Data Array, but not to the Non-Volatile Memory. Storing
this value has performance impacts, so care must be taken
to store this value only if needed. Refer to Section 5.3
Appendix D.4.3.
Data Arra y Function
The Data_Array_Function Keyword is used in the configuration file to get Data Array specific error conditions and
statistics. The available keywords are listed below:
Keyword
Description
Node_Online_Bits
Bit 0 is unused. Every bit corresponds to the Node with that number up to 255. E.g.: Bit
3 corresponds to Node 3, etc. Refer to Appendix A.1
Node_Error_Bits
Node_Detail_Stat
(Dev_Detail_Stat)
A Data Array is created to reflect Node details. Handle can be set.
Values are reflected in the following order:
0 = Device handle, 1 = Node port; 2 = connection; 3 = old station; 4 = station.
Chan_Detail_Stat
Connection information f
0 = First value handle; 1 = port; 2 = old port; 5 = error count.
Values in Data Array will reflect these values.
Node_Overview_Stat
Gives overview of all devices configured on the FieldServer. Cycles through all the
devices on the FieldServer in the order that they are configured. Note that the Data
Array needs to be long enough to store all device information.
0 = Handle; 1 = station; 2 = port; 3 = adapter; 4 = status; 6 = old station;
10 = Historical message count; 11 = minutes; 12 = hour; 13 = day; 14 = month.
15 = Historical error count; 16 = minutes; 17.= hour; 18 = day; 19 = month.
The next device starts at position 20 and the same structure is repeated. Reporting will
stop after all the devices have been reported or when the Data Array is full.
Chan_Overview_Stat
Same except
0 = handle; 1 = port; 2 = adapter; 3 = status; 8 = old port; 9 = old adapter. Thereafter
follow Historical message and Error blocks in the same format as above.
Dev_Error_Rates
Reports the number of errors per hour for each Node. Location in the Data Array is the
station of the device i.e. if the device station is configured to be 10, position 10 in the
Data Array will show the number of errors per hour. Errors for the past 60 minutes are
stored.
Dev_Msg_Rates
Same as above, except counting messages not errors.
Dev_Error_Percentage Percentage of messages generating errors over the past hour.
Node_Status
Provides the communication status between the FieldServer and the actively mapped
Nodes. Refer to Appendix A.1
