90 RSLinx – Training Guide
More TCP diagnostics are found under the General, Performance, Connection Event
Log, and Active Connections tabs in the tabbed dialog.
TCP diagnostics are modeless windows; therefore, they can remain on the desktop if
you minimize RSLinx. The Driver Diagnostics for TCP box is shown below:
Server Diagnostics are found under the DDE/OPC menu - Server Diagnostics. Server
diagnostics are modeless; therefore, they can remain on the desktop if you minimize RSLinx.
Select Server Diagnostics from the DDE/OPC menu to display the following diagnostic
counters:
• Number of Conversations - The number of DDE Conversations handled by RSLinx.
This is normally the same as the number of clients talking to RSLinx; however, this
is not always the case.
Ø Using a Visual Basic client, each DDE display is another conversation to
RSLinx. Therefore, you could have a Visual Basic Client requesting five
separate items, and have five conversations, or have Excel requesting
thousands of items, and have only one conversation.
• Text Item Count - The number of DDE Items talking to RSLinx via the CF_TEXT
DDE Protocol.
• Text Poke Count - The number of DDE Pokes sent to RSLinx from DDE Clients via
the CF_TEXT DDE Protocol.
