RSLinx – Training Guide 93
Select DDE Client Diagnostics from the DDE/OPC menu to display the following
diagnostic counters:
• Module Name -The application’s executable name that is talking to RSLinx.
• Topic - The DDE Topic the DDE Client is talking to.
• DDE Format - The DDE Format the DDE Client is using in this topic.
• Item Count - The number of items on this conversation in this
DDE Format.
• Poke Count - The number of pokes sent via the DDE Client module in this
DDE Format.
• Packets Hot - The number of advise updates sent to the DDE Client module
in this DDE Format.
• Packets Cold - The number of request updates sent to the DDE Client module
in this DDE Format. A conversation in PackedDDE or FastDDE does not
support requests, so this is always zero for those formats.
• Request Timeouts - The number of requests that failed during a request for
data in this DDE Format.
• Class Name - The class name of the module's DDE handling window. This is
useful to determine whether the client is using DDEML or using DDE
Messages.
• Process Id - The process ID of the application. It is useful to determine if there
are two or more instances of the above module name running and whether it
is a separate conversation from the program, or whether it is another
instance.
• Elapsed Time - The length of time this conversation has been connected to
RSLinx.
