Schneider Electric 44 - Software Historian Network Bandwidth No Compression2014 P1 w/ Compression 2014 R2 w/ Compression* 92% savings * Applies to tier 1. Tier 2 savings is 18%. No change for Remote IDAS. 53% savings

Slide 45

Schneider Electric 45 - Software HCAL Packet Optimization Rationale: Existing compression ratio was not good for data streaming packet ~ 20% Customer requires better utilization of bandwidth. Analysis: Unique Tag ID precedes every VTQ causing low compression ratio. Method: Build tag dictionary - Tag handle (DWORD) for each Tag ID for each connection session. Use Tag Handle instead of Tag ID in the packet. Result: Compression ratio improved ~ 92% Optimization enabled when compression is enabled. Transparent to user. Slight increase of Resource Usage

Slide 47

Schneider Electric 47 - Software HCAL Diagnostics When Fail to Connect: On Client Computer: Set LogFlag aahClientCommon[Connection] to see WCF exception stack. On Historian Computer: Check warning messages. Possible Cause: Invalid Historian name, firewall blocking, incorrect port, invalid credentials etc. To See Tag Information: Set Registry Setting [HKLM\Programs\aahClient] TraceGlobal=dword:1 Trace files will be created under c:\aahClientCommon-TraceGlobal Toggle LogFlag aahClientCommon[TagDump] to see tags reported in the corresponding file. To Trace Tag Values See Tracing Document

Slide 48

Schneider Electric 48 - Software HCAL Diagnostics To See Buffer Type and Count Set LogFlag aahClientCommon[BufferCount] Buffer Type SF Partial Store/Forward (Tags not synchronized or values time less than cut-off time) Buffer Type Streaming Regular Buffer To See Buffer Destination (Historian or SF) and Size Set LogFlag aahClientCommon[BufferTransmit] To Find Out Reasons that Store/Forward Files not Forwarded: Set LogFlag aahClientCommon[StoreForward]. Or Set Registry Setting [HKLM\Programs\aahClient] TraceGlobal=dword:1 and check the trace file.

Slide 49

Schneider Electric 49 - Software HCAL Diagnostics To See Data Transmission Activities in HCAL: Set LogFlag aahClientCommon[Operation] To See Status Checking/Management Activities Set LogFlag aahClientCommon[ServerStatus]

Slide 50

Schneider Electric 50 - Software HCAP Diagnostics To See Incoming Requests from All Clients Set LogFlag aahClientAccessPoint[Operation] To See Status Checking/Management with Clients and Other Components: Set LogFlag aahClientAccessPoint[ServerStatus]. To See Buffer Information Received from Clients: Set LogFlag aahClientAccessPoint[BufferTransmit] To See Status Checking/Management Activities Set LogFlag aahClientCommon[ServerStatus]

Slide 51

Schneider Electric 51 - Software HCAP Diagnostics To Trace Tags from Client See Trace Document To See Tag Information: Set Registry Setting [HKLM\Programs\aahClientAccessPoint] TraceGlobal=dword:1 Trace files will be created under c:\aahClientAccessPoint-TraceGlobal Toggle LogFlag aahClientAccessPoint[TagDump] to see tags and their last value received.
