The SubNetIO application is used to obtain IR
Tag data from a CollectIR
system.
The SubNetIO application can be configured to send arriving tag data to one or more Event
Processors using either DDE, NetBios or TCPIP communications. Multiple SubNetIO
applications can be run on a network allowing data to be collected from any number of PC's
connected to CollectIR Concentrators (Internal, Arcnet or Ethernet). SubNetIO can be
run under Windows 3.11, Windows 95/98 or Windows NT 4.0.
The following screen depicts the typical appearance of the SubNetIO application.
The following is a brief description of each field displayed.
 | Blocks Received - CollectIR sends up to 12 tags per block, this is how
many blocks have been received |
| Tags Received - This is the number of tag receptions from CollectIR |
| Receive Errs - This is the number of Blocks/Tags which contained
invalid data. If this number gets large then there is probably something wrong with
your hardware/configuration. |
| SubNet Ignores - If SubNetIO is busy processing transmit requests it
MAY ignore incoming data, this counter indicates how many blocks of data have been
ignored. |
| Traps Received - If the CollectIR SNOID DLL traps an error this counter
is incremented. See your SNOID.LOG file for details. |
| Send after - This value indicates how much transmission delay/buffering
that SubNetIO is configured to perform. In systems with many tags, it is desirable
to have SubNetIO buffer transmissions to the Event Processor to achieve better system
efficiency by minimizing the number of transmits made to the Event Processor. |
| Sends Queued - This is the total number of sends queued for
transmission currently. If communications to your Event Processor are working
smoothly, this number will remain zero. If your system/network becomes very busy you
may see some queuing. No data is lost, it is just delayed until the system/network
gets time for transmission. |
| EP Sends - This is the number of data transmissions to your Event
Processor. |
| EP Send Errs - This is the number of transmits which were attempted,
but errors occurred in the transmission. In many cases this will cause the data that
was to be transmitted to be queued (see Sends Queued) |
| Last EP Send Size - This is the number of tags that were last sent to
the Event Processor. This gives you some idea regarding the volume of tag
transmissions being sent to the Event Processor. |
| Send to - This is either a DDE/Name or NetBios name used to communicate
with your Event Processor, or it is the TCPIP address/Port of your Event Processor. |
