ProtoLink develops I/O servers for the purpose of collecting data from intelligent
devices and sending configuration or command information to these same devices.
These I/O servers expose this functionality to industrial automation and HMI/SCADA
client applications via standard OPC interoperability protocols.
ProtoLink drivers typically support scheduled and interval polling, unsolicited
message handling, poll groups, multi-level priority queuing, and demand polling
of both individual devices and entire poll groups. They also typically provide
a Windows Explorer-like user interface that supports run-time browsing of timestamped
data values, communication statistics, and polling status histories. ProtoLink
drivers make efficient use of multithreading and provide for the display of diagnostic
messages in either ASCII or Hexadecimal format.
