Components from ACM 8 cannot be combined with components from ACM 7.

Features Added

New Honeywell Mercury Protocol

• Added support for fixed temperature and pressure in audit records.
• Added support for additional Live Read items.
• Implemented GC Write Service support.

Teledyne CA Protocol

• Added validation to the Greycode conversion for the TeledyneCA protocol.

Issues Fixed

ACM Client General

• Corrected an issue that occasionally caused comm stats to show values greater than 100 percent.

  Reports that may have shown comm stats greater than 100 percent should now show the correct value.

  
  

ACM Publishing

• Corrected an issue in the CFX publishers so ACM correctly publishes the Differential Pressure or Pulse value from a history record based on the meter type and the presence of either the Differential Pressure value, the Pulse value, neither, or both.

  CFX publishers will determine the value to store in the DP or Pulse field of history records based on the meter type and the presence of DP or Pulse data.

  
  

All Protocols

• Corrected an issue that caused the ItemCount OPC item value to lag behind the actual count of items.

Flow-X Protocol

• Corrected an issue that caused an invalid meter record to be stored in the meter history table when station meters on a device were incorrectly configured.

New Honeywell Mercury Protocol

• Corrected an issue that could cause the RetrieveHistory item to maintain a value of negative one (-1).
• Corrected an issue that prevented the TimeSync item's value from updating.
• Corrected an issue that caused the TimeSync item to appear in OPC browse list twice.
• Corrected an issue that prevented the RequestMeterConfig item from appearing in the OPC browse list.

• Corrected an issue that caused the gas quality configuration value for Pentane to be published as Heptane.

  Meter gas quality configuration values Pentane and Heptane will now have correct values.

  
  

• Corrected an issue caused the meter configuration static pressure units to be published multiple times.

  Static pressure units will only be published once. This will reduce the number of columns in a CSV meter configuration report.

  
  

• Corrected an issue that caused the logon message to be sent multiple times when using a Continuous Scan cycle.
• Corrected an issue that caused a communication timeout if an item's return data was an empty string.

• Corrected an issue that caused incorrect values to be published for an EC350 meter's K-Factor.

  
  

  Published Meter Configuration K-Factor values for EC350 are now correct. K-Factor units are now published. This will add a new column to a CSV report.

  
  

  
  

• Corrected an issue that caused incorrect parsing of D1 audit record if units’ field was empty.

  
  

  Published audit data will have correct values for 350 series.

  
  

• Corrected an issue that could cause the unit types for pressure and volume to be published incorrectly for an EC350 device

  Unit type fields for pressure and volume now have the correct value for the EC350 series.

  
  

Old Honeywell Mercury Protocol

• Corrected the call-in message sequence to correctly ACK call-ins before proceeding other requests.

ROC Protocol

• Corrected an issue preventing the LastHourlyRecord, LastDailyRecord, LastEventRecord and LastAlarmRecord items from updating correctly after a successful history collection. 

ROMET-AdEM Protocol

• Corrected an issue that could cause the RetrieveHistory item to maintain a value of negative one (-1).
• Corrected an issue that prevented the TimeSync item's value from updating.
• Corrected an issue that caused the TimeSync item to appear in OPC browse list twice.
• Corrected an issue that prevented the RequestMeterConfig item from appearing in the OPC browse list.
