- Exclude Non-External: Use the External GC Reference or External Meter Reference properties to find the correct meter name and device. The default setting is False. To change this setting, select the cell marked “False” and use the drop-down menu.
- Fail Orphaned Requests: Any gas analysis writes that occur during a server shutdown will be marked as “failed”. The default setting is False. To change this setting, select the cell marked “False” and use the drop-down menu.
- FlowCal Area Index: Use this setting to associate ACM with one or more specific measurement areas in your FlowCal system. The default setting is empty - which means ACM will handle all measurement areas. To limit ACM to a specific measurement area, enter the integer value of the measurement area index. You can also enter multiple integer values separated by commas to make ACM handle a specific set of measurement areas. For example, enter "1,3,4" (without quotes) to make ACM handle requests from measurement areas 1, 3, and 4.
- Max Concurrent Writes: The maximum number of gas analysis writes that can be queued simultaneously. The default setting is 25. To change this setting, select the cell with the numerical value and use keyboard input.
- Request Service Interval Timer: The interval time (in seconds) for the asiGCRequestManager service to process requests. Default is 30. Changes require a restart of the service.
- Trace Logging: This enables logging of gas analysis related progress messages. The default setting is False. To change this setting, select the cell marked “False” and use the drop-down menu.
Gas Analysis Writes Retry
There are six five settings associated with the Gas Analysis Writes Retry that can be modified by the users:
- Max Tries: The maximum number of tries to attempt a gas analysis write for a specific request. This is not used when Switch to Slow Mode is enabled. The default value is 3.
- Slow Timeout: The maximum time (in seconds) to allow for a gas analysis write to complete before putting in the retry list. The default value is 300.
- Switch to Slow Timeout: The maximum time (in seconds) to allow the Write Timeout to complete a gas analysis write before switching to the Slow Timeout. The default value is 500.
- Use Switch to Slow Mode: Enable Slow Timeout schedule for request and retry attempts once the Switch to Slow Timeout has triggers. Max Tries is ignored when Enabled. The default value is False.
- Write Timeout: The maximum time (in seconds) to allow for a gas analysis write to complete before putting it in the retry list. The default value is 180.
Retry configuration examples
The Gas Analysis Writes Retry properties can work in 'regular' mode or in 'slow mode'. The section below describes how each mode works.
'Regular Mode' is active when the property "Use Switch to Slow Mode" is disabled. In this mode, retries follow this logic:
- Each GCWrite request is attempted up to the "Max Tries" value.
- Each attempt can take up to "Write Timeout" seconds to complete.
- If an attempt succeeds, the request is marked as 'Complete' and no more action is required.
- If all attempts fail, the request is marked as 'Failed' and no more action is taken.
- If ACM is stopped while a request is in progress, the request is marked as 'Failed' unless the property to "Fail Orphaned Requests" is disabled. If disabled, any remaining retries will be attempted when ACM is started again.
'Slow Mode' is active when the property "Use Switch to Slow Mode" is enabled. In this mode, retries follow this logic:
- Each GCWrite request is attempted, allowing up to "Write Timeout" seconds to complete. There is no "Max Tries" limit.
- If an attempt succeeds, the request is marked as 'Complete' and no more action is required.
- If the request has not yet completed when the "Switch To Slow Timeout" period has elapsed (since the start of the first attempt):
- Attempts will continue indefinitely.
- Each attempt can take up to "Slow Timeout" seconds to complete.
- If an attempt succeeds, the request is marked as 'Complete' and no more action is required.
- If ACM is stopped while a request is in progress, the request is marked as 'Failed' unless the property to "Fail Orphaned Requests" is disabled. If disabled, retries will resume when ACM is started again.

- Archive Schedule: This enables users to configure when the Archive Manager process runs.
- Do not run automatically: The archive process will only run if triggered to run manually.
- Run every hour at # minutes past the hour: If 55 is entered for minutes, the archive process will run at 1:55, 2:55, 3:55 and so on.
- Run once a day at entered time
- Detail Logging: This option allows users to show logging messages for starting and completing calls through the Report Service, such as, Archive Management and Scheduled Reports.
