ABB 800Xa PLC Connect Alarm and Event List,Line Problem
We have ABB 800xa PLC Connect 5.0.2 system in our Plant,
we have Clicked PLC Uploader ,for updating tags and deployed later the PLC controller didnot deploy correctly and check again it given message No deploy required may be it not correctly uploaded, after 5-6 min later suddenly,all values in the SCADA page lost communication with the connectivity server and all the scada pages came to "0" Values and no running indication in the scada page for this issue we have solved it by restarting the PLC_Server and OPCDA_Connector services,we were happy that plant dint shutdown only scada lost communication in the meantime every value in the scada came to services and all values updated after restarting those 2 services,
But In Alarm Line in the operator workplace repeatedly we are getting PLC_1 alarm in the alarm and event list for every new generated alarm repeadtly we are getting alarm "PLC_1" in the alarm line and Alarm & event list as operator is under confussion which alarm he his getting couldnt able to notice, for this issue to solve i have restarted Alarm_Manager, Event Collector--> ABB 800xa Soft Alarm OPC Server,Process Alarms,System Mesage services, and under the Process Alarm under Service Group definition--> Special Configuration--> Alarm server: Ads OPC Event Server and Collection Definition Ads OPC Event Server and Object handler: default source object interceptor is selected and uploaded and restarted the service, but this issue dint solve.
I have disconnected Alarm and Event Smiley :) under OPC Server AC 800M Connect, the Smiley came healthy but alarm still updating as PLC_1 in the Alarm and event list and Alarm line.
I have created new Object type in the control structure in order to test whether alarm and event,line is working or not but when i generate and alarm i am getting Alarms in the Alarm&event and Alarm List updating, but others are not generating with Object name and description only PLC_1 is generating still in the list.
In the Alarm & event list Configuration--> Common Alarm Line Configuration--> under Source-->Alarms--> Category--> Process Alarm--> Select event category is selected by default configuration as we required, after updating all this configuration i am not able to achieve what i required, but for temporary being i have selected Event under Source type and tracking values--> operator action by selecting this i only get operator updation list in Alarm Line and Alarm&Event List but No Ackstate Check box as it is invisble.
As i have created new ALarm and Event Configuration and Link to the Alarm Band with different name for testing but still i get PLC_1 in the list.
if i do PLC_Uploader again there is chance for holding plant and may lead to trip also so we are not going for that option as i feel it very risky at this point.
Kindly Give us Suggestion what to do inorder to correct this issue on high priority basis as we are facing serious issue with alarms.
Note: The settings which you are suggesting kindly see to that the Plant shouldnot Trip or operation-wise shouldn't be any problem, as we are running plant continuosly.
Kindly check the screenshot which i have in the link below.
Please give us suggestion to this critical issue
