems.
