TOP Server 5 User Configurable (UCON) Driver Training
Lauren Conrad
Agenda
• UCON Overview• Example Messages• Simple Read Transaction• Simple Write Transaction• Complex Transaction• Unsolicited Transaction• Resources
UCON Overviewwhen and why to use it
Why Use UCON?
• Allows user to easily create a device driver for devices with no off-the-shelf driver solution• Is completely integrated into the TOP Server just like other TOP Server drivers• Allows user to configure a set of “transactions” through the user interface based on the
protocol format required by the device• Makes device data available to any OPC DA, OPC UA, Wonderware Suitelink, DDE, or GE
iFIX PDB/NIO Client• Requires no programming experience• Provides access to barcode readers, scales, gauges, etc.• Eliminates need for expensive and unreliable alternatives (i.e. custom driver development,
manual data entry, interfacing device to a PLC, etc.)
Evaluating the Protocol
• How Complex is it?• How is the data presented?• How many items will the driver be requesting?• How are the packets terminated?• How do we connect to the device?• Is the device a slave or a master?

Creating an Unsolicited Channel
• Enable Unsolicited mode by checking the box• Receive timeout- the amount of time the driver should wait for the unsolicited
message to come in• Dead time- allows TOP Server to re-synchronize itself with the device(s) after
receiving a message with an unknown key• Key length- tells the driver how many characters to use as transaction keys (must
be the first characters in a message)• Log unsolicited message timeouts- places a message in the event log when the
"Receive timeout" period expires while receiving an unsolicited message
Creating an Unsolicited Device
• Wait Time- how long the device waits for an unsolicited message before triggering the _UnsolicitedPcktRcvdOnTime system tag
